In simple words, the coordination of existing creatures and their periodic evolution along with the existed creations is collectively called Nature. </span><br /> <span style="font-size: large;"><br /></span> <span style="font-size: large;">Creations: The creations are abiotic (non-living) components of nature. They do not possess functional or reproductive properties. It may or may not have a defined physical form but exist permanently. The abiotic components of nature are Pancha Mahabhutas (Earth, Water, Air, Ether, Fire).  The abiotic components are indestructible, which can interchange among states by the transfer of energy, the influence of abiotic factors such as collision, diffusion, temperature, pressure, etc., and activities caused by biotic factors including anthropological activities. </span><br /> <span style="font-size: large;"><br /></span> <span style="font-size: large;">Creatures: The creatures are biotics (Living life and non-living reactive biomaterials) that posses a life cycle, energy cycle and hereditary cycle in a physical form. Throughout life, the biotics depend on the abiotic components for energy and afterlife the energy will be drawn back to abiotic nature. The role of biotics in nature is to maintain the ecological energy balance (energy circulation inside the biotic system) and to regulate environmental energy balance (energy regulation outside the biotic system).</span><br /> <br /> <span style="color: magenta; font-size: large;"></span> <br /> <div class="separator" style="clear: both; font-family: "times new roman"; font-size: medium; font-style: normal; font-weight: 400; letter-spacing: normal; margin: 0px; text-align: center; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;"> </div> <br /> <table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="-webkit-text-stroke-width: 0px; font-family: "Times New Roman"; letter-spacing: normal; margin-bottom: 0.5em; margin-left: auto; margin-right: auto; orphans: 2; padding: 6px; text-align: center; text-decoration-color: initial; text-decoration-style: initial; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px;"><tbody> <tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgDmwX4NYm-AyF0J9Bf5zKO4hajtM_D9pld1LIbU93x7r-9_1okSIAAw59LZ77X7Wv1gOYoUKGFhyphenhyphenZ1kQnvyEyxjTAb3TX9eNdhWZg3-hw-Ywtd43X4dbKZNcbYTuZu5FrHoUB0VfNyzpI/s1600/bioscience.jpg" imageanchor="1" style="margin-left: auto; margin-right: auto;"><span style="color: black;"><img border="0" data-original-height="623" data-original-width="835" height="472" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgDmwX4NYm-AyF0J9Bf5zKO4hajtM_D9pld1LIbU93x7r-9_1okSIAAw59LZ77X7Wv1gOYoUKGFhyphenhyphenZ1kQnvyEyxjTAb3TX9eNdhWZg3-hw-Ywtd43X4dbKZNcbYTuZu5FrHoUB0VfNyzpI/s640/bioscience.jpg" width="640" /></span></a></td></tr> <tr><td class="tr-caption" style="padding-top: 4px; text-align: center;"><span style="color: lime; font-size: small;"><b>Phenomena of Nature</b></span></td></tr> </tbody></table> <br /> <span style="font-size: large;">The Elements Theory: </span><br /> The Elements Theory<br /> <table class="greenTable"> <thead> <tr> <th>Panchamaha<br /> Bhootas</th> <th>Spiritual<br /> Elements</th> <th>Vedic<br /> Astrology</th> <th>Sanskrit</th> <th>Wu Xing<br /> Elements</th> <th>Roman<br /> Elements</th> <th>Zodiac<br /> Elements</th> <th>Body<br /> Elements</th> </tr> </thead> <tbody> <tr> <td>Agni</td> <td>cell2_1</td> <td>cell3_1</td> <td>cell4_1</td> <td>Fire</td> <td>Fire</td> <td>cell7_1</td> <td>cell8_1</td> </tr> <tr> <td>Prithvi</td> <td>cell2_2</td> <td>cell3_2</td> <td>cell4_2</td> <td>Wood</td> <td>Earth</td> <td>cell7_2</td> <td>cell8_2</td> </tr> <tr> <td>Vayu</td> <td>cell2_3</td> <td>cell3_3</td> <td>cell4_3</td> <td>cell5_3</td> <td>cell6_3</td> <td>cell7_3</td> <td>cell8_3</td> </tr> <tr> <td>Jala</td> <td>cell2_4</td> <td>cell3_4</td> <td>cell4_4</td> <td>Water</td> <td><br /></td> <td>cell7_4</td> <td>cell8_4</td> </tr> <tr> <td>Aakash</td> <td>cell2_5</td> <td>cell3_5</td> <td>cell4_5</td> <td>cell5_5</td> <td>cell6_5</td> <td>cell7_5</td> <td>cell8_5</td> </tr> </tbody> </table> <span style="font-size: large;"><br /></span> <span style="font-size: large;"><br /></span> <span style="font-size: large;"><br /></span> <span style="font-size: large;">According to Vedic Astrology, mother nature is comprised of 5 elements named Agni (Fire), Jala (Water), Vayu (Air), Prithivi (Earth) and Akash (Ether) which are commonly known as Panchamaha Bhoothas. The mythological elements have Like all other planets, our mother earth is also made by the mixture of these 5 elements under varying temperature and pressure conditions. </span><span style="font-size: large;">When we look at the beauty of nature, it is amazing to note that five elements provide the foundation for the physical world. Ayurveda, the Indian traditional system of medicine or ‘“living in tune with nature” recognises these elements, Space, Air, Fire, Water and Earth, as the building blocks of all matter.</span><br /> <span style="font-size: large;"><br /></span> <span style="font-size: large;"><br /></span> <span style="font-size: large;"><br /></span> <span style="font-size: large;">According to Vedic science, when Spirit (Purusha in Sanskrit) takes form as life it is called Prakriti. Prakriti is made up of five elements from finest to grossest: space, air, fire, water and earth. In Sanskrit they are called Akash, Vayu, Agni, Jal, and Prithvi, respectively. Every individual is a microcosm of nature and therefore contains all five elements. Let us examine each.</span><br /> <span style="font-size: large;"><br /></span> <span style="font-size: large;">As Spirit takes form it passes first through space or Akash. The Akash element corresponds to awareness itself. It is the layer beyond the other four gross elements and is responsible for the transmission of sound, including mantra. It is the home of potential and possibility. Akash animates Vayu or air, which allows for movement and thought, and it connects us to the sense of touch and the all-important breath. Akash and Vayu combine to form the Vata dosha in Ayurveda.</span><br /> <span style="font-size: large;"><br /></span> <span style="font-size: large;">Fire comes next and is responsible for heat, desire, motivation and the sense of sight. It allows us to want something, see where we are going as we get it, and digest it once we have it. Agni allows for transformation and Agni dominates the Pitta dosha.</span><br /> <span style="font-size: large;"><br /></span> <span style="font-size: large;">Fire then animates water or Jal, permitting flux, emotion, cohesion and the sense of taste. Excess Jal will lead to unnecessary emotional and sensory dependence. Lastly, physical form corresponds to earth or Prithvi. Anything we can smell contains Prithvi. It is the seat of stability when balanced. Jal and Prithvi together create the Kapha dosha.</span><br /> <span style="font-size: large;"><br /></span> <span style="font-size: large;">The spiritual path is walked in reverse, however, from gross to fine. Prithvi allows the body to become stable, followed by the balancing of Jal, emotion and senses. The stable body and emotions vanquish the struggle of Agni, desire. With deep breathing, Vayu, we connect to present moment. Finally, experiencing the Akashic realm, one rests in his true nature. The Yogic Masters tell us that God-consciousness is beyond all of it.</span><br /> <span style="font-size: large;"><br /></span> <span style="font-size: large;"><br /></span> <span style="font-size: large;"><br /></span> <span style="font-size: large;">An understanding of the elements gives us deep insights into our own and other’s natures as well as the world around us. Just as all the elements are in the world, they are also in us. As Rumi says: ‘We are a drop in the ocean and the ocean in a drop’.</span><br /> <span style="font-size: large;"><br /></span> <span style="font-size: large;"><br /></span> <span style="font-size: large;"><br /></span> <span style="font-size: large;">Fire is the element of the signs of Aries, Leo and Sagittarius, and the Sun, Mars and the South Node of the moon, Ketu. Earth is the element of Taurus, Virgo and Capricorn. Air is the element of Gemini, Libra, Aquarius and Rahu, the north node of the moon. Water is the element of Cancer, Scorpio, Pisces and the Moon.</span><br /> <span style="font-size: large;"><br /></span> <span style="font-size: large;"><br /></span> <span style="font-size: large;"><br /></span> <span style="font-size: large;">In Vedanta, each of the five main planets are linked to an element (with ether as the fifth). The Vedas say that everything emanated from the one basic vibration of ‘Om’ with – Jupiter representing Ether, Saturn – Air, Mars – Fire, Mercury – Earth and Venus – Water.</span><br /> <span style="font-size: large;"><br /></span> <span style="font-size: large;"><br /></span> <span style="font-size: large;"><br /></span> <span style="font-size: large;">The elements have their own qualities. Earth grounds us helping us to be present in our lives but too much earth makes us stuck. Air brings creativity and a tremendous ability to connect seemingly unrelated things with powerful results. Too much air makes us ‘airy-fairy’. The water element helps us connect with others and go with the flow of life. Too much water makes us wishy washy. Fire gives us inspiration, motivation, passion and drive to do things. It can kill, heal, create or destroy. Too much or undirected fire burns and gives anger and frustration.</span><br /> <span style="font-size: large;"><br /></span> <span style="font-size: large;"><br /></span> <span style="font-size: large;"><br /></span> <span style="font-size: large;">We need space for each of the elements to flow and function properly. The elemental strengths and tendencies we have depends on the signs and houses our planets are placed, our rising sign and the inter-relationships of the planets and signs with one another in our birth chart.</span><br /> <span style="font-size: large;"><br /></span> <span style="font-size: large;"><br /></span> <span style="font-size: large;"><br /></span> <span style="font-size: large;">From a compatibility view point, Ariens tend to go best with other fire signs. Similarly earth, water and air signs are all mutually compatible. There are also natural love connections between the harmonious sun signs of fire and air, and earth and water. Opposites also attract so it’s also useful to do a full compatibility analysis.</span><br /> <span style="font-size: large;"><br /></span> <span style="font-size: large;"><br /></span> <span style="font-size: large;"><br /></span> <span style="font-size: large;">On a personal level, it is also interesting to reflect on what elements are lacking or over-used in your life. For a happy and balanced life, all elements need to be in use on a daily basis and in balance. Fire gives us inspiration, excitement and energy for life. Earth gives us acceptance and the ability to be present. Air gives us wonderful creativity and ideas and new ways of connecting dots, seeing things and thinking and doing. Water gives us an ability to flow with what is happening in life and connect with others with healthy boundaries. It helps us move forward and leave the past behind us.</span><br /> <span style="font-size: large;"><br /></span> <span style="font-size: large;"><br /></span> <span style="font-size: large;"><br /></span> <span style="font-size: large;">If are feeling out of balance, reflecting on the elements and how they weave and dance together in your life can help you achieve a more harmonious inner and outer balance. You will be amazed at what you discover about yourself in the process.</span><br /> <span style="font-size: large;"><br /></span> <br /> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: normal;"> <b><span style="font-family: "times new roman", serif; font-size: 12pt;">Definition<o:p></o:p></span></b></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px; text-indent: 36pt;"> <b><span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">Microorganisms</span></b><span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">, or <b>microbes</b>, are very small organisms; many types of microbes are too small to see without a microscope, although some parasites and fungi are visible to the naked eye.<o:p></o:p></span></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px; text-indent: 36pt;"> <span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">Microbiology often has been defined as the study of organisms and agents too small to be seen clearly by the unaided eye—that is, the study of microorganisms.<o:p></o:p></span></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">Microorganisms differ from each other not only in size, but also in structure, habitat, metabolism, and many other characteristics.<o:p></o:p></span></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px; text-indent: 36pt;"> <span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">Microorganisms are found in each of the three domains of life: <b>Archaea, Bacteria</b>, and <b>Eukarya</b>.

Born in the city of Delft in the Dutch Republic, van Leeuwenhoek began his career selling fabrics. However, he later became interested in lens making (perhaps to look at threads) and his innovative techniques produced microscopes that allowed him to observe microorganisms as no one had before. In 1674, he described his observations of single-celled organisms (Little animalcules), whose existence was previously unknown, in a series of letters to the Royal Society of London. His report was initially met with skepticism, but his claims were soon verified and he became something of a celebrity in the scientific community.<o:p></o:p></span></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">1.

He predicted that preventing flies from having direct contact with the meat would also prevent the appearance of maggots. Redi left meat in each of six containers. Two were open to the air, two were covered with gauze, and two were tightly sealed. His hypothesis was supported when maggots developed in the uncovered jars, but no maggots appeared in either the gauze-covered or the tightly sealed jars. He concluded that maggots could only form when flies were allowed to lay eggs in the meat, and that the maggots were the offspring of flies, not the product of spontaneous generation.<o:p></o:p></span></div> <span style="font-size: large;"><br style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; text-align: left;" /></span> <div class="separator" style="background-color: #1c1c1c; clear: both; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; text-align: center;"> <a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhJaDrtOxk5UzSWGLFrQqKxxIFxyfxDjEg4a7ka1-TK4TIq9bVs-Tyi3tvFIiEct-hA3JcZdmmr3lLv0vfSgQef5IuVvyOvvGwgC7-nU-Veuq0-z5YcD7MK0aF5Ai5xuBrPHqKuozofbYk/s1600/Redi+exp..jpg" imageanchor="1" style="color: #dd7700; margin-left: 1em; margin-right: 1em; text-decoration-line: none;"><img border="0" data-original-height="562" data-original-width="1049" height="342" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhJaDrtOxk5UzSWGLFrQqKxxIFxyfxDjEg4a7ka1-TK4TIq9bVs-Tyi3tvFIiEct-hA3JcZdmmr3lLv0vfSgQef5IuVvyOvvGwgC7-nU-Veuq0-z5YcD7MK0aF5Ai5xuBrPHqKuozofbYk/s640/Redi+exp..jpg" style="border: none; position: relative;" width="640" /></a></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <br /></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;"><br /></span></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">In 1745, <b>John Needham</b> (1713–1781) published a report of his own experiments, in which he briefly boiled broth infused with plant or animal matter, hoping to kill all preexisting microbes. He then sealed the flasks. After a few days, Needham observed that the broth had become cloudy and a single drop contained numerous microscopic creatures.

As in Needham’s experiment, broth in sealed jars and unsealed jars was infused with plant and animal matter. Spallanzani’s results contradicted the findings of Needham: Heated but sealed flasks remained clear, without any signs of spontaneous growth, unless the flasks were subsequently opened to the air. This suggested that microbes were introduced into these flasks from the air. In response to Spallanzani’s findings, Needham argued that life originates from a “life force” that was destroyed during Spallanzani’s extended boiling. Any subsequent sealing of the flasks then prevented new life force from entering and causing spontaneous generation.<o:p></o:p></span></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <b><span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">Disproving Spontaneous Generation<o:p></o:p></span></b></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <b><span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">Theodore Schwann</span></b><span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;"> (1810–1882) allowed air to enter a flask containing a sterile nutrient solution after the air had passed through a red-hot tube.

In 1858, Pasteur filtered air through a gun-cotton filter and, upon microscopic examination of the cotton, found it full of microorganisms, suggesting that the exposure of a broth to air was not introducing a “life force” to the broth but rather airborne microorganisms.<o:p></o:p></span></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">Later, Pasteur made a series of flasks with long, twisted necks (“swan-neck” flasks), in which he boiled broth to sterilize it. His design allowed air inside the flasks to be exchanged with air from the outside, but prevented the introduction of any airborne microorganisms, which would get caught in the twists and bends of the flasks’ necks. If a life force besides the airborne microorganisms were responsible for microbial growth within the sterilized flasks, it would have access to the broth, whereas the microorganisms would not. He correctly predicted that sterilized broth in his swan-neck flasks would remain sterile as long as the swan necks remained intact. However, should the necks be broken, microorganisms would be introduced, contaminating the flasks and allowing microbial growth within the broth.<o:p></o:p></span></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <o:p></o:p></div> <table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; margin-left: auto; margin-right: auto; padding: 4px; position: relative; text-align: center;"><tbody> <tr><td><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhD2AuT2L-ZSZO7Az8XNSoSEXp0zzEwJei8qAB880eaa-mzSX_XGTv5t8hFHoflxXrSSLoFmw2rR6yOv1jmVrBroccNB89-qbVzAP0FJupopdSu5MyYJfaZzVxXKwfNATArctDdp9kNi98/s1600/pasteur-microbe-proof-test-experiment-swan-neck-flask_orig.jpg" imageanchor="1" style="color: #dd7700; margin-left: auto; margin-right: auto; text-decoration-line: none;"><img border="0" data-original-height="756" data-original-width="1331" height="361" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhD2AuT2L-ZSZO7Az8XNSoSEXp0zzEwJei8qAB880eaa-mzSX_XGTv5t8hFHoflxXrSSLoFmw2rR6yOv1jmVrBroccNB89-qbVzAP0FJupopdSu5MyYJfaZzVxXKwfNATArctDdp9kNi98/s640/pasteur-microbe-proof-test-experiment-swan-neck-flask_orig.jpg" style="border: none; position: relative;" width="640" /></a></td></tr> <tr><td class="tr-caption" style="font-size: 11.88px;">Disproving Abiogenesis theory (Swan Neck Experiment)</td></tr> </tbody></table> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <b><span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;"><br /></span></b></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <b><span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">Modern era</span></b></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px; text-align: left;"> <b><span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">Contribution of John Tyndall<o:p></o:p></span></b></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">John Tyndall(1820-1893), an English physicist,was able to explain satisfactorily the need for prolonged heating to eliminate microbial life from infusions. He concluded, by exposing infusions to heat for varying times, that bacteria existed in two forms-a heat stable form and a heat-sensitive form. It required either prolonged or intermittent heating to destroy heat-stable forms. Intermittent heating, now called tyndallization, killed both forms since between periods of heat treatment the heat-stable forms changed to heat-sensitive forms.<o:p></o:p></span></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <b><span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">Contribution of Louis Pasteur<o:p></o:p></span></b></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">Louis Pasteur (1822-1895) was born in the village of Dole, France on December 27, 1822 the son of humble parents. His father was a tanner. He was originally trained as a chemist, but his studies on fermentation led him to take interest in microorganisms. His discoveries revolutionized medical practice, although he never studied medicine.<o:p></o:p></span></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">       1 .The term microbiology, as the study of living organisms of microscopic size, was coined by Pasteur.<o:p></o:p></span></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">      2.

He use various forms of nutrient fluid to grow microorganisms and showed that a medium suitable for one might be unsuitable for another ,so for successful cultivation it was necessary to discover a suitable growth medium and to establish optimal conditions of temperature, acidity or alkalinity, and oxygen tension.    <o:p></o:p></span></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">     4. He showed that some organisms were not destroyed by boiling. For the sterilization of fluids he advocated heating to 120^oC under pressure and for glassware the use of dry heat at 170⁰C.He showed that cotton plugs (a primitive air-filtration device) could prevent microbes from reaching otherwise air-exposed sterile broths.<o:p></o:p></span></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">    5. In 1860-1861, he disapproved the theory of spontaneous generation .In a series of classic experiments, Pasteur proved conclusively that all forms of life, even microbes, arose only from their alike and not <b><i>de novo</i></b><i>.</i><o:p></o:p></span></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">   6.

In 1863-1865, he devised the process of destroying bacteria, known as pasteurization. He proved that the 'disease of wine' could be prevented without altering the flavor by heating the wine for a short time to a temperature (55-60^oC), a little more than halfway between its freezing and boiling points. This process (pasteurization) is employed throughout the civilized world today to preserve milk and certain other perishable foods.<o:p></o:p></span></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">   8. In 1865, he was asked to attempt to find the cause of pebrine, a disease which was threatening to ruin the business of raising silkworms, an important industry in Southern France. Pasteur succeeded in demonstrating that this silkworm disease was caused by microscopic germs, protozoa, and showed that the infection could be eliminated by choosing for breeding only those worms which were free of the parasites. This discovery was one more step towards the establishment of the truth of the germ theory of disease.<o:p></o:p></span></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">  9. In 1877, Koch and Pasteur demonstrated that anthrax is caused by bacteria. Pasteur grew the organisms in sterilized yeast water and kept them in the laboratory for several months, transferring them frequently to new culture fluid, in which they multiplied readily, and showed that these cultures would always cause anthrax when inoculated into healthy animals.<o:p></o:p></span></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;"> 10. In 1880, he prevented chicken cholera by injection of live attenuated culture. He found that pure cultures of the germ of this disease which had been kept in the laboratory for some time would not kill his animals as fresh cultures did, but would merely cause a passing illness from which the chickens recovered. Then he discovered that the animals that had recovered from a previous inoculation of weakened germs were immune, and did not succumb to the disease. Pasteur immediately perceived that it might be possible to make individuals resistant by inoculating them with the weakened (and therefore harmless) germs of a particular disease.<o:p></o:p></span></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;"> 11.

The crowning achievement of Pasteur was the successful application of the principle of vaccination to the prevention of rabies, or hydrophobia, in human beings and developed <b>Pasteur rabies vaccine</b> in 1885. He did not find the germs of this disease under his microscope (now known as rabies virus) but he was able to propagate them by artificial inoculation into the brains of dogs and rabbits. Finally he developed a system of vaccination with weakened virus which prevented the development of this fatal disease if the inoculations are given soon after the bite of the rabid animal. He gave the first treatment for rabies in 1885 to a rabid dog.<o:p></o:p></span></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;"> 15.

First he used as his growth medium <b>pieces of potato, </b>then 2.5-5.0%<b> gelatin </b>to prepare solid media fortifying them with 1% meat extract as an essential ingredient. He poured melted nutrient gelatin on glass slides and allowed them to set under a bell jar to prevent contamination. He inoculated media using sterile needles or platinum wires dipped in suspensions to take minimum inoculum and lightly drawing lines across the medium. He also developed pour plate method.

He became expert in the grinding of simple magnifying lenses. He made these lenses of small bits of glass, polished them very carefully, and mounted each separately between two brass, copper, silver, or gold plates, to which he fastened an adjustable holder for the object to be examined. He constructed many of these ‘microscopes’ each containing a single lens ground by himself. The best of lenses magnified about 200 times. His microscopes were superior to any of that time, He observed, drew and measured a large number of living organism including bacteria and protozoa in materials such as rain water, pond and well water, and saliva and the intestinal contents of healthy subjects and communicated them to the Royal society of London in 1683. He was the first to accurately describe different shapes of bacteria (coccal, bacillary and spiral) and picture their arrangement in infected material.<o:p></o:p></span></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px; margin-left: 9.75pt;"> <span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">    Leeuwenhoek observed that very large numbers of bacteria appeared in watery infusions of animals or vegetable matter which were left to stand for a week or two at room temperature. He believed that these huge populations were the progeny of a few parental organisms, or seeds that were originally present in the materials of the infusion or had entered it from the air. The significance of these observations was not realized then and to Leeuwenhoek the world of ‘little animalcules’ represented only a curiosity of nature. Their importance in medicine and other areas ofbiology came to be recognized two centuries later.<o:p></o:p></span></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <b><span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">Contribution of Edward Jenner<o:p></o:p></span></b></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">     Edward Jenner (1749-1823) was born in Berkeley in 1749. Orphaned before he was 5-years-old, his brothers and sisters set him on a career of medicine. He completed his training with the great surgeon John Hunter in London. He introduced the modern method of vaccination to prevent smallpox. He observed that milkmaids who contracted cowpox or vaccinia while milking were sub-sequently immune to smallpox. On May 14, 179, he devised a brave experiment. He performed a vaccination against smallpox by transferring material from a cowpox pustule on the hand of a milkmaid, Sarah Nelmes, to the arm of a small boy named James Phipps, his gardener’s son. He failed to develop the disease. By 1798 Jenner published his results in 23 cases and by 1800 about 6000 persons had been inoculated with cowpox to prevent smallpox. <i>The terms vaccine and vaccination were first used by Pasteur out of deference to Jenner.<o:p></o:p></i></span></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <i><span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">     </span></i><span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;"> In 1967 the World Health Organisation masterminded a final global plan to eradicate smallpox.

They were the first living organisms on our planet and live virtually everywhere life is possible. Furthermore, the whole biosphere depends on their activities, and they influence human society in countless ways. Because microorganisms play such diverse roles, modern microbiology is a large discipline with many different specialties; it has a great impact on fields such as medicine, agricultural and food sciences, ecology, genetics, biochemistry, and molecular biology. One indication of the importance of microbiology is the Nobel Prize given for work in physiology or medicine.<o:p></o:p></span></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px; text-indent: 36pt;"> <span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">Microbiology has both basic and applied aspects. The basic aspects are concerned with the biology of microorganisms themselves and include such fields as bacteriology, virology, mycology (study of fungi), phycology or algology (study of algae), protozoology, microbial cytology and physiology, microbial genetics and molecular biology, microbial ecology, and microbial taxonomy. The applied aspects are concerned with practical problems such as disease, water and wastewater treatment, food spoilage and food production, and industrial uses of microbes.<o:p></o:p></span></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px; text-indent: 36pt;"> <span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">A discussion of some of the major fields of microbiology and the occupations they provide follows.<o:p></o:p></span></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <b><span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">Medical microbiology<o:p></o:p></span></b></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px; text-indent: 36pt;"> <span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">One of the most active and important fields in microbiology is medical microbiology, which deals with diseases of humans and animals. Medical microbiologists identify the agents causing infectious diseases and plan measures for their control and elimination. Frequently they are involved in tracking down new, unidentified pathogens such as the agent that causes variant Creutzfeldt-Jakob disease, (the human version of “mad cow disease”) the hantavirus, the West Nile virus, and the virus responsible for SARS. These microbiologists also study the ways in which microorganisms cause disease.<o:p></o:p></span></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <b><span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">Public health microbiology<o:p></o:p></span></b></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px; text-indent: 36pt;"> <span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">Public health microbiology is closely related to medical microbiology. Public health microbiologists try to identify and control the spread of communicable diseases. They often monitor community food establishments and water supplies in an attempt to keep them safe and free from infectious disease agents.<o:p></o:p></span></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <b><span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">Immunology<o:p></o:p></span></b></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px; text-indent: 36pt;"> <span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">Immunology is concerned with how the immune system protects the body from pathogens and the response of infectious agents. It is one of the fastest growing areas in science; for example, techniques for the production and use of monoclonal antibodies have developed extremely rapidly. Immunology also deals with practical health problems such as the nature and treatment of allergies and autoimmune diseases like rheumatoid arthritis.<o:p></o:p></span></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <b><span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">Agricultural microbiology<o:p></o:p></span></b></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px; text-indent: 36pt;"> <span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">Agricultural microbiology is concerned with the impact of microorganisms on agriculture. Agricultural microbiologists try to combat plant diseases that attack important food crops, work on methods to increase soil fertility and crop yields, and study the role of microorganisms living in the digestive tracts of ruminants such as cattle. Currently there is great interest in using bacterial and viral insect pathogens as substitutes for chemical pesticides.<o:p></o:p></span></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <b><span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">Microbial ecology<o:p></o:p></span></b></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px; text-indent: 36pt;"> <span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">Microbial ecology is concerned with the relationships between microorganisms and the components of their living and non-living habitats. Microbial ecologists study the global and local contributions of microorganisms to the carbon, nitrogen, and sulphur cycles. The study of pollution effects on microorganisms also is important because of the impact these organisms have on the environment. Microbial ecologists are employing microorganisms in bioremediation to reduce pollution.<o:p></o:p></span></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <b><span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">Food and dairy microbiology<o:p></o:p></span></b></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px; text-indent: 36pt;"> <span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">Food and dairy microbiology is concerned with the microbial spoilage of food and the transmission of foodborne diseases such as botulism and salmonellosis.

In 1929, Alexander Fleming discovered that the fungus <i>Penicillium </i>produced what he called penicillin, the first antibiotic that could successfully control bacterial infections. Industrial microbiologists identify microbes of use to industry. They also engineer microbes with desirable traits and devise systems for culturing them and isolating the products they make.<o:p></o:p></span></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <b><span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">Microbial physiology<o:p></o:p></span></b></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px; text-indent: 36pt;"> <span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">Microbial physiology is concerned with studying the synthesis of antibiotics and toxins, microbial energy production, the ways in which microorganisms survive harsh environmental conditions, microbial nitrogen fixation, and the effects of chemical and physical agents on microbial growth and survival.<o:p></o:p></span></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px;"> <b><span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">Microbial genetics and molecular biology<o:p></o:p></span></b></div> <div class="MsoNormal" style="background-color: #1c1c1c; color: #cccccc; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14.85px; line-height: 22.275px; text-indent: 36pt;"> <span style="font-family: "times new roman", serif; font-size: 12pt; line-height: 24px;">Microbial genetics and molecular biology focus on the nature of genetic information and how it regulates the development and function of cells and organisms.
