...Microbiology Mid Term Review What contribution did these dudes make to science and what type of experiments were involved in the discoveries they made? Louis Pasteur- Heat pasteurization- 1st vaccine for rabies. Found alcohol only produced in wine if yeast was present. “Swan necked” flasks experiment for spontaneous generation. Robert Koch- Studied anthrax, Koch’s postulates (germ theory) studied and awarded for TB research. Anton van Leewenhoek- Made the 1st lens to observe living microorganisms. The lens magnified up to 300x and were free of distortion. Edward Jenner- Studied small pox. Came up with the first vaccine for smallpox. Alexander Fleming- Discovered lysozyme (an enzyme) was found in tears, saliva, and sweat could kill bacteria. What issues and types of instruments are involved in visualizing bacteria and viruses with a compound light microscope? Reflection- transmission-absorption with florescence-refraction. Condenser-is a lens that serves to concentrate light from the illumination source that is in turn focused through the object and magnified by the objective lens. iris diaphragm-regulates the amount of light on the specimen. objective lenses- magnifies ranges from 10x to 40x, ocular lenses. stage- supports the slide for viewing. focusing knobs-moves the stage up and down for focusing. total magnification- take the power of the objective (4X, 10X, 40x) and multiply by the power of the eyepiece, usually 10X. What are the differences...

...Section A: Basic Microbiology 1 SCOPE AND HISTORICAL DEVELOPMENTS IN MICROBIOLOGY “Science contributes to our culture in many ways, as a creative intellectual activity in its own right, as a light which has served to illuminate man’s place in the uni-verse, and as the source of understanding of man’s own nature” —John F. Kennedy (1917–63) The President of America The bacterium Escherichia coli INTRODUCTION AND SCOPE MICROBIOLOGY is a specialized area of biology (Gr. bios-life+ logos-to study) that concerns with the study of microbes ordinarily too small to be seen without magnification. Microorganisms are microscopic (Gr. mikros-small+ scopein-to see) and independently living cells that, like humans, live in communities. Microorganisms include a large and diverse group of microscopic organisms that exist as single cell or cell clusters (e.g., bacteria, archaea, fungi, algae, protozoa and helminths) and the viruses, which are microscopic but not cellular. While bacteria and archaea are classed as prokaryotes (Gr. pro-before+ karyon-nucleus) the fungi, algae, protozoa and helminths are eukaryotes (Gr. eu-true or good+ karyon-nucleus). Microorganisms are present everywhere on earth, which includes humans, animals, plants and other living creatures, soil,water and atmosphere. Microorganisms are relevant to all of our lives in a multitude of ways. Sometimes, the influence of microorganisms on human life is beneficial, whereas at other times, it is detrimental. For example...

...Research Proposal MSc Part 2 Sem 3 CERTIFICATE This is to certify that Mr. Akshay L. Shettigar has satisfactorily completed his proposal entitled “Biodegradation study of Triphenylmethane dye Crystal Violet by bacterium isolated from textile effluent.” for the year 2014-2015. Signature of the Project guide Signature of the Examiner (Prof. Mrs Radhika Birmole) Date and college Stamp Signature of the H.O.D. Proposal (i) Project Title: Biodegradation study of Triphenylmethane dye Crystal Violet by bacterium isolated from textile effluent. (ii) Introduction: Synthetic dyes are extensively used in textile dyeing, paper printing, colour photography, pharmaceutical, cosmetic and other industries [1]. Over ten thousand different dyes with an annual production of over 7x105 metric tons worldwide are commercially available [2]. 2% of dyes that are produced are discharged directly in aqueous effluent and 10% are subsequently lost during the textile coloration process [3]. Major classes of synthetic dyes include azo, triphenylmethane and anthraquinone dyes, some of them are known to be very toxic and mutagenic to living organism. With the increasing use of wide variety of dyes pollution by dye-waste water is becoming increasingly alarming. Colour removal, in particular, has recently become a major scientific interest. Although several...

...Preface A well-developed knowledge of clinical microbiology is critical for the practicing physician in any medical field. Bacteria, viruses, and protozoans have no respect for the distinction between ophthalmology, pediatrics, trauma surgery, or geriatric medicine. As a physician you will be faced daily with the concepts of microbial disease and antimicrobial therapy. Microbiology is one of the few courses where much of the "minutia" is regularly used by the practicing physician. This book attempts to facilitate the learning of microbiology by presenting the information in a clear and entertaining manner brimming with memory aids. Our approach has been to: 4) Create a conceptual, organized approach to the organisms studied so the student relies less on memory and more on logical pathophysiology. The text has been updated to include current information on rapidly developing topics, such as HIV and AIDS (vaccine efforts and all the new anti-HIV medications), Ebola virus, Hantavirus, E. coli outbreaks, Mad Cow Disease, and brand-new antimicrobial antibiotics. The mnemonics and cartoons in this book do not intend disrespect for any particular patient population or racial or ethnic group but are solely presented as memory devices to assist in the learning of a complex and important medical subject. We welcome suggestions for future editions. 1) Write in a conversational style for rapid assimilation. 2) Include numerous figures serving as "visual memory tools" and summary charts...
