H1N1: The Sneaky Killer I chose to write my topic paper on the H1N1 virus. This virus has interested me since its reemergence in 2009. Its ability to change and adapt each time it shows up again attracted my attention. I hope to inform people about the virus along with the symptoms and how to go about avoiding it if you can‚ or treating it if you have it. This pandemic is avoidable through a simple vaccine that can be taken as a shot or as a nasal spray. Overall I find the H1N1 virus to be interesting

Microbiology Coursework: Bacillus cereus After investigation following on outbreak of food poisoning at a pizza restaurant‚ it was found that all suffers had consumed a portion of side salad from the self-service salad bar alongside their main dish. Subsequently‚ this was further traced to a rice salad. Environmental Health Officers investigating this outbreak suspected it may have been caused by Bacillus cereus (B. cereus). The presence of large numbers of B. cereus in a food is indicative

Microbiology in the News: Fecal Transplants Zimmer’s article on fecal transplants (2016)‚ discusses how the effectiveness of transporting healthy stool to sick individuals has led to a series of unanswered questions and beliefs. For years scientists were unsuccessful in finding a use for this type of treatment. The breakthrough came about during a trial experiment using the procedure to treat a serious bacterial infection; Clostridium difficile. Clostridium difficile is a bacterium that causes

explained through science. I have always been fascinated to know how things work and why or how they happen. That is why microbiology is perfect for me. I like finding out how or why something can happen and I can do that if I go into the field of science. I have been looking into colleges and professions recently and I have become very interested in microbiology. Microbiology is the study of microorganisms. Microbiologists try to understand the organisms and how they interact with their

Escherichia coli Microbiology Lab NAS 185-14L Introduction In this lab experiment we did several test to determine what our unknown bacteria was. To determine this we recorded the results of how the bacteria reacted to different media. Depending on the results of each test we could narrow down the different bacteria to determine what our unknown is. This experiment will also determine if our bacteria is a fermenter of sugars and if it is catalase positive. If the bacteria is
