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

Microbiology and Process Analysis laboratory 25/10/2013 Group 1 Microbiology laboratory Abstract The lab exercises were divided into three different analysis; microscopy‚ soil microbiology and bacterial growth. The main aim of laboratory work with Escherichia coli and soil sample was to introduce students to bacterial growth in pure culture and soil microbial flora. The experiment of bacterial growth in pure culture using optical density

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
