INTRODUCTION Total Viable Count is a quantitative idea about the presence of microorganisms such as bacteria‚ yeast and mold in a sample. It counts the number of colonies produced by a very dilute suspension of bacteria on an agar plate and to observe the differential staining behaviour of the living bacteria. This involves counting the colonies produced by viable cells under favourable growth conditions. Some techniques needed before the viable count‚ like pour plate method‚ spread plate method

MICROBIOLOGY STUDY QUESTI0NS - EXAM 1 1. Briefly discuss the theory of spontaneous generation. What scientific evidence was presented to disprove the theory? Spontaneous generation- theory (until second half of 19th century) that some forms of life can arise spontaneously from nonliving matter‚ i.e. maggots from corpses Redi (1668)- demonstrated maggots do not arise from decaying meat by filling two jars with decaying meat (one sealed‚ one unsealed). Unsealed jar developed larvae and sealed did

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

Microbiology is involved in many aspects of human daily life. The food eaten to the showerheads in the bathroom contain thousands of microbes. Microbiology is evident in our lives and it is reported through various media. News reports have articles about microbes just like a recent article from Times Magazine titled Overcoming Obesity by Alex Park. Park featured article is about the problem of obesity in America and how different scientists are thinking of new manners to combat this epidemic

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
