It is very critical in microbiology to determine the effectiveness of a chemical to either inhibit or kill an organism as it can help cure a disease. If the agent kills the bacteria‚ it is called bactericidal. If the agent inhibits the growth of bacteria‚ it is called bateriostatic. (Fundaments of Microbiology Lab Manual) The purpose of this experiment was to examine the effect different disinfectants and antiseptics‚ which are used to decrease the number of microbes‚ on Escherichia coli and Staphylococcus

has become increasingly more important. The purpose of this study was to identify an unknown bacterium in a controlled laboratory environment over a 5 week period. Utilizing a variety of differential testing and staining methods learned in the microbiology course‚ students were to determine the identity of an assigned unknown organism. Observations were made and recorded each week to narrow down the scope of identification. Data has been presented in the tables‚ charts and drawings herein and

tics Antibiotics Several scientists around the beginning of the 20th Century discovered substances that were toxic to bacteria yet not to the human cell. But it wasn’t until Sir Alexander Flemings own discovery in 1928 that everyone took notice. While washing his equipment‚ Sir Fleming noticed a bit of mold attacking a patch of bacteria. It’s frightening to consider how many more people would have died in the 20th Century if Sir Fleming did not have good eyes. Today‚ some complain that

your presentation of this scientist‚ I was reminded of studying him in my 10th grade biology class many many years ago. In addition to all the contributions you mentioned‚ I believe Luis Pasteur could also be considered the founder of medical microbiology who broke the germ myth. He discovered that diseases are caused by microorganisms and not by spontaneous generation‚ demons or bad karma‚ as many people of his time believed. He found that disease was caused by microorganisms that grew by reproduction
