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

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

The following show expected colony appearances and morphologies (shapes) of Escherichia coli and Staphylococcus aureus. Note characteristics such as edges‚ color‚ and whether the colonies are rough or smooth in texture. For colony appearances of E. coli and S. aureus‚ scientists often describe what they look like on agar. This is not the microscopic view (for example‚ as with a slide) but a “naked eye” view of how the bacterial colonies look while growing on a medium. (This is one type of culture

The culture did appear homogenous throughout the testing period and is currently retained by Northern Michigan University’s department of Microbiology. We suggest that culture 16 is an example of Escherichia coli. Background: Techniques
