Background
Ques part 1)
Selective and differential media; EMB and Tsl agar bacill inhabit a wide range of environments. Many are significant pathogens, such a coli, Salmonella, Shigella, but many compose our normal flora and inhabit soil and water. Many gra negative bacilli that inhabit our large intestine are called enterics. Enteric pathogens are the most frequent cause of diarrheal illnesses and have become significant contaminants spread through foo Some can also cause respiratory and urinary infections. Experiment 1: EMB...

Introduction: Selective and differential media are used frequently in Microbiology Pathology Labs to identify a known group of bacteria from a complex mix of other bacteria. The medium is designed to select against as many of the background organisms as possible by using a medium in which they will not grow but the organisms under investigation can grow hence the "Selective" part of the name. Any assayable...

1. Someone new is preparing media for lab and adds buffers to the EMB agar that raise the pH to 7.8. The starting pH of EMB plates should be 6.9 – 7.3. No one is aware of the change. The EMB plates are inoculated for identification of unknown bacteria. After the appropriate incubation time, the results are interpreted. A. Discuss the consequences of the change in starting pH to the interpretation of the results. (The answer is not that no...
