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...
