Answer #1

1- selective media

contain susbtance that inhibit all but a few type of bacteria and facilitate the isolation of a particular species. These media are used to isolate a particular bacteria specimen where mixed bacterial flora is expected.

2- diffrential media - when media contain subastancw differing characterstic of bacteria it is called differetial media .

    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.
