How is chocolate media different than blood agar media?
1.Blood agar contains more bacterial inhibitors to previous growth of fastidious organism.
2.blood agar has intact red blood cells
3.chocolate allows for the determination of lysis,allowing it be differential media.
4.chocolate is primarily used for enteric organisms while blood is used for fastidious organism.

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...

NEISSERIA EXPERIMENT MICROBIOLOGY LAB (Revised March 2016) Background There are two main pathogens in the genus Neisseria: N.gonorrhoeae and N meningitidis, along with many species which are normal flora for mucus membranes like the nasopharynx, vagina, urogenital tract, etc. In order to diagnose gonorrhea in a male, a Gram stain of the urethral discharge should reveal Gram negative diplococci and many white blood cells. This is considered sufficient grounds to treat for gonorrhea. In a female, diagnosis must be based...
