Chocolate agar, a differential medium for gram-positive cocci. Principle of Chocolate Agar As Neisseria species are highly sensitive to toxic substances such as fatty acids, hence the addition of cornstarch helps neutralize possible toxic metabolites, while potassium phosphate helps maintain a uniform pH during growth. Disseminated infections commonly manifest as septic arthritis, tenosynovitis, pustules in the skin, endocarditis, and meningitis. Inoculate each plate of the set of antibiotic containing media plus a plate of GCS (as a control to determine that all isolates grew). It is used frequently in clinical laboratories. Two species of Neisseria cause disease in humans; Neisseria meningitidis and Neisseria gonorrhoeae. It needs to be used correctly to facilitate the growth of most pathogens in clinical infections.
