Neisseria gonorrhoeae are the most fastidious of the Neisseria species, require complex growth media and are highly susceptible to toxic substnces (e.g., fatty acids). Sexual transmission: Acquired during unprotected sex with infected partner. H. influenzaeis not able to grow on sheep blood agar. Two species, N. gonorrhoeae (the gonococcus) and N. meningitidis (the meningococcus), are important human pathogens. It causes disease only in humans. It is a variant of the blood agar plate, containing red blood cells that have been lysed by slowly heating to 80C. N. gonorrhoeae is the causative agent of gonorrhea (also called "The Clap") and is transmitted via sexual contact. The composition of chocolate agar is the same as the blood agar and the only difference is while preparing Chocolate agar, the red blood cells are lysed changing the medium color to chocolate brown.

If there is profuse urethral discharge in male, it can be collected without inserting the swab. This will generally require maintenance of isolates from the current year and the previous year. Precipitated hemoglobin may look as dark spots on the media but it does not have any impact on the medias performance. Gonococci cause localized infections, usually in the genital tract, and disseminated infections. When isolates are requested by CDC for further characterization, triplicate copies of each requested isolate should be shipped to CASPIR, CDC. For the organism to grow, various nutrients are added such as casein and animal tissue, which serves as amino acids, nitrogenous nutrients, and other vital elements for the organisms growth. As a sterility test, incubate an uninoculated plate for 48 hours at 35-37C with 5% CO. Store at 2-8C and away from direct light.
