Bring to boil and autoclave for about 15 minutes at 12 pounds pressure at a 21 degrees Celsius. You may also wish to inoculated a GCS plate between each set of antibiotic-containing medium to ensure against carry-over of antimicrobial agents from one medium to another; these plates also allow for monitoring for contamination of the inocula during the inoculation process. For azithromycin, isolates should be tested for growth on medium containing azithromycin at concentrations ranging from two dilutions below the initial MIC to sufficient concentrations above the initial MIC to obtain an endpoint MIC. It is aerobic and unable to hydrolyse gelatin or produce urease. Chocolate Agar Plate (CHOC or CA) o Contains lysed RBCs (slow heating to 80C) o Used for growing fastidious bacteria (e., Haemophilus influenzae) . As Neisseria gonorrhoeae is a fastidious organism and requires additional nutrients for growth, chocolate agar ( heated blood agar) ensures good growth of colonies. Such isolates also should be shipped rapidly in triplicate to CASPIR, CDC; laboratory personnel should not wait until the request lists arrive from CDC to ship these isolates. It is the lysis of the red blood cells that give the medium its chocolate-brown color; hence, the reason for the name chocolate agar. Clinical Significance Gonorrhea is a sexually transmitted disease caused by N. gonorrhoeae and is one of the most frequently reported infectious diseases in the United States and worldwide. This agar preparation facilitates the growth of Neisseria species while inhibiting the growth of contaminating bacteria and fungi. Chocolate agar with GC base and growth supplement It supports the growth requirements needed to isolate fastidious organisms.
