Chocolate agar is essentially the same as blood agar except that during preparation the red blood cells are lysed when added to molten agar base. 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. The feedback you provide will help us show you more relevant content in the future.

L. pneumophila is a Gram-negative, non-encapsulated, aerobic bacillus with a single, polar flagellum often characterized as being a coccobacillus. It is used primarily to isolate fastidious organisms like H. influenza. When growing Neisseria meningitidis, one usually starts with a normally sterile body fluid (blood or CSF), so a plain chocolate agar is used. Why does gonorrhea not grow on blood agar? Colorless colonies, medium is slightly yellow due to the increased pH resulting from bacterial digestion of peptone in the medium. How long does it take to reheat shepherds pie in the microwave?

Do not use the first subculture from a frozen culture; subculture these isolates again before using to prepare the inoculum. The name is derived from the fact that the lysis of RBC gives the medium a chocolate-brown color. The added supplements provide the necessary X factor (from Haemoglobin) and V factor (from Growth Supplement) required by the fastidious organisms. Chocolate agar is used for growing fastidious respiratory bacteria, such as Haemophilus influenzae and Neisseria meningitidis. The GISP Coordinator and Manager in ESB, DSTDP, NCHSTP, CDC should be notified within one working day by telephone or by e-mail of any isolate(s) identified to have a high MIC; the GISP Coordinator or Manager will then immediately communicate the results to the Sentinel Site and the pertinent local and/or state STD programs. Neisseria gonorrhoeae is a fastidious bacterium, difficult to cultivate in liquid medium due to susceptibility to pH and divalent cation concentrations and a tendency to autolysis.
