Neisseria gonorrhoeae is one of the causatives of sexually transmitted diseases, and it is a fastidious organism. Thayer-Martin agar is a chocolate agar plate (heated blood agar) containing nutrients and antimicrobials (vancomycin, colistin, nystatin, and trimethoprim). Chocolate agar with bacitracin - It is a selective medium for the improvement of primary isolation of H. influenzae from a specimen that has a mixed flora of bacteria and fungi. 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. Chocolate Agar Rev: May2016 Page 1 of 3 P.O. Why do the instructions for the growth of Neisseria gonorrhoeae recommend a CO 2-enriched atmosphere? Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with SunAgri and INRAE in Avignon between 2019 and 2022.

Chocolate Agar is an enriched general- purpose medium that supports the growth of most fastidious and non-fastidious organisms. There are anaerobic microorganisms that are aero-tolerant and they usually grow well in anaerobic conditions but not so in air or carbon dioxide. The manner of preparation is the difference between them as chocolate agar requires lysis of the red blood cells when added to the molten agar base. Cool at 45C -50C. This organism is oxidase-positive, and growth is best obtained on Chocolate Agar or . The heat inactivates enzymes that could otherwise degrade NAD. As a result, the cell lysis releases intracellular nutrients such as hemoglobin, hemin (X factor), and the coenzyme nicotinamide adenine dinucleotide (NAD or V factor) into the agar which is utilized by fastidious bacteria. Precipitated hemoglobin may appear as dark spots on or in the media and does not affect the performance of the media. Good recovery of gonococci is possible if swabs are cultured within 12 hours of collection. Use a separate sheet to record the results for each antibiotic tested and record the growth for each isolate on each antibiotic concentration tested.
