Because gonococci must often be isolated from sites that contain large numbers of normal flora (e.g. ,genital tract,upper respiratory tract),selective media have been developed to facilitate their recovery.The first of these was the Thayer-Martin medium,a chocolate agar with an enrichment supplement (IsoVitaleX)and the antimicrobials colistin (to inhibit gram-negative bacilli),nystatin (to inhibit yeast),and vancomycin (to inhibit gram-positive bacteria).This original medium was subsequently modified to include trimethoprim (to inhibit swarming Proteus),and its name was changed to MTM medium.ML medium is similar to MTM except that anisomycin,an antifungal agent,is substituted for nystatin,and the concentration of vancomycin is increased.A transparent medium containing lysed horse blood,horse plasma,yeast dialysate,and the same antibiotics as MTM,called NYC medium,has also been used.
