title: A new improved medium for antibiotic susceptibility testing of N. gonorrhoeae.
abstract: In order to assess the effectiveness of the agar plate dilution method for susceptibility testing of N. gonorrhoeae, different media were used. A total of 2,210 N. gonorrhoeae strains were tested on eight different media. The best results were obtained with G.C. base medium (Difco) enriched with 0.1% Isovitalex and 1.5% lysed horse blood and by using a bacterial inoculum with the opacity of No. 1 McFarland nephelometric standard. This medium yielded constant results and 98.6% of the N. gonorrhoeae strains grew well on the control plates.
