We have used a standardized disk diffusion procedure to test the susceptibility of 892 isolates of Neisseria gonorrhoeae to six antibiotics. The disk diffusion test described is a modification of the disk test of Bauer, Kirby, Sherris, and Turck, which is widely used for susceptibility testing of fast-growing, aerobic pathogens. With all six antibiotics(More)
The sensitivities of gonococcal isolates to six antibiotics were determined for gonococci isolated in Philadelphia in 1972. The degree of association between susceptibilities to any two antibiotics was determined (coefficient of correlation). The correlation between penicillin and tetracycline (r = 0.75) was almost as good as that between two penicillins,(More)
