[Sensitivity of Neisseria Gonorrhoeae to Spectinomycin]

The susceptibility of 408 strains of N. gonorrhoeae to spectinomycin was determined by an agar plate dilution test. The 401 beta-lactamase-negative and 7 beta-lactamase-positive strains were isolated from patients of the Department of Dermatology, University of Munich, in the years 1977 to 1980. The minimum inhibitory concentrations (MIC) ranged from 2 to 32 micrograms/ml. Only one strain was less susceptible with a MIC of 64 micrograms/ml. A comparison between the isolates of 1977/1978 and 1979/1980 showed no decrease in the susceptibility to spectinomycin.
