ISOLATION OF A PENICILLINASE PRODUCING STRAIN OF NEISSERIA GONORRHOEAE

Abstract

A gram-negative diplococcus with the qualifications of a gonococcus was isolated from the urethra of a male infected with gonorrhoea in the Far East. The strain was resistant to penicillin G and ampicillin, as judged by the paper disc sensitivity test. The resistance was caused by a great production of penicillinase which not only acted on penicillin G and ampicillin, but also on methicillin and partly on cephalosporin.
