Penicillinase-producing Neisseria gonorrhoeae isolated in Surabaya.

Although penicillinase-producing strains of Neisseria gonorrhoeae (PPNG) were discovered in 1976 in neighbouring countries, not until 1980 were such strains isolated and identified in Indonesia. In that year PPNG were detected in three male patients with gonococcal urethritis in Surabaya. The minimum inhibitory concentration of penicillin G for all three strains was 12 . 5 microgram/ml.
