本邦におけるアフリカ型PPNGの検出

Abstract

The Plasmid DNA patterns of 22 penicillinase-producing Neisseria gonorrhoeae (PPNG) strains isolated from male patients with gonococcal urethritis in 1988 at Tokyo Metropolitan Taito Hospital were determined. The 3.3 megadalton plasmid, the so called the African type plasmid, was present in 3 isolates out of 22 PPNGs, all of which occurred with a conjugative 24.5 megadalton plasmid. 4.4 megadalton plasmid was present in 19 isolates out of 22 PPNGs, 5 of which occurred with a conjugative 24.5 megadalton plasmid. The infective sources of the 3 cases of the African type PPNGs were found as 1 from philippines and 2 from prostitutes, so called Soap Land Girl in Japan. And they suggests that the African type PPNGs are already common in Japan.
