Abstract
The minimal inhibitory concentration (MIC) of twelve antibiotics was determined by the method of dilution in agar for 50 non penicillinase-producing and 15 penicillinase-producing Neisseria gonorrhoeae (PPNG) strains. The commonly used antibiotics are active in vitro against all the strains. For the non PPNG stains, no difference was observed between the MICs with a previous investigation, in 1980. New quinolones are highly active against all the strains tested but two, with decreased sensitivity. Since 1980, 16 PPNG strains were isolated (2.2%) and analysed for plasmid content. Asian type plasmid (7.4 kb) was present in 9 strains and african type (5.3 kb) in 7 strains. The conjugative plasmid (39 kb) was present in 5 strains and the cryptic plasmid (4.4 kb) in all the strains.
