Treatment of ordinary and penicillinase-producing strains of Neisseria gonorrhoeae in Mexico City.

Since being recognized in 1976 and 1983, respectively, penicillinase-producing strains of Neisseria gonorrhoeae (PPNG) and chromosomally mediated resistance (CMRNG) have attained a worldwide distribution. The high endemicity of both types of resistance in some regions precludes the continued routine use of procaine penicillin (APPG) as treatment for gonorrhea. In this study, we have evaluated 72/216 men with uncomplicated gonococcal urethritis at the venereal clinic in Mexico City.
