Susceptibility testings, by means of the agar‐dilution method, were performed on nine antibiotics of 138 non‐PPNG (β‐lactamase‐producing = PPNG) strains, 17 of which originated from Thailand, and 88 PPNG isolates. The gonococcal strains were sero‐grouped by the co‐agglutination method and classified among the sero‐groups W I, W II or W III. Statistically significant differences in antibiotic susceptibility between non‐PPNG strains of the three sero‐groups could be demonstrated with strains belonging to sero‐group W I as the most sensitive and W III isolates as the most resistant. Non‐PPNG strains from Thailand were significantly more resistant than the other non‐PPNG isolates of the same sero‐group. There was, however, no significant difference in resistance between non‐PPNG strains from Thailand and PPNG isolates of the same sero‐group. PPNG strains of sero‐group W I were significantly more sensitive than PPNG strains of sero‐group W II, whereas there was no significant difference between PPNG isolates of sero‐groups W II and W III. Non‐PPNG strains, not from Thailand, of sero‐groups W I and W II were significantly more susceptible to non β‐lactam antibiotics than PPNG strains of corresponding sero‐groups, while no such difference could be demonstrated for non‐PPNG and PPNG isolates of sero‐group W III.
