This study describes antimicrobial susceptibility patterns of Neisseria gon
orrhoeae isolates obtained from female sex workers in Cotonou, Benin. All i
solates were susceptible to spectinomycin, ceftriaxone and ciprofloxacin, a
nd susceptible to moderately susceptible to kanamycin; 9.8% of isolates wer
e resistant to thiamphenicol; 9%, 87.5% and 3.5% were susceptible, moderate
ly susceptible, resistant to trimethoprim-sulfamethoxazole, respectively; 9
4.4% and 99.3% were resistant to penicillin and tetracycline, respectively.
All isolates with a minimal inhibitory concentration of tetracycline of >8
mg/l carried the 'American type' tetM plasmid; 94% and 6% of penicillinase
-producing isolates possessed a 3.2 MDa and a 4.4MDa beta -lactamase plasmi
d, respectively. Surveillance of antimicrobial susceptibility of N. gonorrh
oeae isolates to currently used drugs in Africa should become part of sexua
lly transmitted diseases (STDs) control programmes.
