Abstract:
Haemophilus ducreyi was isolated from 59 (52%) of 113 men with a clinical diagnosis of chancroid. The following MIC50 (MIC90) values for H. ducreyi were obtained: erythromycin 0.14 (0.5) micrograms/ml, trimethoprim 0.25 (8.0) micrograms/ml, ceftriaxone 0.009 (0.14) micrograms/ml, and ciprofloxacin 0.007 (0.04) micrograms/ml. These data indicate that all isolates appear to be fully susceptible to erythromycin and the other antimicrobial agents tested, although ciprofloxacin was the most effective antibiotic.
