Abstract
The incidence of chancroid in Rotterdam has increased by more than five-fold during 1977-78. In a retrospective study of 53 patients with chancroid seen at this clinic during this period, the results of smears were positive in 82% and of cultures in 84% (of those for whom cultures had been performed). Symptoms were generally mild. Treatment with co-trimoxazole was highly effective clinically, as confirmed by in-vitro sensitivity studies.
