[Evaluation of secondary bacterial infection's influence on the course of cutaneous leishmaniasis in Corte de Pedra, Bahia].

In order to study the prevalence of secondary bacterial infection in ulcerated lesions and its relationship to the healing process, 84 leishmaniotic patients were evaluated. Diagnosis of the secondary infection was made by bacterial aerobic culture of peripheral tissue specimen of the ulcer. All patients received antimonial therapy during 20 days and washed their ulcers with common soap. Cases were composed mainly of adolescent and adult farmer patients with single lesions. The evaluated ulcers were encountered on legs and feet in 47.6%. Secondary bacterial infection was found in 45/83 (54.2%), and was more frequent in lesions located below the knee. Staphylococcus aureus predominated (89%). The ulcers' healing process, evaluated in 79 patients one month after finishing treatment, was not influenced by the secondary bacterial infection.
