OBJECTIVE: To determine the prevalence of histoplasmosis and paracoccidiomycosis in Upata, a city in Bolivar state, Venezuela. METHODS: Cutaneous tests on 397 volunteers, 204 with histoplasmine and 193 with paracoccidioidine. Epidemiological data were collected in a protocol sheet. Readings were performed at 24 and 48 h post-injection, by the same observer, and a positive reaction was defined as hardened papule of 5 mm or more. RESULTS: Histoplasmine tests were positive in 19.6% and 34.0% at 24 and 48 h after antigens injection with a significant increase of reactivity (P=0.0019). Paracoccidiodine tests were positive in 11.3% and 19.7% at 24 and 48 h respectively and this difference was also significant (P=0.004). Risk factors which could explain these levels of reactivity could not be clearly identified. Cultures and animal inoculation from soil samples for fungus isolation were negative. CONCLUSIONS: Paracoccidioidomycoses and histoplasmosis are endemic in Upata.
