[Inquérito epidemiológico com paracoccidioidina e histoplasmina em área agrícola de café em Ibiá, Minas Gerais, Brasil.].

An epidemiological survey in an endemic area for paracoccidioidomycosis in Ibiá town, Minas Gerais state, Brazil was carried out. For this, we used a standard form for each household and intradermal antigens of histoplasmin and paracoccidioidin. Out of 194 individuals, 109(56%) were engaged in the survey showing reactivity of 44% and 49.5% for these antigens respectively. The reactivity to paracoccidioidin was observed in 50% of children below ten years. Individuals who revealed reactivity to paracoccidiodin with prior history of coffee growing activities, and those reporting the grain collection as the main work, showed statistically significant association p = 0.0092, p = 0.0007 and p = 0,01 respectively. These results could suggest that activities related to coffee crops, may favour the transmission of Paracoccidioides brasiliensis, specially among the grain collectors. In addition, the reactivity for histoplasmin antigen, suggest that this region is endemic for both fungi.
