[The evaluation of ketoconazole in mice inoculated with Paracoccidioides brasiliensis by liver and spleen histopathology and by the intradermal paracoccidioidin reaction].

Male albino mice were inoculated intravenously with 0.5 x 10(7) viable yeast forms of P. brasiliensis (strain 2052). These animals were treated with two doses of ketoconazole (50 and 100 mg/kg) during fifty days and the sacrificed. We studied the presence of P. brasiliensis, the inflammatory granulomatous response of liver and spleen and the anti P. brasiliensis delayed hypersensitivity response measured by the footpad test after 48 hours. It was observed that: 1. animals infected and treated with ketoconazole showed reduction in the number of fungi in the organs studied; 2. there was no difference in the number of granulomas among animals treated and non-treated; 3. the cutaneous delayed tests intensity was similar in all animals.
