Plant-Microbe Interactions and Immunity

THE MYCOBIOTA PRESENT IN NATURAL HABITATS OF HISTOPLASMA CAPSULATUM WAS DETERMINED IN SAMPLES OF BAT GUANO, POULTRY DROPPINGS, AND INTESTINAL CONTENTS OF BATS. THE FOLLOWING FUNGI WERE ISOLATED: 1) FROM BAT GUANO: THE ASCOMYCETES APHANOASCUS FULVESCENS, GYMNASCELLA CITRINA, GYMNOASCUS DANKALIENSIS, AND CHAETOMIDIUM FIMETI; THE MITOSPORIC FUNGI ASPERGILLUS FLAVO-FURCATIS, A. TERREUS, A. TERREUS VAR. AUREUS, PENICILLIUM SPP., MALBRANCHEA AURANTIACA, AND SPOROTHRIX SP.; AND THE YEASTS CANDIDA CATENULATA, C. CIFERRII, C. FAMATA VAR. FLARERI, C. GUILLIERMONDII VAR. GUILLIERMONDII, AND RHODOTORULA SPP. 2) FROM POULTRY DROPPINGS: THE COELOMYCETE PHOMA SP.; AND THE YEASTS C. ALBICANS, C. CATENULATA, C. CIFERRII, C. FAMATA VAR. FLARERI, C. TROPICALIS, CRYPTOCOCCUS ALBIDUS, TRICHOSPORON MONILIIFORME, AND TRICHOSPORON SPP. 3) FROM THE INTESTINAL CONTENTS OF INSECTIVOROUS, HEMATOPHAGOUS, NECTARIVOROUS, AND FRUGIVOROUS BATS: CH. FIMETI; THE MITOSPORIC FUNGI ASPERGILLUS CANDIDUS, A. FL AVO-FURCATIS, A. SULPHUREUS, A. SYDOWII, A. TERREUS, A. VERSICOLOR, ASPERGILLUS SP., M. AURANTIACA, GLIOMASTIX MURORUM, AND SCOPULARIOPSIS SP.; AND C. FAMATA VAR. FLARERI, C. LIPOLYTICA, CR. ALBIDUS, AND TRICHOSPORON SPP. MOST OF THE SPECIES FOUND ARE FIRST RECORDS FOR THESE SUBSTRATA AND ENVIRONMENTS IN MEXICO. THE COEXISTENCE WITH H. CAPSULATUM WAS DEMONSTRATED BY HIGH SPECIFIC ANTIBODY TITERS IN ELISA SEROLOGICAL METHOD, USING SERA FROM BALB/C MICE PREVIOUSLY INOCULATED WITH THE SUPERNATANT OF THE DIFFERENT SAMPLES STUDIED.
