cze Abstract:
[cze][eng] V průběhu studia mikromycetů v jeskyních NP Slovenský kras byly pozorovány žluté kolonie mikroskopických hub na netopýřím guanu. Tuberkulátní konidie této houby připomínají makrokonidie patogenního druhu .i.Histoplasma capsulatum./i.. Testy patogenity i pokus o prokázání teplotního dimorfismu byly negativní. Analýza DNA neprokázala příbuznost s .i.H. capsulatum./i..During studies of micromycetes in several caves (Slovakia - NP Slovak Karst, Czech Republic), white-yellow to yellow coloured microfungal colonies on bat droppings are observed. Tuberculate conidia were estimated in microscopic slides prepared from these colonies. These conidia reminded with their size, shape, surface structures and type of conidiogenesis pathogenous micromycete fungus .i.Histoplasma capsulatum./i.. This micromycete species occurs on bat guano in warmer regions of the world. In Europe, this fungus was recorded from Italian caves and soils and it was also reported from Romania, but without the evidence of thermal dimorphism. After repeteadly isolations, two strains of this fungus were isolated from Slovak caves (Domica Cave and Jasovská Cave). Tests of pathogenity (intranasal and intraperitoneal application to SCID mouses) and of the evidence of thermal dimorphism were negative.
