title: [Cytological mechanisms of the development of mucosal candidiasis after exposure to a steroid aerosol preparation].
abstract: Mucosal candidosis was induced in CBA mice by intraoral inoculation following treatment with corticosteroid-containing aerosol (beclomethasone dipropionate). Histologically, in hormone treated mice the adherence of the pathogen to the mucosal surface was found during the first hours after inoculation. This is followed by the formation of the germ tubes and invasion in the epithelial layer. Pseudomycelial invasion in the malpighian layer is accompanied by the leukocyte response that limits the further spread of the fungal cells. In intact mice, the inoculation is not followed by the effective attachment of the fungal cells to the mucosal surface and induction of mycotic lesions. In vitro experiments have demonstrated the enhanced adherence of fungal blastospores to the epithelial cells of the hormone treated animals, that appears to be one of the mechanisms in the pathogenesis of candidosis in these animals.
