Última Bacillus subtilis induces morphological changes in Fonsecaea pedrosoi in vitro resulting in more resistant fungal forms in vivo J. Venom. Anim. Toxins incl. Trop. Dis. Machado,AP; Anzai,M; Fischman,O. Interactions among microorganisms may be the cause of morphological modifications, particularly in fungal cells. The aim of this work was to examine the changes that occur in cells of the fungus Fonsecaea pedrosoi after in vitro co-culturing with Bacillus subtilis and to explore the results of this interaction in vivo in an experimental murine infection. B. subtilis strain was inoculated into a 15-day pure culture of F. pedrosoi. In vitro, after 48 hours of co-culturing, the fungal cells were roundish. The secretion of fungal dark pigments and production of terminal chlamydoconidia were observed in hyphae after one week. In the in vivo study, two animal groups of 30 BALB/c mice each were employed. One group was inoculated intraperitoneally with hyphal...

Ano: 2010 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1678-91992010000400009 Experimental murine chromoblastomycosis obtained from Fonsecaea pedrosoi isolate cultured for a long periodt J. Venom. Anim. Toxins incl. Trop. Dis. Machado,AP; Freymuller,E; Fischman,O. The present study aimed to describe F. pedrosoi propagules capable of causing chronic murine disease. Several changes in F. pedrosoi hyphae were identified in fungal cells cultured for a long period. Optical microscopy found many rounded cells with double-rigid melanin-rich walls. Terminal and intercalary chlamydoconidia were also frequently observed. Analyses of images from transmission electron microscopy (TEM) revealed several cells with walls composed of at least three layers and an outer layer enriched with melanin. Two groups of twenty BALB/c mice were subcutaneously infected in their footpads with F. pedrosoi cells at an inoculum concentration of approximately 1 x 10(4) cells/mL. In one group, long-term cultured F. pedrosoi cells were inoculated in... Tipo: Info:eu-repo/semantics/article Palavras-chave: Fonsecaea pedrosoi; Experimental chromoblastomycosis; Sclerotic cells.
