The aim of the present study was to compare the male lineages present in two distinct Brazilian(More)
Phaeohyphomycosis is a rare, slowly progressive infection caused by a heterogeneous group of imperfect black or dematiaceous fungi that are found in plants and soil, and contain a cytoplasmic melanin-like pigment, which appears to have aetiological significance by decreasing the susceptibility of these organisms to antifungal agents. A commonly recognised(More)
Reference broth microdilution protocols for the antifungal susceptibility testing (AST) of yeasts are available, but routine AST relies more on simpler alternatives. In this work, the Etest and a novel flow cytometry (FC) method were compared to the Clinical Laboratory Standards Institute (CLSI) protocol M27-A3. Caspofungin and anidulafungin were tested(More)
Avaliámos a incidência dos dermatófitos isolados no nosso hospital, nos anos de 1997 a 2000, e a sua correlação com a localização anatómica e idade. Trichophyton rubrum foi a espécie predominante em todas as localizações ana-tómicas, excluindo o couro cabeludo, seguido de Microsporum canis, principal agente da tinea capitis. Todas as dermatofitias, excepto(More)
We report an atypical case of Rhodotorula mucilaginosa fungemia coexisting with pleural tuberculosis, in an immunocompetent host. The patient was an inhaled drug abuser and worked in a fruit market. The diagnosis of Rhodotorula mucilaginosa infection was established by the isolation of the yeast in two blood cultures followed by a good response to(More)
Cryptococcal infection has been increasing among immunosuppressed population. We report three cases of Cryptococcus neoformans infection in immunosuppressed patients - two renal transplanted and one with lupus nephritis. Early infection (<3months) was diagnosed in two - an allograft Cryptococcus infection and a central nervous system involvement. The third,(More)
