Cotrimoxazole enhances the in vitro susceptibility of Coccidioides posadasii to antifungals.
The aim of the present study was to evaluate the effect of cotrimoxazole on the in vitro susceptibility of Coccidioides posadasii strains to antifungals. A total of 18 strains of C. posadasii isolated in Brazil were evaluated in this study. The assays were performed in accordance with the Clinical and Laboratory Standards Institute guidelines and the combinations were tested using the checkerbo...
متن کاملCoccidioides posadasii produces melanin in vitro and during infection.
Using techniques developed to study melanization in other fungi, we demonstrate that Coccidioides posadasii arthroconidia, spherules, and endospores produce melanin or melanin-like compounds in vitro and tissue forms synthesize pigment in vivo. Since melanin is an important virulence factor in other pathogenic fungi, it may affect the pathogenesis of coccidioidomycosis.
متن کاملCoccidioides posadasii Infection in Bats, Brazil
To analyze the eco-epidemiologic aspects of Histoplasma capsulatum in Brazil, we tested 83 bats for this fungus. Although H. capsulatum was not isolated, Coccidioides posadasii was recovered from Carollia perspicillata bat lungs. Immunologic studies detected coccidioidal antibodies and antigens in Glossophaga soricina and Desmodus rotundus bats.
متن کاملSusceptibility of TLR4-defective C3H/HeJ mice to Coccidioides posadasii infection.
Coccidioides posadasii is one of the two fungal pathogens that cause coccidioidomycosis. The inhalation of air-borne arthroconidia leads to the formation of endospore-forming spherules in the lungs and pulmonary infection. In severe condition, the endospores are disseminated to other non-pulmonary organs in the body. The Toll-like receptors (TLR) expressed by a number of immune and non-immune c...
متن کاملGenetic diversity of Coccidioides posadasii from Brazil.
Studies of the genetic variation within populations of Coccidioides posadasii are scarce, especially for those recovered from South America. Understanding the distribution of genotypes among populations is important for epidemiological surveillance. This study evaluated the genetic diversity of 18 Brazilian strains of C. posadasii through the sequencing of the 18-28S region of nuclear rDNA, as ...
