Mixed infection by Histoplasma capsulatum isolates with different mating types in Brazilian AIDS-patients.

ABSTRACT: Mixed infection by Histoplasma capsulatum isolates with different mating types, in AIDS-patients are described in this study. Morphological, mating type-specific PCR assay and multilocus sequencing type analysis of H. capsulatum isolates recovered from two Brazilian AIDS-patients were performed. Five H. capsulatum isolates were recovered at different times from the two patients. Three isolates were obtained from bone marrow (day 1 - CE0411) and buffy coat cultures (day 1 - CE0311; day 2 - CE0511) of patient 1, and two isolates were isolated from buffy coat cultures (day 3 - CE2813; day 12 - CE2513) of patient 2. The mycelial colonies depicted different textures and pigmentation features. Dimorphic conversion to the yeast-phase in ML-Gema medium was achieved in all isolates. MAT1-1 idiomorp
