Isolation and characterization of a Paracoccidioides brasiliensis strain from a dogfood probably contaminated with soil in Uberlândia, Brazil

We report the isolation of a strain of Paracoccidioides brasiliensis from a dogfood, probably contaminated with soil, in a Brazilian city. The fungus was isolated on appropriate culture media, and when inoculated into a guinea-pig testis produced orchitis with abundant fungal elements. Histopathology of sections of the testicle showed an inflammatory reaction with P. brasiliensis inside monocytes. Immunological identification confirmed the identity of the isolate.
