Detection of the gp43 gene and (1-3)-beta-D-glucan of Paracoccidioides brasiliensis in the blood of experimentally infected mice.

Paracoccidioidomycosis (PCM) is a deep mycosis caused by the thermo-dependent dimorphic fungus Paracoccidioides brasiliensis and is prevalent in Latin American countries. Diagnosis of PCM is sometimes difficult outside the endemic countries, thus a rapid and conclusive method for diagnosis of PCM has been anticipated. We compared the sensitivities of a nested PCR method for detecting the gp43 gene and a commercial kit for detecting (1-3)-beta-D-glucan in the blood of experimentally infected mice.
