Fatal Cryptococcus gattii genotype AFLP6/VGII infection in a HIV-negative patient: case report and a literature review.

Cryptococcus gattii, a species belonging to the Cryptococcus complex which occurs endemically in tropical and subtropical regions, has been reported as a causative agent of cryptococcosis in healthy individuals. We report a case of meningitis in HIV-negative patient from Cuiaba, MT, in the Midwestern region of Brazil. Cryptococcus gattii AFLP6/VGII was isolated from cerebrospinal fluid and molecular typing was performed by URA5-RFLP. The in vitro susceptibility profile was determined using the standard method according to the document M27A3, CLSI 2008. C. gattii AFLP6/VGII was shown to be susceptible to the antifungals tested. Treatment with 0.8 mg/kg of amphotericin B was initiated; however, the patient died 2 days after the onset of therapy.
