ABSTRACT
Cryptococcus neoformans and Cryptococcus gattii are important agents of meningoencephalitis in humans in the city of Belém. This clinical data suggests that the region may be a highly endemic area for the pathogenic Cryptococcus species within the state of Pará (PA), Northern Brazil. Preliminary analysis of 11 environmental samples from the city of Belém showed two positive locations, including a hollow of a kassod tree (Senna siamea) colonized simultaneously by C. gattii molecular type VGII and C. neoformans molecular type VNI, and a birdcage in a commercial aviary positive for C. neoformans, molecular type VNI. This is the first evidence of an environmental occurrence of molecular types VNI and VGII in PA.

Vinte cepas de Coccidioides immitis foram avaliadas.Cinco das 20 cepas preservadas sob óleo mineral mantiveram-se viáveis, todas as 5 subculturas preservadas em água permaneceram viáveis e nenhuma das 13 subculturas mantidas em solo foi viável. Um produto de PCR de 519 pb do gene csa confirmou a identidade das cepas.
