Cryptococcus neoformans shows a remarkable genotypic diversity in Brazil.

The genotypic diversity of Brazilian Cryptococcus neoformans strains was analyzed. The majority of the samples were alphaA (65%), followed by alphaB (17.5%), alphaD (9%), alphaAaD hybrids (5%), and alphaC (3.5%). A considerable genotypic diversity occurred within C. neoformans var. grubii, and a new amplified fragment length polymorphism genotype, 1B, was recognized.
