The Case for Adopting the “Species Complex” Nomenclature for the Etiologic Agents of Cryptococcosis
ABSTRACT Cryptococcosis is a potentially lethal disease of humans/animals caused by Cryptococcus neoformans and Cryptococcus gattii. Distinction between the two species is based on phenotypic and genotypic characteristics. Recently, it was proposed that C. neoformans be divided into two species and...
