Isolation, molecular identification, and phylogenetic evaluation of Cryptococcus neoformans isolated from pigeon lofts, Psittaciformes, and Passeriformes in Ahvaz, Iran.

Cryptococcus neoformans, the main pathogen in immunocompromised patients, is a ubiquitous free-living fungus that can be isolated from avian excreta, soils, and plant material. This study was carried out to determine the infection rate of pigeon lofts, Passeriformes, and Psittaciformes in Ahvaz, the capital of Khuzestan province in Iran and to determine varieties of Cryptococcus neoformans (C. neoformans).
