Abstract Cryptococcosis is among the most prevalent life-threatening mycoses and has a worldwide distribution.Cryptococcus neoformans, the etiological agent of cryptococcosis, has been associated with soil and pigeon DROPpings for more than two decades. Recently Eucalyptus tree is also one of the source of C. neoformans var gattii . Humans may infected by inhaling infectious agents from the environment, which primarily colonize the lung and subsequently invade the central nervous system. The present study was done to investigate the occurrence of Cryptococcus neoformans species in pigeon DROPping and Eucalyptus tree samples. Identification of the isolated Cryptococcus neoformans from pigeon DROPpings and Eucalyptus trees were done by both serology and polymerase chain reaction (PCR) techniques. A total of 100 samples were collected (50) dried and old pigeon DROPpings as well as (50) Eucalyptus tree samples. The pigeon samples were obtained collected while Eucalyptus tree samples were taken from 15 flowers, 15 leaves and 20 dust |
