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
