The aim of this study was to determine the
prevalence of Haemoproteus columbae and Trichomonas
gallinae in pigeons (Columba domestica) in Isfahan, Iran.
Study was done on 100 pigeons from January to June 2010
in Isfahan located in south of Iran. Oropharyngeal swabs
were taken from all birds. Also blood samples were
obtained from wing vein and thin smears were prepared
from them. All smears were stained by Giemsa and were
examined by immersion. Out of 100 Oropharyngeal swab
smears 57 (57%) were positive for T. gallinae and Haemoproteus
gallinae were detected in 62 pigeons (62%)
from which blood smear were taken. The present study is in
close agreement with other studies in Iran. But infestation
rate to theses parasite in world are very different. These
differences were probably linked to geographical variations
and differences in the feeding habitat and abundance of
vehicles of Haemoproteus.
