Parasitic infections in birds are omnipresent,
even when they occur in low amounts, may result in subclinical
diseases. There aren’t any studies, based on Iranian
data, investigating the prevalence of intestinal parasitic
infections in some birds’ species. We conducted a crosssectional
study between December 2011 and December
2012. The fecal samples were taken from 451 birds
including hen, turkey, sparrow, pigeon and decorative
birds. The samples screened for intestinal parasitic infections
using direct smear, formalin–ether concentration
technique, modified Ziehl–Neelsen staining, Culture in
RPMI 1640 medium, sporulation with potassium dichromate
and Trichrome and Giemsa staining. Out of 451 birds’
species, 157 (34.8 %), were infected with one or more type
of intestinal parasites. We identified two nematode, two
cestoda species and five protozoan parasites species. No
trematodes were found in the samples studied. The parasites
identified among birds involved Raillietina spp.
(4.2 %) and Eimeria spp. (7.1 %) were the most common
helminthes and protozoa respectively. From total of birds
study, 12 (2.7 %) and 6 (1.3 %) have two and three mixed
infections respectively. Intestinal parasitic infections are
common in birds in west Iran. The future studies are needed
in order to determine to which extent the infections
influence mortality and performance of the birds.
