Abstract

Hemosporidians are intracellular protozoan parasites found in blood cells and tissues of their avian hosts. They are worldwide distributed and occur in a variety of avian species, including domestic chicken. Blood parasites among village chickens in Qaradagh district, Sulaimani Province in Kurdistan region Iraq, were surveyed during the period of March-June for the year 2012. Haemoparasites investigation was done by microscopic examination of stained blood films which prepared from 170 local chickens (Gallus domesticus).The overall prevalence of all species of haemosporidian parasites over the studied period in tested individuals was 133 (78.2%) with 114 (85.7%) single and 19 (14.3%) mixed genera infections. Plasmodiumspp. was the most prevalent haemoparasite (52.6%) followed by Haemoproteus spp., (19.5 %) and Leucocytozoon spp. (13.5%).The study has reported high prevalence rate of haemoparasites. There isn't enough information about prevalence of avian blood parasites in the studied area, the present study detect for the first time existent of haemoparasites.

Highlights

Introduction warmer months of the yearThe infective stageHaemosporidian parasites are common is the sporozoite which is present in the salivary blood parasites of reptiles, birds, and mammals glands of the insect vector (6)
Chickens (Gallus domesticus) are widely and tissues of their avian hosts, they are kept in studied area as the free-range village worldwide distributed and occur in a variety of chickens forming the largest proportion avian species, including domestic chicken, the compared to other farm birds, and previous avian haemosporidian parasites (Phylum- accounts of blood parasites in chicken in Apicomplexa) are taxonomically diverse and Sulaimani Province is relatively scarce, so the cosmopolitan in distribution infecting most bird study was aimed to determine the prevalence families (2)
The study was carried out in Qaradagh their degree of host specificity, and a broad host district, which located in about 45 Km, far range might even increase the general away from Sulaimani Province, Kurdistan transmission rate leading to a high prevalence region, Iraq

Summary

Introduction

Introduction warmer months of the yearThe infective stageHaemosporidian parasites are common is the sporozoite which is present in the salivary blood parasites of reptiles, birds, and mammals glands of the insect vector (6). Protozoan parasites found within the blood cells. Chickens (Gallus domesticus) are widely and tissues of their avian hosts, they are kept in studied area as the free-range village worldwide distributed and occur in a variety of chickens forming the largest proportion avian species, including domestic chicken, the compared to other farm birds, and previous avian haemosporidian parasites (Phylum- accounts of blood parasites in chicken in Apicomplexa) are taxonomically diverse and Sulaimani Province is relatively scarce, so the cosmopolitan in distribution infecting most bird study was aimed to determine the prevalence families (2). The most commonly recorded and type of hemoparasites infecting village parasites in smears of peripheral blood are chickens bordering the Qaradagh district in unicellular eukaryotic parasites of the genera, Sulaimani Province, Kurdistan
