 genus and piroplasmids of the genus [6], Abstract—Haemoproteus is a genus of protozoa that occurs some of which are pathogenic to humans [4]-[7]. In columbids greatly in avian populations, usually found in the peripheral blood of seven species of Haemoproteus were described: H. columbae, hosts from anywhere in the world. It is usually non-pathogenic and in H. sacharovi, H. maccallumi, H. melopeliae, H. turtur, H. pigeons only causes disease when they are stressed. The aim of this study was to determine the prevalence of in perise and H. palumbis [8]. Iranian pigeons by a molecular technique (PCR). A study was done H. columbae is transmitted by Hypoboscidae flies and on 220 pigeons from September 2012 to April 2013 in the southwest culicoides mosquitoes. H. columbae is widely dispersed in the of Iran. Blood samples were obtained from wing vein. This present world, especially in warm and temperate climates. The study showed that the prevalence rate of Haemoproteus columbae gamonts of H. columbae develop from tiny forms to elongated, was 23.18% (51/120). Considering the lack information about the crescent-shaped forms, which partially surround the nucleus of prevalence of pigeon blood parasites in the southwestern of Iran, more precise molecular surveys seem to be necessary regarding the the host red blood cells. presence of Haemoproteus columbae parasite in Iranian pigeons. The occurrence of H. columbae has been studied all over the world. There is very limited number of studies on pigeon Keywords— cyt B gene, H. colusmbae, Iran, PCR. blood parasites in Iran [5]-[9]. Thus, the aim of this study was to determine the frequency of H. columbae in Iranian pigeons I. INTRODUCTION using PCR.

Blood Samples Collection morphologically distinct parasites have been described and classified in two subgenera, Haemoproteus and The study was carried out from September 2012 to April Parahaemoproteus [1]. Haemoproteus is a genus of protozoa 2013, involving 220 free living pigeons from five localities that is parasitic on birds, reptiles and amphibians. These including shahrekord, farsan, kiyar, borujen and lordegan in protozoans parasitize many birds overall the world and in Chaharmahal Va Bakhtiari province, Iran. Age and weight of some bird flocks, between 50–100% of the individuals are all pigeons were recorded. Their body weights ranged from infected with these haemospororin blood parasites [2]-[3]. 130 to 230g and their ages were between 6 months to 3 years. Feral and domestic pigeons are correlated with human All the birds were kept in isomanagerial and nutritional habitation, often occupying and befouling buildings where regimen, allowing the water and feed at a temperature of 28ºC. people work and live [4]. Pigeons are distributed everywhere Blood samples were obtained from wing vein and thin blood on earth and domesticated for hundreds of years. Pigeons have smears were prepared from them. Blood samples were stored been used for a long time as a meat resource, laboratory in EDTA and kept in refrigerator. animals, pets or cultural and religious symbols. In Iran, B.
