Parasites affect the health and productivity of birds. Haemoproteus columbae occurs in pigeons widely in tropical and subtropical regions. The present investigation was concentrated on the prevalence of H. columbae and rate of parasitemia in domestic pigeons in southwest of Iran.
Pigeons regimented in three groups, less than six months old, between six and twenty four months old and more than twenty four months old.Then stained blood smears were studied for presence of H. columbae and finally rate of parasitemia in every group calculated.
Mature and immature stages of H. columbae gametocytes were found in 24% of blood smears prepared from 100 healthy domestic pigeons. Mean of parasitemia in infected pigeons was 9.58%. Mean size of macrogametocytes was 4μm×15μm and mean size of microgametocytes was 3μm×12μm. Mean of parasitemia in infected females was more than males and pipers. Mean of parasitemia in infected old pigeons (pigeons with more than twenty four months old) was more than pigeons with less than six months old and pigeons between six and twenty four months old.
This study show the prevalence and rate of parasitemia in domestic pigeons in southwest of Iran. We should be care about this parasite in pigeons by knowing the prevalence and high risk groups.
寄生虫会影响鸟类的健康和生产力。鸽血变原虫广泛存在于热带和亚热带地区的鸽子中。本研究集中于伊朗西南部家鸽中鸽血变原虫的流行情况及寄生虫血症发生率。
将鸽子分为三组，年龄小于6个月、6至24个月以及大于24个月。然后对染色血涂片进行研究以检测鸽血变原虫的存在情况，最后计算每组的寄生虫血症发生率。
在从100只健康家鸽制备的血涂片中，24%发现了鸽血变原虫配子体的成熟和未成熟阶段。感染鸽子的寄生虫血症平均率为9.58%。大配子体的平均大小为4μm×15μm，小配子体的平均大小为3μm×12μm。感染雌性鸽子的寄生虫血症平均率高于雄性和幼鸽。感染的老鸽（年龄大于24个月的鸽子）的寄生虫血症平均率高于年龄小于6个月的鸽子以及年龄在6至24个月之间的鸽子。
本研究显示了伊朗西南部家鸽中寄生虫血症的流行情况和发生率。通过了解流行情况和高危群体，我们应该关注鸽子中的这种寄生虫。
