title: Prevalence and Rate of Parasitemia of Haemoproteus columbae in Columba Iiviadomesticain Southwest of Iran.
abstract: BACKGROUND
  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.
  
  
  METHODS
  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.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  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.
