Popis: Plasmodium, Haemoproteus, and leukocytozoon are the most important hematozoa in birds, which have been reported in different areas of the world. The present study was undertaken to find which blood protozoans exist in indigenous chickens in Shiraz, southern Iran and to evaluate hematological parameters in birds infected with hematozoas. Plasmodium and Aegyptianella were the two parasites found in 740 blood samples examined from indigenous chickens of which 29 (3.91%) were positive for Aegyptianella pullorum, 106 (14.32%) for Plasmodium gallinaceum, and 12 (1.62%) for A. pullorum and Plasmodium gallinaceum together. There was no significant difference between hematological parameters of non-infected and naturally infected chickens with Plasmodium gallinaceum, A. pullorum, and both (P > 0.05). Low infection of indigenous chickens with A. pullorum, Plasmodium gallinaceum, and both had no significant effects on hematological parameters (P > 0.05), which is probably due to low parasitemia rate and immunity against these two parasites.
