Acute Anaplasma ovis infections can cause severe clinical symptoms and might lead to significant economic losses in small ruminant flocks.

However, little information has been provided related the prevalence of anaplasmosis in Angora goats.

The study was designed to investigate the prevalence of Anaplasma ovis serologically (cELISA) and microscopically (Giemsa stained blood smears) among Angora goats from Duhok districts of the northern part of Iraq.

A total of 92 blood samples were randomly collected from three localities of Duhok city; Zakho, Batel and Sumil during the study period from April to October 2009.

The infection rate of A.

ovis was 38.04% by Giemsa stained blood smear and 66.3% by cELISA.

The prevalence of A.

ovis in female goats was higher than that in males, but statistically not significant difference (P>0.05) by using both methods.

The prevalence was also significantly higher (P<0.05) in goats more than three years old than in younger ones.

The highest prevalence of A.

ovis was found in Zakho, whereas the lowest was reported in Sumail.

Results of hematological parameters indicated microcytic hypochromic type of anemia.It is concluded that A.

ovis can infected Angora goats in district Duhok, Kurdistan region, Iraq and this might be due to high distribution of the disease and its transmitters which were lead to substantial effect followed by high mortalities
