Epidemiological studies on tropical theileriosis (Theileria annulata infection of cattle) in Kurdistan Region, Iraq

Abstract

In an ad hoc survey conducted during 2006, the epidemiology of tropical theileriosis in Kurdistan Region, Iraq, was addressed. For this purpose, a total of 299 blood samples were collected from female cattle older than 1 year reared under open system management in Duhok (n=99), Sulaimanyia (n=100) and Erbil (n=100) governorates. The samples were subjected to TaSP indirect ELISA as well as polymerase chain reaction (PCR) and nested PCR assays. The results indicated that the seroprevalence was 77.9%, and PCR reported an infection rate of 68.9% in the Kurdistan Region of Iraq. The implication of the results in the epidemiology of tropical theileriosis in the region is discussed with emphasis on comparisons between the two tests used and recommendations for the future work are outlined. © Springer-Verlag 2009.
