Abstract

This study was carried out to detect Theileria infection in sheep and goats in Kurdistan region,
Iraq from June 2019 to April 2020. Molecular method was used to identify Theileria species. Sixty-
seven blood samples were taken from 45 sheep and 22 goats based on clinical signs of theileriosis
during tick activating season. The 67 samples were PCR edm and as a result, 20 species-specific PCR
were positives (26.67% (12/20) were Theileria ovis in sheep and 36.36% (8/20) were from goats). The
results of the gene analysis in the current study were registered in NCBI under four accession
numbers (MN889986, MN889987, MN889988 and MN889989), which shows that sheep and goats can
be infected with Theileria ovis. This is the first report of Theileria species in goats with clinical
theileriosis in Kurdistan, so the gene flow and disease transmission between sheep and goats is most
expected. PCR is a useful diagnostic tool to detect ovine theileriosis with a single test and suggested
that T. ovis is the dominant piroplasmid agent in Erbil. In addition, it revealed that sheep is very
susceptible to theileriosis than goats
