Tick-borne haemoparasitic diseases (TBHDs), caused by Theileria, Babesia, Anaplasma and Ehrlichia, are common in regions of the world where distributions host, pathogen vector overlap. Many these threaten livestock production some also represent a concern to human public health. The primary aim this study was determine prevalence above-mentioned pathogens large number blood samples (n = 1979) collected from sheep 1727) goats 252) Turkey.

Theileria annulata is an obligate intracellular protozoan parasite of the phylum Apicomplexa. sporozoites invade bovine leukocytes and develop into a multinucleate syncytial macroschizont that causes uncontrolled proliferation dissemination infected transformed leukocytes. Activator protein 1 (AP-1) transcription factor driving expression genes involved in therefore key player Theileria-induced transformation. Ta9 possesses signal peptide allowing it to be secreted leukocyte cytosol...
