Overview

Piroplasmosis is an important tick-borne disease in several regions, and can lead to significant economic animal production losses. The current study aimed to systematically examine the incidence of bovine piroplasmosis in Kashgar, Xinjiang, to provide baseline data for the effective prevention and control of this disease among bovines in the region. A total of 1403 bovine blood samples from 12 sampling points were screened via PCR with universal Piroplasma primers targeting the 18S rRNA locus and specific Theileria annulata primers targeting the cytochrome b ( COB ) gene. The overall prevalence of bovine Piroplasma was 65.9% (925/1403). Three species of pathogenic Theileria , including T. annulata , T. orientalis , and T. sinensis , were detected, and the infection rates for these species were 65.1% (913/1403), 0.5% (7/1403), and 0.1% (1/1403), respectively. The mixed infection rate for T. orientalis and T. annulata was 0.3% (4/1403). No Babesia was detected in this study. In conclusion, bovine piroplasmosis was still common in Kashgar and T. annulata was the dominant species, and a mixed infection of T. annulata and T. orientalis was detected. Notably, T. sinensis was reported for the first time in this region. Therefore, strategies for the prevention and control of bovine piroplasmosis should be enhanced.
