Abstract

This study investigated the first outbreak of oriental theileriosis in a herd of beef cattle in South Australia using a newly established multiplexed tandem PCR (MT-PCR) to identify, differentiate and quantitate the four genotypes (buffeli, chitose, ikeda and type 5) of Theileria orientalis recognised to occur in Australasia. Following clinical diagnosis of oriental theileriosis (based on clinical signs, laboratory findings and post mortem examination), 155 blood samples were collected from individual cows (n = 85) and calves (n = 70), and tested by MT-PCR. In total, 117 (75.48%) cattle were shown to be test-positive for T. orientalis. All four genotypes were detected, and ikeda had the high..
