Not just where the ticks are: Insights into Theileria orientalis Ikeda in Australia 1: University of New England, Australia; 2: EMAI, Department of Regional NSW, Australia Theileria orientalis Ikeda has been a significant cause of disease in the Australian cattle industry for over a decade. To investigate how widespread T. orientalis Ikeda is across Australia, particularly in regions in and outside of known ranges of the vectors and in the absence of clinical disease, we conducted testing on herds of homebred adult cattle in New South Wales and Queensland. Molecular testing of 526 blood samples from 49 properties was performed to detect and quantify different T. orientalis genotypes present within these herds. Previous studies have shown that in clinical cases of theileriosis, the Ikeda genotype is detected in 88% of samples. Preliminary findings suggest that T. orientalis Ikeda may be more widespread than previously thought, including in areas outside the known ranges of the tick vectors. These detections in herds that have not experienced clinical disease indicate that presence of the organism may be a necessary but not sufficient cause of disease on its own. These results help build a clearer understanding of clinical theileriosis in Australia and highlight the value of ongoing active surveillance. Future work to include additional Australian states is planned. | |
