Abstract

Bovine theileriosis is an arthropod-borne disease caused by one or more haemoprotozoan parasites of the genus Theileria. Traditionally, Theileria infection in cattle in Australia was largely asymptomatic and recognized to be associated with Theileria buffeli, now assigned to the Theileria orientalis-group. There have been some recent outbreaks of theileriosis in dairy and beef cattle, mainly in subtropical climatic zone (New South Wales) of Australia. Here, we provide the first published evidence of an outbreak of bovine theileriosis in the south-eastern Australia (state of Victoria) linked to the ikeda and chitose genotypes of T. orientalis. Future investigations should focus sharply on the elucidating the epidemiology and ecology of Theileria in this region to subvert the possible impact on the cattle industry.
