Review of Australian species of Theileria, with special reference to Theileria buffeli of cattle

Abstract

This review describes 4 species of parasites in Australia generally regarded as Theileria. The physiological and epidemiological characteristics of the species that occurs in cattle are discussed. Confusion still surrounds the relationship of this species with benign species of Theileria in other countries. Arguments are presented to support the proposal that the bovine species in Australia is correctly designated Theileria buffeli and that this name should apply to all the benign species of Theileria of cattle in Eurasia. The other 3 species considered in the review are proposed species from marsupials. Of these, only Theileria tachyglossi can confidently be included in the genus Theileria, because schizonts have yet to be detected in the other 2 species.
