Abstrakt: Q fever, caused by Coxiella burnetii, is an important zoonotic and public health concern worldwide. Kangaroos are thought to be a likely wildlife reservoir for C. burnetii in Australia and the kangaroo tick (Amblyomma triguttatum) has often been considered a vector. In this descriptive study of ticks collected from a population of eastern grey kangaroos (Macropus giganteus) with a high serological (84 %) and molecular (65 %) prevalence of C. burnetii in northern New South Wales, a total of 72 A. triguttatum ticks were tested by PCRs targeting the IS1111, htpAB, and com1 genes of the Coxiella genome. Despite the remarkably high prevalence of coxiellosis in the host population, none of the ticks were positive for Coxiella. This finding suggests that the kangaroo tick may not play a significant role in the transmission dynamics of C. burnetii in this particular host population.
