Background  Apicomplexan tick-borne pathogens that cause disease in companion animals include species of  Babesia  Starcovici, 1893,  Cytauxzoon  Neitz & Thomas, 1948,  Hepatozoon  Miller, 1908 and  Theileria  Bettencourt, Franca & Borges, 1907. The only apicomplexan tick-borne disease of companion animals that is known to occur in Australia is babesiosis, caused by  Babesia canis vogeli  Reichenow, 1937 and  Babesia gibsoni  Patton, 1910 .  However, no molecular investigations have widely investigated members of Apicomplexa Levine, 1980 in Australian ticks that parasitise dogs, cats or horses, until this present investigation.    Results  Ticks ( n  = 711) removed from dogs ( n  = 498), cats ( n  = 139) and horses ( n  = 74) throughout Australia were screened for piroplasms and  Hepatozoon  spp. using conventional PCR and Sanger sequencing. The tick-borne pathogen  B. vogeli  was identified in two  Rhipicephalus sanguineus  Latreille ticks from dogs residing in the Northern Territory and Queensland (QLD).  Theileria orientalis  Yakimov & Sudachenkov, 1931 genotype Ikeda was detected in three  Haemaphysalis longicornis  Neumann ticks from dogs in New South Wales. Unexpectedly, the exotic tick-borne pathogen  Hepatozoon canis  James, 1905 was identified in an  Ixodes holocyclus  Neumann tick from a dog in QLD. Eight novel piroplasm and  Hepatozoon  species were identified and described in native ticks and named as follows:  Babesia lohae  n. sp.,  Babesia mackerrasorum  n. sp.,  Hepatozoon banethi  n. sp.,  Hepatozoon ewingi  n. sp.,  Theileria apogeana  n. sp.,  Theileria palmeri  n. sp.,  Theileria paparinii  n. sp. and  Theileria worthingtonorum  n. sp. Additionally, a novel cf. Sarcocystidae sp. sequence was obtained from  Ixodes tasmani  Neumann but could not be confidently identified at the genus level.    Conclusions  Novel species of parasites in ticks represent an unknown threat to the health of companion animals that are bitten by these native tick species. The vector potential of Australian ticks for the newly discovered apicomplexans needs to be assessed, and further clinical and molecular investigations of these parasites, particularly in blood samples from dogs, cats and horses, is required to determine their potential for pathogenicity.
