Blood parasites of cattle in Papua New Guinea: a review.
A history is given of the occurrence of bovine blood parasites, namely Theileria spp., Babesia bovis, B. bigemina, Trypanosoma theileri, Eperythrozoon sp. and Anaplasma marginale, found in Papua New Guinea. Reference is made to the vectors, the epidemiology and the disease outbreaks associated with some of the parasites. The likelihood of new blood parasites entering the country is considered to be small but the presence of cattle tick (Boophilus microplus) and rusa deer (Cervus timorensis) in a few localities place at risk the maintenance of the present restricted distribution of the more important parasites and constitute a potential quarantine hazard.
