Completing the cycle: Haemaphysalis elliptica, the vector of Babesia rossi, is the most prevalent tick infesting black-backed jackals (Canis mesomelas), an indigenous reservoir host of B. rossi in South Africa.

Abstrakt: In sub-Saharan Africa, virulent babesiosis in domestic dogs is primarily caused by Babesia rossi. Black-backed jackals (Canis mesomelas), indigenous hosts of B. rossi, are the most likely reservoir from which B. rossi became established in domestic dog populations in South Africa. Haemaphysalis elliptica is the only confirmed vector transmitting B. rossi to domestic dogs; very little was known about the prevalence of H. elliptica infestation in black-backed jackal populations. All jackals (n = 9) from a site in Gauteng Province, South Africa, were infested with H. elliptica, which was also the most numerous tick recovered. Rhipicephalus simus was the second-most prevalent tick. Low numbers of four other tick species were recovered. An extended dataset (n = 23) including published data on adult black-backed jackals (n = 14) from other parts of South Africa indicated that H. elliptica (74%) was the most prevalent species, followed by R. simus (44%). Published data from black-backed jackals (n = 12) in Kenya showed a prevalence of H. leachi sensu lato infestation of 93%. We conclude that where its off-host ecological requirements are met, H. elliptica/leachi is the most prevalent tick infesting black-backed jackal population throughout their range. A comprehensive checklist, with discussion, is given for the 29 tick species reported from black-backed jackals in both southern and northeastern Africa.
