In an attempt to identify the vectors of Babesia canis, ticks were collected over a period of 3 years from a total of 395 dogs diagnosed as infected with this protozoan parasite at the Veterinary Faculty, Onderstepoort. Haemaphysalis leachi was the only tick species recovered from 164 of these dogs, and it occurred in mixed infestation on a further 140 of the dogs. Rhipicephalus sanguineus was collected in pure infestation from 59 dogs with a further 87 harbouring mixed infestations. Sixteen dogs harboured only Rhipicephalus simus and 58 others carried this tick in mixed infestations. Because the incubation period of B. canis is thought to be longer than the time most ixodid ticks spend on their hosts, no conclusion can be made on the vector status of any of the tick species. However, the majority of dogs diagnosed with clinical canine babesiosis at Onderstepoort were concurrently infested with H. leachi.
为了确定犬巴贝斯虫的传播媒介，在3年时间里，从 Onderstepoort 兽医学院共395只被诊断感染这种原生动物寄生虫的犬身上采集蜱虫。长角血蜱是从其中164只犬身上采集到的唯一蜱种，另外还有140只犬身上存在混合感染。血红扇头蜱从59只犬身上以单纯感染形式被采集到，另有87只犬存在混合感染。16只犬仅携带西门扇头蜱，另有58只犬存在混合感染。由于犬巴贝斯虫的潜伏期被认为比大多数硬蜱在其宿主身上停留的时间长，因此无法对任何蜱种的传播媒介地位得出结论。然而，在Onderstepoort被诊断患有临床犬巴贝斯虫病的大多数犬同时感染了长角血蜱。
