The transovarial transmission of Babesia trautmanni by Rhipicephalus simus to domestic pigs.
Rhipicephalus simus was, for the first time, experimentally proven to be a transovarial vector of Babesia trautmanni of domestic pigs. The nymphal and adult progeny of experimentally infected female ticks transmitted the infection to 2 susceptible splenectomized pigs. Features of the infection included a prepatent period of 6-8 days post-tick infestation, a febrile reaction for 3 days and a maximum parasitaemia score of 15 (more than 6 parasites per 300 red blood cells). Other clinical signs in both pigs were mild inappetence and listlessness. Both pigs recovered without any antibabesial therapy.
