Ticks parasitising the Indian buffalo (Bubalus bubalis) and their possible role in disease transmission.

A total of 13 ixodid tick species, Boophilus microplus, Haemaphysalis bispinosa, Haemaphysalis cornupunctata, Haemaphysalis himalaya, Heamaphysalis montgomeryi, Hyalomma anatolicum anatolicum, Hyalomma dromedarii, Hyalomma marginatum isaaci, Hyalomma (Hyalommina) brevipunctata, Hyalomma (Hyalommina) hussaini, Nosomma monstrosum, Rhipicephalus haemaphysaloides, and R. turanicus were collected off 424 buffaloes from the northwestern states of India. Ten tick species, Amblyomma testudinarium, B. microplus, Haemaphysalis anomala, Haemaphysalis arborensis, Haemaphysalis bispinosa, Haemaphysalis intermedia, Haemaphysalis nepalensis, Haemaphysalis neumanni, R. haemaphysaloides, and R. turanicus parasitising 194 buffaloes were collected from the northeastern states of India. In addition to tick-buffalo relationships, the incidence of haemoparasites in buffalo from these two regions was studied and the possible role of these ticks in disease transmission was discussed. Examination of blood films and lymph smears revealed Anaplasma marginale and Babesia bigemina in 6.2 and 2.6%, respectively, of buffaloes tested in the northeastern states, and 14.9 and 4.7%, respectively, in the northwestern states.
