Ticks on buffaloes (Bubalus bubalis) in the state of Rio de Janeiro, Brazil.

Some tick species have been described parasitizing buffaloes, but reports from Brazil are rare. This study aimed to ascertain the species of ticks that parasitize buffaloes in the state of Rio de Janeiro. Seventeen farm properties were visited between June 2008 and December 2009, and buffaloes were inspected in relation to infestation. The ticks were identified and a semi-structured questionnaire on parasitism and treatment against ticks was filled out through interviews with the owners. The species identified were Rhipicephalus (Boophilus) microplus, Dermacentornitens and Amblyommacajennense. It was noted that 82.3% (14/17) of the properties visited presented animals infested with ticks, although 76.5% (13/17) had been administering acaricide treatment. Buffaloes in the state of Rio de Janeiro are often parasitized by ticks, especially in the larval and nymph stages.
