Occurrence of ticks (Acari: Ixodidae) in the municipality of Goiatins, Tocantins

Due to a suspected human case of Brazilian Lyme-like disease in the city of Goiatins, Tocantins State, an epidemiological survey was carried out in eight counties in this region during September 2007 and February 2008, where 1,890 ticks were collected from domestic animals and from the environment. A total of eight tick species were identified: Rhipicephalus sanguineus, Rhipicephalus (Boophilus) microplus, Dermacentor nitens, Amblyomma cajennense, Amblyomma oblongoguttatum, Amblyomma ovale, Amblyomma parvum and Amblyomma tigrinum. The last four species were described for the first time in this region. Although human parasitism by ticks is frequently described in Goiatins, no ticks collected from humans were analyzed. The Study of ixodids in this region contributes with the survey of Brazilian ticks, as well as the elucidation of the possible transmission of the agent that caused the Brazilian Lyme-like disease case in Goiatins
