Abstract
The Brazilian tick fauna currently comprises 77 valid species categorized into two families: Ixodidae (53 species) and Argasidae (24 species). In the state of Alagoas, only six Ixodid ticks have been reported to date, with no previous reports of ticks in the Argasidae family. Here, we assessed 33 White-eared Opossum (Didelphis albiventris Lund, 1840) rescued in the metropolitan region of Maceió and referred to the Wild Animal Screening Center (Cetas) in the city. Upon arrival, the animals were examined for ectoparasites within 24 hours. In total, 10/33 (30%) opossums were found to be infested by 26 larvae of the argasid tick Ornithodoros mimon Kohls, Clifford & Jones, 1969. Morphological identification of ticks was corroborated by generating partial sequences of the mitochondrial 16S rRNA gene from three tick specimens. This study marks the first report of an argasid tick in the state of Alagoas. Future studies should investigate whether populations of both O. mimon ticks and their host, D. albiventris, in the state of Alagoas carry potential zoonotic agents capable of causing tick-borne diseases.
