摘要

Otobius megnini (spinose ear tick) is a cosmopolitan soft tick that parasitizes domestic and wild mammals, as well as humans. The larval and nymphal stages are common parasites that feed on blood inside the canal ears of hosts, while adults are nonfeeding and live off the host. Different nymphal stages of O. megnini were collected from a jaguar (Panthera onca) suffering from otitis in captive conditions from Guerrero, Mexico. This is the first documentation worldwide of O. megnini in a jaguar with otitis. The presence of this tick species represents a risk of transmission to animals and humans exposed to the nymphal stages of the tick.
