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.
墨西哥钝缘蜱（刺耳蜱）是一种广泛分布的软蜱，寄生于家养和野生哺乳动物以及人类。幼虫和若虫阶段是常见的寄生虫，以宿主耳道内的血液为食，而成虫不进食，靠宿主之外的环境生存。从墨西哥格雷罗州一只圈养条件下患中耳炎的美洲豹（美洲豹）身上采集到了不同若虫阶段的墨西哥钝缘蜱。这是全球首次记录到患中耳炎的美洲豹身上有墨西哥钝缘蜱。这种蜱虫的存在对接触其若虫阶段的动物和人类构成了传播风险。
