First record of Otobius megnini (Dugés, 1883) (Ixodida: Argasidae) found on Bos primigenius taurus in San Juan province, Argentina

Abstract

Otobius megnini is a species of tick frequently found on cattle, sheep, goats, South American camelids, dogs, and humans. It is widely distributed in Argentina, however, it was not mentioned in the province of San Juan, Argentina. This species is of veterinary importance because the infection causes otitis, which is notorious when the parasitic load is high. Due to this, the objective of this note is to mention the first nymphal record of the soft tick Otobius megnini for the San Juan province, Argentina, collected at the bottom of the auditory pavilion of a specimen of Bos primigenius taurus. This note provides new information on parasitism in domestic exotic cattle, expanding its distribution to the province of San Juan, Argentina.
