Otitis bovina por Rhabditis bovis en Córdoba, Colombia. Reporte de dos casos

Abstract

Two cases of pure Gyr bred bovines, treated at the outpatient medical-surgical clinic for large animals of the Faculty of Veterinary Medicine and Animal Husbandry, at the University of Cordoba, Colombia are reported. During the physical examination, the animals showed signs of clinical otitis with otorrhea, fetid odor, swelling with some degree of stenosis of the ear canal, head inclination, intense itching and excessive scratching of both ears. Direct inspection was performed and a collection of material from the outer ear canal was taken, the movement of parasites in the wax was directly observed, and later confirmed by observation under a stereoscopic microscope in the Parasitology laboratory of the Faculty of Veterinary Medicine at the University of Cordoba, which revealed the presence of nematode larvae and adults of the genus Rhabditis bovis. This is the first report of this disease in Gyr cattle in the department of Cordoba and in Colombia.
