CALDERON, Alfonso; CARDONA, José  y  VARGAS, Marlene. PREVALENCE OF Rhabditis sp. PARASITIC OTITIS IN CATTLE FARMS GYR IN CORDOBA, COLOMBIA. rev.udcaactual.divulg.cient. [online]. 2016, vol.19, n.1, pp.149-154. ISSN 0123-4226.

Within the genus Bos indicus, the Indubrasil and Gyr breeds are more susceptible to Rhabditis bovis parasitic otitis. The Gyr breed due to its characteristics, in the colombian Caribe has been selected for milk production. The objective was to determine the prevalence of Rhabditis sp., parasitic otitis in Gyr cattle farms in different livestock enterprises in Cordoba, Colombia. A prospective descriptive study was implemented by convenience. Swabs of cerumen from ear canals of 136 cattle were collected in six cattle farms. The diagnostic criterion was the direct observation of the mass movement of cerumen and visualization of nematodes. The prevalence of parasitic otitis was 83.82%. Significant difference was found for the variables clinical otitis, otorrhea and odor, the sex variable was not analyzed. Parasite diagnosis shows the existence of Rhabditis sp. as the cause of parasitic otitis in cattle in livestock farms in Cordoba (Colombia).
