Raillietia caprae (Acari: Raillietidae) and Psoroptes ovis (Acari: Psoroptidae) in the ears of goats in the state of Rio de Janeiro, Southeast Brazil.
Ear canals of 145 domestic goats including the breeds Saanen, Toggenburg, Anglobian, Alpine, Moxoto (native) and crossbred goats from 10 smallholder farms were examined by flushing for the presence of ear mites. Prevalence of Raillietia caprae Quintero, Bassols and Acevedo, 1980 was much more higher than Psoroptes ovis (Hering, 1838) in the studied area, respectively 62% (90/145) and 4% (6/145). The youngest animal parasitized was eight months old and the oldest was 10 years old. Subclinical otitis is a common feature of infestation by both species but increase of wax and the presence of pus were detected in the flushed material in approximately 10% of the goats examined.
