Abstract: Osteopathologies and tooth alterations in Otaria byronia (Pinnipedia, Otariidae) from Rio Grande do Sul coast, Brazil. Bone diseases and tooth alterations in 47 specimens of Otaria byronia (Blainville, 1820), from southern Brazilian coast, were analized. Tooth wear and the associated bone pathologies were determined, as well as their percentuals. The main infection was osteomyelitis associated with tooth alterations, such as fractures and attrition, both of them exposing the pulp chamber. Tooth attrition incre… Show more

“…According to Niven et al (2004), a variety of diseases such as anthrax (Dragon et al 1999) and tuberculosis (Rothschild et al 2001) can affect living populations of large ungulates and may cause defective enamel formation. The occurrence of tuberculosis is not uncommon in wild animals and has previously been recorded in a Pleistocene bison, identified by erosive lesions in the skeleton (Rothschild et al 2001;Rothschild & Laub 2006), and in a specimen of Otaria byronia (Blainville 1820), exhibiting osteopathology suggestive of tuberculosis in the skull, as well as EH (Braunn & Ferigolo 2004). Parasites also affect bison (Niven et al 2004) and other large ungulates, and their presence has been related to the formation of EH in cattle (Suckling et al 1983).…”

“…O canino superior direito mostra fratura de esmalte na face distal, e o canino inferior esquerdo apresenta fratura horizontal da coroa (Figuras 1A a 1F). Desgastes dentários e fraturas são registrados por Braunn e Ferigolo (10) em Otaria flavescens ( = O. byronia; Pinnipedia) e por Aguiar et al (11) em Didelphis albiventris (Didelphimorpha). Alterações rostrais severas que podem conduzir a alterações dentárias foram registradas em Pontoporia blainvillei (Pontoporiidae) por Gerholdt (12), todavia a autora não analisa efeitos da má-oclusão.…”
