| Abstract | |
In 2017, an adult male South American sea lion (Otaria byronia), presenting emaciation and a cervical abscess, stranded alive in Florianopolis, southern Brazil. The animal was directed to a rehabilitation center, dying a few days later. On necropsy, the main gross findings were necrotizing lymphadenitis of the right prescapular lymph node and nodular bronchopneumonia. A novel alphaherpesvirus, tentatively named Otariid alphaherpesvirus 1, was amplified in several tissue samples. No histopathologic findings associated with viral infection were observed. Additionally, pulmonary tuberculosis by Mycobacterium pinnipedii was diagnosed by histopathological, immunohistochemical, and molecular techniques. Several bacteria were cultured from antemortem and postmortem samples, including Proteus mirabilis from the cervical abscess and cardiac blood, and Escherichia coli from the cervical abscess and pericardial effusion. Flavivirus, morbillivirus, and Apicomplexa were not detected by molecular techniques. Herein, we report a novel alphaherpesvirus in a pinniped species of the family Otariidae. Although previously described in Southern Hemisphere pinniped species, including South American sea lions, there is limited information regarding M. pinnipedii impact over this group. Further research is required to determine the associated pathogenesis of this novel herpesvirus, and prevalence of Otariid alphaherpesvirus 1 and M. pinnipedii in the reproductive colonies. (AU) | |
