Novel alphaherpesvirus in a wild South American sea lion (Otaria byronia) with pulmonary tuberculosis.

ABSTRACT: In 2017, an adult male South American sea lion (Otaria byronia), presenting emaciation and a cervical abscess, stranded alive in Florianópolis, 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 mira
