Previous studies demonstrated the persistence of SVA RNA in the tonsil of experimentally or naturally infected animals long after resolution of the clinical disease. Here, we showed that SVA establishes persistent infection in SVA-infected animals, with the tonsil serving as one of the sites of virus persistence. Importantly, persistently infected carrier animals shedding SVA in oral and nasal secretions or feces can serve as sources of infection to other susceptible animals, as evidenced by successful transmission of SVA from persistently infected sows to contact piglets. These findings unveil an important aspect of SVA infection biology, suggesting that persistently infected pigs may function as reservoirs for SVA.<\/jats:p>","DOI":"10.1128\/jvi.00819-19","type":"journal-article","created":{"date-parts":[[2019,8,19]],"date-time":"2019-08-19T09:35:33Z","timestamp":1566207333000},"update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":51,"title":["Persistent Infection and Transmission of Senecavirus A from Carrier Sows to Contact Piglets"],"prefix":"10.1128","volume":"93","author":[{"given":"Mayara F.","family":"Maggioli","sequence":"first","affiliation":[{"name":"Department of Veterinary and Biomedical Sciences, Animal Disease Research and Diagnostic Laboratory, South Dakota State University, Brookings, South Dakota, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maureen H.
