Molecular epidemiology of senecavirus A associated with vesicular disease in pigs in Brazil.


Senecavirus A (SV-A) may cause vesicular disease and neonatal mortality in pigs, and was first detected in Brazil in 2015. Samples including tissues and serum from pigs with suspected vesicular diseases were collected from January to August in 2015 from farms in the states of Minas Gerais, Santa Catarina, Goiás and Rio Grande do Sul, Brazil, and tested for the presence of SV-A by reverse transcriptase PCR. All samples were negative for foot and mouth disease virus, as well as 13 other infectious agents associated with vesicular diseases in pigs. SV-A was detected by PCR in 65/265 (24.5%) specimens. A 530 base pair fragment sequenced from the VP1 protein coding region indicated a high genetic distance from SV-A in other countries, but a common origin among the Brazilian isolates.
