Abstract

This study aimed to evaluate the natural infection by SaV in pigs of different categories of production cycle in an important Brazilian pig-producing region. Faecal samples (n = 169) of suckling, post-weaning, finisher and breeder pig categories were analysed. Animals were from five farrow-to-weaning and nine grower-to-finish commercial pig farms. The RT-PCR assay was performed targeting the partial RNA-dependent RNA polymerase (RdRp) gene of porcine SaV genome. The virus was detected in 23.7 % (40/169) of faecal samples and in 10/14 (5/5 farrow-to-weaning; 5/9 grower-to-finish) of pig farms evaluated. Porcine SaV was most frequently (p < 0.05) detected in pigs at post-weaning than in grower-to-finish and breeder categories. The phylogenetic analysis revealed that the porcine SaV strains belong to the GIII and GIX? genogroups. This study showed that the porcine SaV GIII genogroup has spread in the pig herds and provides the first evidence of GIX? genogroup circulation in South America.
