Abstract excerpt
This study investigated the presence and genetic diversity of porcine circovirus type 3 (PCV3) in Vietnam. Fifteen samples from sows with reproductive disorders across five provinces were screened by qPCR; those with Ct-values < 25 underwent sequencing. Whole-genome analysis revealed multiple polymorphisms, including a notable A24L substitution in the ORF2 Cap protein. Phylogenetic results showed 13 strains...
