- To investigate the blocking effects of classical swine fever (CSF) spleen vaccine on vertical transmission of classical swine fever virus (CSFV) and porcine reproductive and respiratory syndrome virus (PRRSV) co-infection in sows. Sows infected CSFV+PRRSV were selected from three large-scale pig farms and they were randomly divided into group I and group II. The sows in the group I were set as experimental group and vaccinated with CSF spleen vaccine at a 2 times normal dose per pig; and sows in group II were set as control group and vaccinated with CSF cell vaccine at a 6 times normal dose per pig. The antigens of piglets were detected by enzyme-linked immunosorbent assay (ELISA) method. Our results revealed that the blocking rate on the antigen of piglets in the experimental group (79.25%, 42/53) was significantly higher than that in the control group (50.94%, 27/53) (p<0.01). Collectively, these results demonstrate that CSF spleen vaccine has a good blocking effects on vertical transmission of CSFV+PPRSV co-infection in sows.
