US - Previously in this column, we have discussed the symptoms and virulence of porcine circovirus associated disease (PCVAD), writes JoAnn Alumbaugh on

We have also explained that PCVAD can have a more significant impact on a herd if other diseases, like porcine reproductive and respiratory syndrome (PRRS) are present.

Dr. John Waddell at the Sutton Veterinary Clinic in Sutton, Nebraska, has found that vaccinating pigs for those diseases currently found in the herd might lower the impact of PCVAD. Dr. Waddell uses a preventative program by vaccinating pigs for PRRS, ileitis, Salmonella choleraesuis and Mycoplasma.

"We have not experienced any severe circovirus-related cases, so we’re wondering, and this is speculation, if doing a good job controlling cofactors like PRRS, mycoplasma and salmonella helps to prevent the devastating effects of circovirus associated disease," says Dr. Waddell.
