An indirect-fluorescent antibody procedure was used to assay swine serum for the presence of porcine circovirus (PCV) antibodies. We tested sera from 11 Georgia swine herds, one herd from North Carolina and one herd from lowa.Antibodies against PCV were found in an average of 53% of the samples tested. The incidence varied from a low of 27% to a high of 100%. The antibody titers on one of the farms varied from 1:8 to 1:256.A titer of 1:8 or greater is considered to be positive. The significance of PCV infections has not been determined and further studies are needed to determine the possible role this virus might have in disease.
