It was found possible to correlate serological responses to porcine parvovirus (PPV) with the time after infection. Two procedures were used for PPV antibody measurement: an immunodiffusion technique to measure precipitating antibody and a haemagglutination inhibition (HI) procedure to measure concentration of 2-mercaptoethanol (2-ME) sensitive antibody. Both procedures successfully related antibody titres to time post-infection, but it was considered that a 2 M 2-ME HI procedure showed the greater promise for field investigations.
