Figure 1From: Correlation between the presence of neutralizing antibodies against porcine circovirus 2 (PCV2) and protection against replication of the virus and development of PCV2-associated diseaseCourse of IPMA and SN (sensitive) antibody titres in experimentally PCV2-inoculated gnotobiotic and SPF pigs. Full symbols: pigs with low PCV2 replication (gnotobiotic) or subclinically infected pigs (SPF); empty symbol: pig with high PCV2-replication (gnotobiotic) or PMWS-affected pigs (SPF).Back to article page
