Figure 4From: 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 isotype-specific antibody titres in naturally PCV2-infected pigs. Full symbols: subclinically infected pigs, empty symbols: PMWS-affected pigs. Full line: mean antibody titre of healthy pigs, dashed line: mean antibody titre of PMWS-affected pigs. When the difference between the mean values was significant, the p-value was shown.Back to article page
