Further evaluation of viral neutralization activity (%VN) against QIA244 using anti-PCV2 guinea pig sera derived from different genotypes of PCV2. QIA244 isolates were neutralized with anti-sera of Ingelvac CircoFLEX (a), QIA215 (b), QIA418 (c), and QIA169 (d) of up to 1:32 SN titer. As a control, homologous viruses were compared for each anti-serum. *Significantly different from control at p < 0.05
