Figure 2From: First construction of infectious clone for newly emerging mutation porcine circovirus type 2 (PCV2) followed by comparison with PCV2a and PCV2b genotypes in biological characteristics in vitroIdentification of four cloned strains of different PCV2 genotypes (PCV2a/rCL, PCV2b/rJF, PCV2b/rYJ and PCV2d/rBDH) including two new emerging mutants by IPMA. Each of the four rescued strains reacted with swine anti-PCV2 positive sera. PCV2/LG strain was included as a positive control and PK15 cells were used as negative control.Back to article page
