“…In addition, PCV2 was found to be associated with porcine dermatitis and nephropathy syndrome (PDNS) (Wellenberg et al, 2004), respiratory disease complex (Kim and Chae, 2003) and reproduction failure (Sanchez et al, 2001). Several qualitative PCR methods have been described for the detection of PCV2 in fresh and fixed material (Allan et al, 1999;Hamel et al, 2000;Kim and Chae, 2003;Larochelle et al, 1999;Ouardani et al, 1999).
