Table 1. Information of CPV-2 strains in this study
The result revealed the co-circulation of New CPV-2a and CPV-2c strains in China. No CPV-2, CPV-2a, CPV-2b, New CPV-2b variants were detected. CPV-2c was the predominant variant detected in 19 samples (70.3%), while New CPV-2a variants were only detected in 6 samples (22%). Noteworthily, two FPLV were identified in dog samples and successfully isolated. It was reported that FPLV strains can replicate only in feline cells(Nakamura et al., 2001). However, this study provided two exceptions.
