Key result
The prevalence of porcine parvovirus 2 in Japanese domestic pigs was 100% in sick pigs and 58% in healthy pigs, with multiple distinct strains coexisting across farms.
Why the study?
The prevalence and genetic diversity of porcine parvovirus 2 (PPV2) in Japanese domestic pigs were not well characterized.

The study demonstrates a high prevalence and genetic diversity of porcine parvovirus 2 in Japanese domestic pigs.
The porcine parvovirus 2 (PPV2) genome was first identified in 2001 in Myanmar. Recently, the PPV2 genome has been found in several other countries. In this study, the prevalence of PPV2 in Japanese domestic pigs was investigated and found to be 58% (69/120) in healthy domestic pigs and 100% (69/69) in sick domestic pigs. Sequencing and phylogenetic analysis of the PCR products of the VP1 gene and an almost full length PPV2 clone indicated that diverged PPV2 strains exist in Japan. Clearly distinct strains of PPV2 were detected in 7 of the 10 pig farms.

Saekhow et al. (2014) conducted a cross-sectional in Porcine parvovirus 2 (PPV2) infection (n=189). Porcine parvovirus 2 (PPV2) infection vs. Healthy pigs was evaluated on Prevalence of PPV2. The prevalence of porcine parvovirus 2 in Japanese domestic pigs was 100% in sick pigs and 58% in healthy pigs, with multiple distinct strains coexisting across farms.
