Key result
Among 80 pigs in Thailand, the prevalence of porcine parvoviruses was 83% for PPV2, 73% for PPV3, 53% for PPV, 44% for PPV4, and 18% for PBo-likeV.
Cross-Sectional (n=80)
There is a high prevalence and co-infection rate of multiple porcine parvoviruses among pigs in the Chiangmai area of Thailand.
High prevalence in Thai pigs may warrant surveillance; hypothesis-generating for transmission dynamics and control.
Porcine parvovirus (PPV) causes reproductive failure in sows and has spread worldwide. Several new types of porcine parvoviruses have recently been identified in pig herds. The prevalence of five porcine parvoviruses in the Chiangmai area of Thailand was studied. The prevalence in 80 pigs was 53% for PPV (PPV-Kr or -NADL2 being the new abbreviations), 83% for PPV2 (CnP-PARV4), 73% for PPV3 (P-PARV4), 44% for PPV4 (PPV4), and 18% for PBo-likeV (PBoV7). Over 60% of the pigs carried more than three of the five porcine parvoviruses and occurrence together of the two pairs of viral genes, PPV1/PPV3 and PPV2/PBo-likeV were observed. Phylogenetic analyses for PPV2 and PPV3 indicated the existence of only two major clades of PPV2 and one major clade of PPV3.
