Key result
Genetic analysis of PCV2 from pigs in Chile revealed that 52% of sequences belonged to genotype PCV2b, 14% to PCV2a, and 34% were novel PCV2a/PCV2d recombinant viruses.

Novel PCV2 recombinants in Chile warrant local surveillance; leaves open effects on virulence and vaccine efficacy.
Observational (n=29)
Yes
The study identifies a novel cluster of Chilean PCV2 sequences resulting from intergenotypic recombination between PCV2a and PCV2d.
Neira et al. (2017) conducted an observational in Postweaning multisystemic wasting syndrome (PMWS) / Porcine circovirus type 2 (PCV2) (n=29). PCV2 infection was evaluated on PCV2 genotype distribution and recombination. Genetic analysis of PCV2 from pigs in Chile revealed that 52% of sequences belonged to genotype PCV2b, 14% to PCV2a, and 34% were novel PCV2a/PCV2d recombinant viruses.
