Key result
PCV2a and PCV2b genotypes have been circulating in Colombian swine since at least 2002, with PCV2b becoming the predominant genotype in both healthy and PCVAD-affected pigs over time.
Observational (n=306)
Yes
The study demonstrates the historical presence and molecular evolution of PCV2 genotypes in Colombian swine populations.

PCV2b circulated in Colombia before 2007 outbreaks; extends molecular epidemiology but leaves open introduction routes and vaccine strain selection.
Monroy et al. (2014) conducted an observational in Porcine circovirus-associated disease (PCVAD) (n=306). Porcine circovirus type 2 (PCV2) infection was evaluated on Detection and molecular characterization of PCV2 DNA. PCV2a and PCV2b genotypes have been circulating in Colombian swine since at least 2002, with PCV2b becoming the predominant genotype in both healthy and PCVAD-affected pigs over time.
