摘要：

Changes in porcine circovirus type 2 (PCV-2) genotypes were evaluated before, during and after outbreaks of post-weaning multisystemic wasting syndrome (PMWS) in (1) a retrospective study using pig sera collected in Spain from 1985 to 2008 and (2) a longitudinal study using pig sera collected from two farms in Spain over periods of 7 and 14 years. In both studies, there was a rapid genotypic shift from PCV-2a to PCV-2b that was related to the peak of PMWS epizootics in Spain and the appearance of PMWS on the two farms studied longitudinally.
