Farm Characteristics Affect PRRSV in UK Pig Herds
Charlotte M. Evans and colleagues at the Department of Biological Sciences at the University of Warwick in the UK have published a paper on their studies investigating the farm characteristics associated with the heterogeneity in seroprevalence in Porcine Reproductive and Respiratory Syndrome virus (PRRSV) in British pig herds. The observed variation in disease levels in infected herds appears to be related to the virus gradually fading out of the herd, and then being re-introduced rather than the persistence of the virus itself.
