Project: Additional serological and virological research on epidemiology of PCV2 in farms with or without PCVD, before and after vaccination with circovac

15/12/10 – 31/12/11

The aim of the study was first to establish PCV2 virus load in faeces and Ab profiles of pigs from PCVD affected (AH) and nonaffected herds (NAH). In a second step, the effect of sows vaccination (Circovac) on the virus load and Ab profiles is investigated. A higher virus shedding was found in AH. The effect of vaccination is still under investigation.
