Seroprevalence of porcine circovirus type 2 infection in the area of Vojvodina

The aim of this research was to determine seroprevalence of infection caused by PCV2 in different categories of pigs on the territory of Vojvodina. The research was conducted on 6 pig farms placed in different locations on the territory of Vojvodina (two farms from the territory of Backa, Banat and Srem, respectively), with the capacity from 500 to 2,500 sows with intensive management, closed type. Blood samples from brachioce?phalic plexus were collected from 540 pigs in three different categories, in suckling piglets between 3 and 4 weeks of age, in weaned piglets from 8 to 9 weeks of age, and in fattening pigs between 20 and 22 weeks of age. Specific anti-PCV2 antibodies are determined by using indirect ELISA. Based on our results, we conclude that PCV2 infections are widely spread on the territory of Vojvodina, with total seroprevalence of 74.8%. The highest value of seroprevalence is determined in category of fattening pigs 86%, in suckling piglets this was 74.5%, while in weaned piglets seroprevalence was 65.3%.
