The purpose of this study was to investigate seroprevalence of porcine respiratory diseases including porcine reproductive and respiratory syndrome (PRRS), porcine circovirus-2 (PCV-2), Mycoplasma hyopneumonia (MH), Pasteurella multocisa A (PMA), Haemophilus parasuis (HP), Actinobacillus pleuropneumonia type 2 (APP2), and Actinobacillus pleuropneumonia type 5 (APP5) in Jeonbuk state by enzyme-linked immunosorbent assay (ELISA). Total 5488 samples collected from four breeding pig farms and 55 commercial pig farms were tested. The overall seroprevalence of PCV-2, APP2, APP5, PMA, and HP was higher in breeding pig farms than in commercial pig farms, with higher antibody positivity rate (more than 97%) in breeding pig farms. Seroprevalence of MH or PRRS were 68.4% and 48.7% or 79.4% and 58.2% in commercial pig farms or breeding pig farms, respectively. The overall seroprevalence of the porcine respiratory diseases tested in this study varied depending on the age group of pigs, with the 40-day-old pig group showing the lowest seroprevalence and mean S/P titer ratio.

Abstract
The purpose of this study was to investigate seroprevalence of porcine respiratory diseases including porcine reproductive and respiratory syndrome (PRRS), porcine circovirus-2 (PCV-2), Mycoplasma hyopneumonia (MH), Pasteurella multocisa A (PMA), Haemophilus parasuis (HP), Actinobacillus pleuropneumonia type 2 (APP2), and Actinobacillus pleuropneumonia type 5 (APP5) in Jeonbuk state by enzyme-linked immunosorbent assay (ELISA). Total 5488 samples collected from four breeding pig farms and 55 commercial pig farms were tested. The overall seroprevalence of PCV-2, APP2, APP5, PMA, and HP was higher in breeding pig farms than in commercial pig farms, with higher antibody positivity rate (more than 97%) in breeding pig farms. Seroprevalence of MH or PRRS were 68.4% and 48.7% or 79.4% and 58.2% in commercial pig farms or breeding pig farms, respectively. The overall seroprevalence of the porcine respiratory diseases tested in this study varied depending on the age group of pigs, with the 40-day-old pig group showing the lowest seroprevalence and mean S/P titer ratio.
