In this study, 105 PRDC-affected pigs were investigated for the presence of PCV2 and other viral and bacterial pathogens. Most of these pigs were infected by more than one pathogen. PCV2 was detected in 81% of the cases which represents the highest prevalence among viral pathogens (PRRSV 62.9%, parvovirus 57.1% and SIV 13.3%). In 55% of the cases, PCV2 and PRRSV were detected concurrently. Furthermore, PCV2 resulted associated with Pasteurella multocida and Mycoplasma hyopneumoniae in 44.7% and 38.8% of the cases respectively. Even if the exact role of PCV2 is not understood yet, it is likely to be greatly involved in PRDC.
