Detection of pathogens in aborted fetuses and stillborn piglets.
Proceedings of the 4th International Symposium on Emerging and Re-emerging Pig Diseases, 2003, 88-89
reproductive and respiratory virus (PRRSV), porcine parvovirus (PPV), leptospirae and chlamydiae/chlamydophilae are the pathogens commonly held responsible for reproductive disorders. However, the role played by PCV2 may be of interest. In this study, 202 aborted fetuses or stillborn piglets from 113 litters of 27 Austrian farms were investigated. The presence of PCV2 was unexpectedly demonstrated in 20.5% of the litters (61.1% of the investigated litters were tested positive for at least one infectious agent). In order to obtain a reliable etiological diagnosis in case of reproductive failures, it appears essential to examine numerous litters and take into consideration all pathogens mentioned above.
