Associations among Haemophilus parasuis Mycoplasma hyorhinis and porcine reproductive and respiratory syndrome virus infections in pigs with polyserositis

摘要

The objective of this study was to determine the associations among Haemophilus parasuis, Mycoplasma hyorhinis, and porcine reproductive and respiratory syndrome (PRRS) virus (EU-field strain) infections in 95 pigs with polyserositis. A significant association between H. parasuis and M. hyorhinis was identified. H. parasuis and M. hyorhinis were significantly more often detected in PRRS virus positive pigs.
