Abstract
A 2500-sow herd previously free of, and unvaccinated for, Mycoplasma hyopneumoniae became infected. Both M hyopneumoniae and influenza A H1N1pdm09 virus were identified in sows showing clinical signs. Coughing lasting 2 to 4 days was observed in approximately 10% of sows and 26 sows died over the course of the outbreak. There was no apparent impact on performance indicators. Polymerase chain reaction and serological results showed that M hyopneumoniae progression within the herd was fast and that infection may have occurred within a few weeks. An elimination program was quickly implemented so that sale of negative animals could resume.
