Pneumonic pasteurellosis and enzootic pneumonia outbreak in a pig unit.

摘要

In June 2005, a 150-sow unit in Northern Ireland, UK, experienced an increase in respiratory problems and mortality in the dry sow house. This respiratory distress spread quickly into the service area, growing and finishing houses. An investigation was carried out involving clinical examinations, postmortem examinations, factory investigations and laboratory investigations. A diagnosis of pneumonic pasteurellosis and enzootic pneumonia was reached, based on bacterial isolation and positive Mycoplasma hyopneumoniae ELISA results in some animals. A control programme consisting of M. hyopneumoniae vaccination of piglets, feed inclusion of tilmicosin to the breeding pigs and tylosin to the growing/finishing pigs was introduced. Amoxicillin was included in the water tank of the breeding herd. This resulted in full recovery of the sows and control of the coughing in the growing/finishing pigs. Further lung scores are required in order to monitor the disease..
