PDF version is available online.

This case study describes sudden deaths of pigs in a North Carolina production system at three different finishing facilities between June 2019 and February 2020. The cases involved 3- to 6-month-old pigs of the same genetics but from different sow farm flows. Pigs at all three sites had gross lesions that included firm, deep red to purple lungs. Based on laboratory results from tissue samples, all cases were diagnosed with Actinobacillus suis. Treatments and the significance of this disease in swine are discussed.
