Archive Case #110: Swine Glassers Disease

Clinical Clues

1. A group of recently stressed young pigs becomes febrile and reluctant to move.
2. Several are depressed, sore, and breathing faster than expected.
3. Joints are swollen and painful in more than one pig.
4. Postmortem findings in a herd mate show fibrin on serosal surfaces, including the chest and heart.
5. The pattern is a polyserositis syndrome after weaning and mixing.
6. Glassers disease caused by Glaesserella parasuis produces fever, arthritis, pleuritis, and pericarditis in young pigs.

Diagnosis

Swine Glassers Disease

This case is most consistent with Swine Glassers Disease because the pigs have polyserositis, lameness, and systemic illness after weaning stress. The most important clues are the swollen joints and fibrinous serosal inflammation, which distinguish it from a simple enteric outbreak.
