What is the etiology of Pigeon Breast?

Pigeon breast (pigeon fever) is caused by Corynebacterium pseudotuberculosis. This bacterium often leads to caseous abscesses in the pectoral muscles and along the ventral abdomen in horses, producing the characteristic chest swelling described as pigeon breast. The other organisms listed can cause abscesses or respiratory infections in different contexts, but they do not produce the classic pectoral muscle abscesses that define pigeon fever.
