Serpens Species Bacterin



Serpens Species Bacterin is intended for vaccination of otherwise healthy cattle against Papillomatous digital dermatitis (PDD, hairy footwart, strawberry heel wart). Serpens Species Bacterin prevents PDD in lesion-free animals, and aids in the treatment of lesions due to PDD in currently affected animals. Serpens Species Bacterin contains killed cultures of an isolate of Serpens Species bacteria. The original isolate was obtained from PDD lesions.

Papillomatous Digital Dermatitis (pdd): Disease Description
Papillomatous digital dermatitis is a chronic disease of the feet and lower legs of cattle. This disease is clinically manifested by skin lesions which may be ulcerative or proliferative in nature. The lesions are typically located near the skin/horn junctions of the digit and may result in severe lameness with secondary production and reproductive losses.
