Tenosynovitis in broiler breeder flocks causes severe lameness and malnutrition, with histological changes suggesting a probable viral etiology.
Hypothesis-generating for viral tenosynovitis in broilers; prospective virological studies needed before changing management.
Tenosynovitis in commercial broiler breeder flocks, characterised by severe lameness, resulted in malnutrition and eventual culling of these chickens. Histologically there was metaplasia of tendons, tendon sheaths, connective tissues and infiltration with heterophils. Although Staph. aureus was isolated from some specimens, it is probable that the condition is of viral origin: the virus has not yet been isolated.
