The bacteria localises in joints causing destruction of the synovial membrane lining, hyperaemia, villus formation and lymphocyte and plasma cell infiltration resulting in chronic serofibrinous polyarthritis.

Initially joints are hot and swollen leading to stiffness, lameness, non-weight bearing on affected limbs and eventual ankylosis. Discospondylitis can also occur if animals are chronically affected.

Additionally valvular lesions may develop in the heart causing chronic valvular [[Endocarditis| endocarditis]], vegetative thrombosis of mitral valves and asymptomatic or congestive heart failure sometimes resulting in sudden death following stress.
