M. agalactiae bovis causes polyarthritis in feedlot cattle, M. mycoides var. capri causes polyarthritis and serositis in goats and M. capricolum causes polyarthritis in goats and sheep.
periosteal proliferative polyarthritis
occurs in young, adult male cats as an acute, febrile illness accompanied by severe joint pain and stiffness, followed by generalized stiffness, swollen joints and akylosis.
