Induction of Experimental Chronic Arthritis in Rabbits by Cell-free Fragments of Erysipelothrix

RESUMO
A cell-free crude extract of Erysipelothrix rhusiopathiae injected by high pressure jet into the knee-joint of rabbits stimulated an acute, mild inflammatory reaction. Additional injections at 3-day intervals induced a chronic condition characterized by hyperplasia of the synovial cells and hypertrophy of the villi, due to infiltration by lymphocytes and plasma cells which formed aggregates resembling Allison-Ghormley bodies. There was also extensive proliferation of stroma vasculature and fibrous tissue. A similar jet injection of the diluent produced an early, transient, acute, and mild inflammation. A mechanism is postulated for fixation of one or more of the chemically characterized antigens in or near the synovium as a means of inducing the localized inflammatory response that predisposes the joint to infection.
