Abstract
The quantity of streptococcal cell wall localized in the joints of rats of strains which are either susceptible (Sprague-Dawley, LEW/N, M520/N) or resistant (Buffalo, WKY/N, F344/N) to cell wall-induced chronic erosive arthritis was measured after intraperitoneal injection of group A streptococcal cell wall fragments. Susceptibility or resistance was not associated with a difference in the amount of cell wall localized in limbs or other tissues. It is concluded that although localization of cell wall in joint tissue is essential for development of arthritis, the relative resistance of certain rat strains reflects genetic regulation of inflammatory response rather than a quantitative difference in localization of cell wall in joints.
