Abstract

Streptococcal cell wall (SCW) arthritis in rats is an experimentally-induced inflammatory model with many features that resemble rheumatoid arthritis (RA) in humans. In this unit, Lewis rats are injected with an aqueous suspension of Group A SCW streptococcal cell wall peptidoglycan-polysaccharide polymers (SCW PG-PS) and observed for the development of arthritis. The resulting arthritis is biphasic. An acute phase typically develops within 48 hr, followed 10 to 21 days later by a chronic phase which persists for months. Support protocols are included for preparing Group A PG-PS and measuring PG-PS concentration.
