In this protocol, adjuvant arthritis (AA) is induced in Lewis rats in the classical manner using ground, heat-killed Mycobacterium tuberculosis H37Ra suspended in incomplete Freund's adjuvant (IFA; see Support Protocol). Disease development is monitored daily during the critical period (days 10 to 35 post immunization) using one or more possible techniques. The success rate of the procedure should approach 100%.
