Abstract
Increased lymphocyte transformation (LT) responses have been observed in Yersinia infections against the causative bacterium and against other enterobacteria. The responses of patients with reactive arthritis are lower than those of non-arthritic patients. The LT responses against several gram-negative bacteria and against a pair of enterobacterial common antigen (ECA)-positive and ECA-negative Salmonella typhimurium strains in patients after Yersinia or Salmonella infection were studied. The haptenic ECA alone seemed not to be responsible for the increased LT responses. Thus some other common antigenic determinants present on the bacteria are responsible for the LT response.
