Abstract
Sera from rabbits immunized with HLA-B27 lymphocytes showed increased activity against Klebsiella enterobacterial antigens using immunodiffusion, bacterial agglutination (P < 0.025), hemagglutination (P < 0.001) and radiobinding assays (P < 0.001). Immunoprecipitin lines were produced by these anti-lymphocyte sera against extracts from Yersinia enterocolitica and Shigella sonnci microorganisms. Rabbit anti-Klebsiella sera had lymphocytotoxic activity against HLA-B27 lymphocytes obtained from patients with ankylosing spondylitis (P < 0.001). Partial cross-reactivity may exist between some antigens found in several gram-negative microorganisms and HLA-B27 lymphocytes.
