title: Lack of hybridization between Yersinia enterocolitica and HLA-B27 DNA.
abstract: No homology was observed between Yersinia enterocolitica O:3 and HLA-B27 at DNA level when Yersinia enterocolitica chromosomal probes were hybridized with human HLA-B27 positive leukocyte DNA or in the hybridization of Yersinia DNA with HLA-B27 specific probe. Our results do not exclude the existence of molecular mimicry between Yersinia proteins and HLA-B27 antigen, since the crossreactive epitope might be a conformational determinant not detected with hybridization.
