title: [Pathogenesis of ankylosing spondylitis: relation between HLA-B 27 and Klebsiella aerogenes].
abstract: The Authors attested the evidence of a cross-reactivity among some Klebsiella antigens and HLA B 27 positive lymphocytes, suggesting the hypothesis that Klebsiella may be an initiating agent in ankylosing spondylitis (AS). The Authors determined also serum antibody response against Klebsiella antigens in AS patients. The results obtained are discussed.
