Antibodies to Klebsiella oxytoca and Proteus nurabilis in 21 active ankylosing spondylitis (AS). 13 active rheumatoid arthritis (RA), 19 inactive RA patients and 18 healthy controls were measured using enzyme-linked immunosorbent assay (ELISA)
Elevated anti-Klebsiella antibodies were demonstrated in active AS patients compared to active RA (p< (I (II). inactive RA patients (p< 0.001) and controls (p< 0 DOS) When measuring antibodies to Protein, active RA patients showed higher levels of antibodies compared to active AS patients (p< 0.005) and healthy controls (p< 0.05)
Further investigations are required to assess the role of Klebsiella and Proteus microorganisms in AS and RA respectively
