摘要：The presence of the specific antibodies for some enterobacteria - Yersinia, Salmonella and Shigella and Chlamydia , was investigated in patients with reactive arthritis and other rheumatoid diseases. The antibacterial antibodies in the diagnosis titers were found in 71 out of 489 patients: 54 of them were positive for enterobacteria and 17 for Chlamydia . From all positive patients 46 (64.7%) had clinical diagnosis of reactive arthritis, 20 (28.1%) of ankylosing spondilytis, each 2 (2.8%) of sacroilitis and Reiter’s syndrome and 1 (1.3%) with other disease. The most serology positive cases were of middle-age (31-50 years). There were no significant differences between sexes among serology positive cases.
