Sero-negative polyarthritis. The Bedsonia (Chlamydia) group of agents and Reiter's disease. A progress report.

Abstract
Results of clinical examination of the genital tract and of laboratory tests are reported in 2 groups of patients: 20 patients probably suffering from Reiter''s disease, and 11 of their sexual contacts; 89 men presenting because of untreated "non-specific" urethritis, and 40 of their sexual contacts. Spurious isolation of members of the Bedsonia group has occurred in studies of laboratory technique. Results of investigations obtained so far are reconsidered in the light of these findings.
