ABSTRACT
Possible role of chlamydia trachomatis (C. trachomatis) in non-gonococcal Urethritis and chronic prostatitis was investigated by enzyme immunoassay technique in a study of 85 cases of non-gonococcal urethritis and 23 chronic prostatitis cases. 1. C. trachomatis was detected from 21 (24.7%) of 85 non-gonococcal urethritis patients and third decade represented the highest positive rate. 2. C. trachomatis was detected from 5 cases (21.7%) of 23 chronic prostatitis patients. 3. A significantly higher positive C. trachomatis detection rate of 60. 7% was obtained from those with a profuse urethral discharge compared with those with a scanty discharge. 4. A significantly higher positive C. trachomatis detection rate of 52.3% was obtained from cases with no previous history of urethritis compared with those who had previous history of urethritis in 85 cases of non-gonococcal urethritis.
