Some of the sexually transmitted diseases' agents other than human immunodeficiency virus (HIV) take an active part in transmission of HIV infection. The objective of the study was to determine the prevalence of Chlamydia trachomatis and Neisseria gonorrhoeae in 18 HIV positive men without urethritis symptoms and in 70 HIV negative men with urethritis symptoms as control group. The urine samples were screened for C.trachomatis and N.gonorrhoeae using polymerase, chain reaction (PCR). The prevalence of N.gonorrhoeae in HIV positive men without urethritis symptoms was significantly higher than that in HIV negative men with urethritis symptoms (p<0.05). HIV positive individuals should be considered as a high-risk group in respect to the other sexually transmitted diseases, thus necessitating screening for N.gonorrhoeae in order to break the infectious chain in these patients.
