Chlamydia trachomatis (CT) is an obligate intracellular bacterium that causes genital disease and the most common sexually transmitted infection in the world. The most frequent risk factors associated with chlamydial infection are related to sexual behavior, multiple partners, and inconsistent condom use. Presenting primarily as urtheritis in men and cervicitis in women, CT a major cause of chronic pelvic inflammatory disease and subsequent infertility in women, eye and lung infection in

Polymerase chain reaction (PCR) is a sensitive and specific method for the detection of small quantity of bacterial DNA in clinical samples. The aim of this study was to determine the frequency of C. trachomatis by PCR in genital samples from patients in the city of Kerman. Methods: A total of 130 genital samples including 64 endocervical and 66 urethral swab samples were collected by physicians. Nucleic acid was extracted from each sample using a commercial DNA extraction kit. PCR primers specific for a conserved region of the C. trachomatis omp2 gene, encoding an outer membrane protein, were used for amplification. Results: A total of 9.2% (6.25% of cervicitis and 12.1% of urethritis) of the samples were found positive for CT using this PCR method. Conclusions: The present study shows a high prevalence of CT infection, especially in men with urethritis. Such patients should be referred to genitourinary clinics for treatment and partner notification. Given its worldwide prevalence, further CT studies on more populations are needed to assess potential public health implications of these infections.
