“…Overall, the most prevalent genotypes detected in this study were F (25.6z), E (17.1z), and J (16.3z). This C. trachomatis genovar distribution pattern is similar to the patterns that have been reported among male patients in Guangdong province (6,7) and Taiwan (12), female sex workers in southern China (13), prostitutes and non-prostitutes in Thailand (14) as well as female patients in Japan (15). These genovars may be the most prevalent circulating in Asia (14,15), and possibly the world (16).…”

“…Lastly, 50% of chlamydia-positive specimens were able to be sequenced, lower than in previous studies. 16,60 The main reason may be due to low chlamydial load in the original urine specimen from an asymptomatic infection, and degradation of the targeted ompA DNA over the one-year 2808C freezer storage.…”

“…6 -14 Limited genotyping data in Taiwan indicated that serovar E was the most common serovar, followed by serovar F in sexually transmitted disease (STD) clinic patients. 15,16 Therefore, we designed this study to determine: (i) the prevalence of both non-sexual risk-taking behaviours and sexual behaviours in Taiwanese teenagers using the AORT-CASI approach; (ii) the prevalence of C. trachomatis and N. gonorrhoeae infections by NAATs; (iii) the distribution of C. trachomatis serovars; and (iv) the association between sexual risk behaviours and infection.…”

The objective of this study was to determine the prevalence of high-risk sexual behaviours and sexually transmitted infections (STIs) and associated risk factors in Taiwanese high school students. Students in grades 10 and 11 (mean age: 15.9 +/- 0.9; range: 13-20 years) at two schools were recruited. An anonymous online real-time computer-assisted self-interviewing questionnaire was designed to assess demographic factors and sexual behaviours. Urine specimens were tested for genital chlamydial and gonococcal infections. The same survey and screening was conducted one year later on the same group of students. Overall, 670 individual students (993 visits) were enrolled with 323 students in both surveys. Twenty-seven percent had had sexual intercourse, and more than three quarters (79%) of them had engaged in high-risk sexual behaviours. Having friends using drugs increased the odds of practicing high-risk sexual behaviours (odds ratio [OR] 1.99, 95% CI: 1.13 to 3.50). Among 182 sexually active students, 8.8% had chlamydial (female: 12.5%; male: 5.3%) and 1.1% had gonococcal infections. Having sex with someone met on the Internet was the most significant risk factor for acquiring chlamydia (OR 8.14, 95% CI: 2.82 to 23.51). In conclusion, this adolescent population reported high prevalence of high-risk sexual behaviours and had a high prevalence of chlamydia supportive of a potential epidemic of STIs and HIV.

An improved nucleic acid amplification test (NAAT) to detect Chlamydia trachomatis infections, based on PCR amplification within its cryptic plasmid (CT1/CT2 Test) was developed. DNA was extracted from urogenital swabs and a 594-bp long DNA fragment from the cryptic plasmid (pCT) was amplified. The sensitivity and specificity of the CT1/CT2 Test were determined to be 100 and 99%, respectively, when directly compared with current amplification kit for sexually transmitted diseases (MPCR). Basic epidemiological data related to the patients attending gynecological and/or urological clinics are also provided. The overall prevalence rate in this group of patients suspected for C. trachomatis infection was determined to be about 95 per 1000 (88 and 107 per 1000 in females and males, respectively). It demonstrates that the CT1/CT2 Test is suitable for epidemiological screening and/or diagnostic practice.

Abstract: C. trachomatis genital infection was prevalent among male patients attending a STD clinic in Taipei. Young Taiwanese men attending STD clinics should be counselled on condom use.
