PCR assays are nowadays between the most sensitive and reliable methods for screening and diagnosing sexually transmitted infections (STIs). The aim of this study was to analyze the reliability, accuracy, and usefulness of the new NG OligoGen kit in comparison with the cobas 4800 assay for the detection of Neisseria gonorrhoeae in clinical samples. A prospective study was designed for detection of N. gonorrhoeae including urine samples (n=152), rectal (n=80), endocervical (n=67), pharyngeal (n=41), and urethral swabs (n=5) that were sent from a regional STI clinic in Seville, Spain. Samples were collected from 255 (73.9%) men and 90 women. Sensitivity, specificity, positive and negative predicative values, and kappa value for N. gonorrhoeae detection using the NG OligoGen kit were 99.6%, 100%, 100%, 99.1%, and 0.99, respectively. Statistical data obtained in this study confirm the usefulness and reliable results of this new assay.

PCR methods are nowadays between the most rapid and sensitive methods for screening and diagnosing herpes simplex virus (HSV) type 1 and 2. The aim of this study was to analyze the reliability, accuracy, and usefulness of the new assay HSV OligoGen kit in comparison with the Roche LightCycler HSV ½ Qual Kit assay for the detection of HSV in clinical samples. For this analysis, a prospective study was designed for detection of HSV-1 and HSV-2 including 110 ulcer specimens, 48 urine, 48 endocervical, 43 cerebral spinal fluids, 4 urethral and 3 pharyngeal swabs that were sent from a regional STI clinic or an Intensive Clinical Unit, both in Seville, Spain.

Introduction: A prospective study was designed to assess the performance of the new CT OligoGen kit and the cobas 4800 assay for detection of Chlamydia trachomatis.
Methods: A set of samples that included urine samples (n=212), endocervical (n=167), rectal (n=53), pharyngeal (n=7) and urethral swabs (n=3). The samples were sent from a regional sexually transmitted diseases (STD) clinic in Seville, Spain, and were collected from 261 men and 181 women.
