Development of PCR assays for detection of Trichomonas vaginalis in urine specimens.

چکیده
Trichomonas vaginalis infections are usually asymptomatic or can result in nonspecific clinical symptoms, which makes laboratory-based detection of this protozoan parasite essential for diagnosis and treatment. We report the development of a battery of highly sensitive and specific PCR assays for detection of T. vaginalis in urine, a noninvasive specimen, and development of a protocol for differentiating among Trichomonas species that commonly infect humans.

Improved detection by DNA amplification of Trichomonas vaginalis in males.
Trichomoniasis is a sexually transmitted infection that is highly prevalent worldwide and has been linked to preterm birth and human immunodeficiency virus acquisition. In females, trichomoniasis causes vaginitis, while in males, it is frequently asymptomatic but can be a cause of urethritis. Control efforts have been hampered by the lack of a sensitive diagnostic technique for this infection i...
متن کاملDetection of trichomonosis in vaginal and urine specimens from women by culture and PCR.
Vaginal trichomonosis is a highly prevalent infection which has been associated with human immunodeficiency virus acquisition and preterm birth. Culture is the current "gold standard" for diagnosis. As urine-based testing using DNA amplification techniques becomes more widely used for other sexually transmitted diseases (STDs) such as gonorrhea and chlamydia, a similar technique for trichomonos...
متن کاملComparison between the Gen-Probe transcription-mediated amplification Trichomonas vaginalis research assay and real-time PCR for Trichomonas vaginalis detection using a Roche LightCycler instrument with female self-obtained vaginal swab samples and male urine samples.
This study compared two assays for Trichomonas vaginalis detection, Gen-Probe's transcription-mediated amplification (TMA) assay for Trichomonas vaginalis and BTUB FRET PCR, using self-obtained clinical samples from 611 patients. Infection status was defined as two positive results by two different tests. The initial TMA assay sensitivity was 96.7%; specificity was 97.5%. The TMA assay was comp...
متن کاملUse of the Roche LightCycler instrument in a real-time PCR for Trichomonas vaginalis in urine samples from females and males.
Trichomonas vaginalis is the agent of a highly prevalent sexually transmitted infection (STI) that can result in vaginitis, urethritis, and preterm birth. Traditional methods of diagnosis, including wet preparation, can be unreliable. In this study, we describe the adaptation of an existing PCR method for specific detection of T. vaginalis DNA into a rapid real-time PCR assay based on fluoresce...
متن کاملComparison of culture and different PCR assays for detection of Trichomonas vaginalis in self collected vaginal swab specimens.
OBJECTIVES DNA amplification techniques have become widely used for the diagnosis of sexually transmitted infections. For the detection of Trichomonas vaginalis, PCR techniques are not yet widely used despite the publication of several assays. The sensitivity and specificity of five independent primer sets were determined on self collected vaginal specimens obtained from female commercial sex w...
