ALARCON, Gonzalo et al. Usefulness of conventional polymerase chain reaction for the detection of Mycoplasma hominis, Ureaplasma spp. and Trichomonas vaginalis in female outpatient's genital samples. Rev. chil. infectol. [online]. 2016, vol.33, n.1, pp.26-29. ISSN 0716-1018.

Introduction: Trichomonas vaginalis, Mycoplasma hominis and Ureaplasma spp. are microorganisms responsible for genitourinary and pregnancy pathologies. Nucleic acid amplification methods have shown several advantages, but have not been widely studied for the detection of these microorganisms. Aim: To implement a conventional polymerase chain reaction (PCR) for the detection of the microorganisms and to compare its results versus the methods currently used at our laboratory. Material and Methods: 91 available samples were processed by PCR, culture (M. hominis y Ureaplasma spp.) and wet mount (T vaginalis). Results were compared and statistically analyzed by kappa agreement test. Results: 85, 80 and 87 samples resulted in agreement for the detection of M. hominis, Ureaplasma spp. y T. vaginalis, respectively. For M. hominis and Ureaplasma spp., agreement was substantial, whereas for T. vaginalis it was moderate, however, for the latter, PCR detected more cases than wet mount. Conclusion: We recommend the implementation of PCR for detection of T. vaginalis whereas culture kit is still a useful method for the other microorganisms.

Keywords : Mycoplasma hominis; Ureaplasma spp; Trichomonas vaginalis; polymerase chain reaction; DNA; culture.
