FERNANDEZ-MOLINA, Carmen et al. Diagnosis of Mycoplasma genitalium by MgPa and rRNA 16S gene amplification. Salud pública Méx [online]. 2008, vol.50, n.5, pp.358-361. ISSN 0036-3634.

OBJECTIVE: Mycoplasma genitalium has been associated with nongonococcal urethritis (NGU). Diagnosis by PCR has become the primary detection method for this organism. Thus, diagnosis by DNA amplification using the PCR technique should be utilized. MATERIAL AND METHODS: GMF/GMR and MgpF/MgpR primer pairs, complementary to the M. genitalium 16S rRNA and MgPa genes, respectively, were selected. Specificity and sensibility assays were conducted and clinical samples were studied. RESULTS: The PCR with each primer pair was specific only for M. genitalium, and the sensibility was higher with the GMF/GMR primers. In the study of 34 clinical samples, 18,5% were positive for M. genitalium, with more positive samples when the MgpF/MgpR primers were used. CONCLUSIONS: DNA amplification by PCR should be applied in clinical practice to the diagnosis of M. genitalium in patients with NGU should using.
