Primers and probes
Mycoplasma genitalium (MG) is a small pathogenic bacterium which infects epithelial cells of the urinary and genital tracts. MG is an emerging sexually transmitted infection occuring during unprotected sexual intercourse. MG is associated with notable reproductive tract syndromes such as cervicitis, pelvic inflammatory disease and infertility. MG has been strongly associated with urethritis in both men and women and with cervicitis in women. Among MG infected men, symptomatic urethritis is more common than asymptomatic urethritis. Culture is impossible to use in clinical practice due to the slow cell replication and fastidious growth requirements, reason why the Real-Time PCR has become the method of choice for the MG detection.
Treatment using Azithromycin is often recommended for treating MG infections but therapeutic failures have been reported in many cases of non-gonococcal urithritis caused by MG, because of the increased prevalence of resistance to macrolides. Resistance to macrolides of Mycoplasma genitalium is primarly caused by to mutations in the V region of the gene for 23S rRNA in nucleotides 2028 and/or 2059.
S-DiaMGResTM is designed to detect and identify macrolide resistance (mutation sites 2058 and 2059) after detection of Mycoplasma genitalium in the samples using the S-DiaMGTVTM kit.
