The focus on urogenital mycoplasmas as the possible etiologic agents of urogenital infections and syndromes, has increased in the last decade. Of these, Mycoplasma genitalium is proven to be pathogenic and sexually transmitted. We compared five commercially available assays for the detection of these organisms in urogenital mycoplasma culture specimen remnants. Stored specimen remnants were tested on Aptima Mycoplasma genitalium, Allplex™ STI Essential and CGMT, ResitancePlus®MG and Allplex™ MG & AziR Assays. All positive M. genitalium specimens and culture negative, nucleic acid positive Ureaplasmas were sent to the National Microbiology Laboratory for confirmation. The Aptima Mycoplasma genitalium assay detected 7 M. genitalium infections, the Allplex™ STI-EA and the Allplex™ CGMT detected 6 M. genitalium positives, and the Allplex™MG and AziR and SpeeDx ResistancePlus® MG detected 5 M. genitalium positives, four with macrolide resistant genes. The Allplex™ STI Essential assay was 100% sensitive and specific for Mycoplasma hominis and Ureaplasma targets. As seen in other studies, the Aptima Mycoplasma genitalium assay was 100% sensitive and specific for the detection of M. genitalium. The multiplex assays had lower sensitivities for M. genitalium detection (Allplex™ STI Essential and CGMT sensitivity of 85.71%; Allplex™ MG & AziR and SpeeDx ResistancePlus® MG sensitivity of 71.43%) with high specificities of 100%. Assays tested have high sensitivities and specificities for the detection of urogenital mycoplasmas especially M. genitalium macrolide resistance markers. All labs wanting to perform onsite detection of these organisms will find an assay to easily fit into their workflow. [ABSTRACT FROM AUTHOR]
