Clinical laboratory assessments for Mycoplasma genitalium in a high-prevalence sexually-transmitted infection community reveal epidemiologic dichotomies with Trichomonas vaginalis

ABSTRACT

Introduction. Mycoplasma genitalium is an emerging agent of sexually-transmitted infection and is responsible for clinically-significant genital tract disease in both females and males. Similar to scenarios recently experienced with the urogenital flagellate Trichomonas vaginalis, an evolving molecular diagnostic reference standard based on transcription-mediated amplification allows for accurate detection of the organism, plus additional insight into disease epidemiology.

Areas covered. The basis for this article includes primary peer-reviewed literature plus compilations of data derived from routine clinical laboratory screening of females and males for agents of sexually-transmitted infection. Introductory laboratory and epidemiologic data related to T. vaginalis provides not only a foreshadowing to the dichotomies inherent to M. genitalium prevalence but also advocacy of a common non-invasive specimen source that could be used to screen females for both agents. This review also documents increased prevalence rates of M. genitalium in both females and males by way of transcription-mediated amplification.

Expert commentary. Molecular detection of M. genitalium should be a consideration in the development of comprehensive sexually-transmitted infection screening programs for both females and males. Transcription-mediated amplification has additionally identified novel facets of M. genitalium and T. vaginalis epidemiology that warrant further investigation.
