Abstract

Mycoplasma genitalium is a common sexually transmitted infection with a propensity to acquire resistance to commonly used antimicrobial therapies. Bacterial load has been linked to patient symptoms and the success of treatment. In this study we demonstrate methodology to estimate load from routine diagnostic assays using the ResistancePlus® MG test (SpeeDx Pty Ltd, Australia). The method gave comparable quantitation to an M. genitalium-specific 16S rRNA qPCR (Spearman r=0.94) for the samples analysed (n=499, including urine and swab types as detailed below), and was therefore employed to analyse typical load levels for samples in a diagnostic laboratory (total of 1012 tests). When stratified..
