Mycoplasma genitalium macrolide and fluoroquinolone resistance detection and clinical implications in a selected cohort in New Zealand.

Coughlan E, Werno A, Anderson T
Mycoplasma genitalium has been associated with infections of the genitourinary tract and prevalence is secondary to Chlamydia trachomatis The clinical observation of increasing treatment failure indicating antibiotic resistance, especially in cases of recurrent urethritis, has been confirmed by molecular testing. Mutations in the 23S rRNA gene can cause macrolide resistance and topoisomerase/gyrase mutations can cause fluoroquinolone resistance. In this study, 115 M. genitalium DNA positive samples were analysed. Eighty nine (77.4%) samples had a 23S rRNA mutation present and 26 (22.6%) were wild type (no resistance mutation). Fluoroquinolone mutation screening was performed on 86 (74.8%) of the 115 samples which 20 (23.3%) samples had a mutation(s) associated with increased resistance. This study shows the increasing antibiotic resistance in New Zealand and the need for appropriate guidelines to treat at risk patients.
