Resistance-guided treatment of infection at a UK sexual health centre.

We evaluated the ResistancePlus® MG assay in providing macrolide resistance-guided treatment (RGT) for infection at a UK sexual health centre. -positive samples from men with urethritis and women with pelvic inflammatory disease (PID) were tested for macrolide resistance-mediating mutations (MRMMs). MRMM-positive infections were given moxifloxacin 400 mg; otherwise 2 g azithromycin (1 g single dose and then 500 mg OD) was given.
