Two cases of multidrug-resistant genitourinary Mycoplasma genitalium infection successfully eradicated with minocycline

Mycoplasma genitalium (MG) infection is a sexually transmitted infection that causes up to 25% of nongonococcal urethritis (NGU). MG strains carrying genetic markers of antimicrobial resistance that may affect treatment outcomes are increasingly recognized as a public health concern. We present two cases of persistent MG NGU with strains carrying both macrolide and quinolone resistance-associated mutations that were eradicated successfully by an extended course of minocycline.
