Mycoplasma genitalium bacterial loads (log10) and treatment outcomes, Melbourne Sexual Health Centre, Melbourne, Victoria, Australia, 2012–2016. A) M. genitalium load compared in urine (n = 67), rectal swab (n = 26), and cervical swab (n = 3) samples. For urine vs. rectal samples, p = 0.56; for urine vs. cervical samples, p = 0.70. B) Comparison of pretreatment M. genitalium loads in infections not cured (n = 26) and cured (n = 71) by pristinamycin. p<0.01. C) Comparison of M. genitalium loads in pretreatment and posttreatment samples from cases in which pristinamycin failed (n = 26). p<0.001..Box plots indicate 25th percentile (bottom of box), 75th percentile (top of box), median (horizontal line within box), and range (whiskers).
