Failure to detectMycoplasma fermentans, Mycoplasma penetrans, orMycoplasma pirum in the urethra of patients with acute nongonococcal urethritis

Abstract
Urethral swab specimens collected from 108 male Japanese patients with acute nongonococcal urethritis (NGU) and from 50 Japanese men without NGU were examined for the presence ofMycoplasma fermentans, Mycoplasma penetrans, andMycoplasma pirum by means of polymerase chain reaction-based assays. These mycoplasmas were not detected in any of the specimens, which suggests that they are unlikely to have a pathogenic role in acute NGU.
