A non-syndromic approach to treatment of people with non-gonococcal urethritis (NGU) requires identification of pathogens and understanding of the role of those pathogens in causing disease. The most commonly detected and isolated micro-organisms in the male urethral tract are bacteria belonging to the family of Mycoplasmataceae, in particular Ureaplasma urealyticum and Ureaplasma parvum. To better understand the role of these Ureaplasma species in NGU, we have performed a prospective analysis of male patients voluntarily attending a drop in STI clinic in Oslo. Of 362 male patients who were tested for NGU using microscopy of urethral smears, we found the following sexually transmissible micro-organisms: 16% Chlamydia trachomatis, 5% Mycoplasma genitalium, 14% U. urealyticum, 14% U. parvum and 5% Mycoplasma hominis. We found a high concordance in detecting in turn U. urealyticum and U. parvum using 16s rRNA gene and ureD gene as targets for nucleic acid amplification testing (NAAT). Whilst there was a strong association between microscopic signs of NGU and C. trachomatis infection, association of M. genitalium and U. urealyticum infections in turn were found only in patients with severe NGU (>30 polymorphonuclear leucocytes, PMNL/high powered fields, HPF). U. parvum was found to colonise a high percentage of patients with no or mild signs of NGU (0-9 PMNL/HPF). We conclude that urethral inflammatory response to ureaplasmas is less severe than to C. trachomatis and M. genitalium in most patients and that testing and treatment of ureaplasma-positive patients should only be considered when other STIs have been ruled out.

No aetiology is found in up to 40% of men with symptomatic urethritis. Male partners of women with bacterial vaginosis (BV) may be at higher risk of non-gonococcal urethritis (NGU). The aim of this study was to examine the role of BV associated bacteria in first-void urine (FVU) in 97 asymptomatic men without urethritis (controls) and 44 men (cases) with NGU including 20 men with idiopathic urethritis (IU) attending a Swedish STD-clinic between January and October 2010. BV-associated bacteria and ureaplasmas were detected by quantitative PCR assays. All BV associated bacteria, except Megasphaera-like type 1, were strongly positively correlated with U. urealyticum p<0.005 and even stronger with the combined U. urealyticum and U. parvum load (p<0.0005) suggesting that ureaplasma induced elevated pH may stimulate the growth of BV associated bacteria. No statistically significant differences were found between IU cases and controls in the prevalence or load of BV associated bacteria or ureaplasmas. In multiple logistic regression, Megasphaera-like type 1 was associated with IU (p = 0.03), but most positive FVU samples contained very few bacteria and the finding may not be clinically relevant.
