Abstract

BACKGROUND:

Our previous study suggested a significant association between Ureaplasma urealyticum and nongonococcal urethritis (NGU). However, association of the serovars of U. urealyticum with NGU remains unclear. A polymerase chain reaction (PCR)-based assay can distinguish 4 serovars of Ureaplasma parvum from each other and categorize 10 serovars of U. urealyticum into 3 subtypes: subtype 1 (serovars 2, 5, 8, and 9), subtype 2 (serovars 4, 10, 12, and 13), and subtype 3 (serovars 7 and 11).

GOAL:

The goal of this study was to determine which subtypes of U. urealyticum are associated with NGU as determined by PCR-based assay.

STUDY:

The prevalence of U. urealyticum subtypes in 106 ureaplasma-positive men with urethritis was compared with that in 30 ureaplasma-positive men without urethritis.

RESULTS:

: In men with nonchlamydial NGU and men with Mycoplasma genitalium-negative nonchlamydial NGU, only U. urealyticum subtype 1 (serovars 2, 5, 8, and 9) was detected significantly more often than in men without urethritis.

CONCLUSION:

This study suggests that subtype 1 of U. urealyticum (serovars 2, 5, 8, and 9) is associated with NGU independently of Chlamydia trachomatis or M. genitalium.
