Phylogeny-based rapid identification of mycoplasmas and ureaplasmas from urethritis patients.

ABSTRACT: Some strains of mycoplasmas and ureaplasmas (family Mycoplasmataceae) are associated with nongonococcal urethritis (NGU) or other genitourinary infections. We have developed a rapid and reliable method of identifying the presence and prevalence of mycoplasmas and ureaplasmas in men with NGU. This method is based on the amplification of a part of the 16S rRNA gene by PCR and phylogenetic analysis. A portion of the 16S rRNA gene from 15 prototype strains was amplified with a set of common primers, and their nucleotides were sequenced. The nucleotide sequence of the V4 and V5 regions was analyzed by the neighbor-joining method. The 15 prototype strains were grouped into three distinct clusters, allowing us to clearly segregate the strains into distinct lineages. To determine the prevalence of
