The role of mycoplasmas in non-gonococcal urethritis: a review.
نویسنده
چکیده
The criteria that need to be fulfilled before regarding a mycoplasma as a cause of non-gonococcal urethritis (NGU) are outlined. Of the seven mycoplasmas that have been isolated from the human genitourinary tract, most cannot be considered as contenders for causing NGU. Although there is no evidence to support an etiological role for Mycoplasma hominis, it may be unwise to ignore this mycoplasma in view of its known pathogenicity in other situations. The cumulative weight of evidence indicates that strains of Ureaplasma urealyticum (ureaplasmas) cause NGU in some patients. The reason for their occurrence in the urethra of some men without disease needs to be established. Ureaplasmas do not seem to cause post-gonococcal urethritis. The role in NGU of M. genitalium, newly discovered in the male urethra, is unknown, but its biological features, morphological appearance, and ability to cause genital disease in marmosets suggest that it may be pathogenic for man.

on agar medium and have subsequently been referred to as T-strain mycoplasmas or T-mycoplasmas. Shepard (1956) noted that T-strain mycoplasmas were present in a high proportion of patients with non-gonococcal urethritis, and it was suggested that the organisms played a part in the aetiology of that disease. Because of the increasing prevalence of non-gonococcal urethritis, this hypothesis has s...
متن کاملPrevalence of Urogenital Mycoplasmas Among Men with NGU in Upper Silesia, Poland. Preliminary Study.
The prevalence of urogenital mycoplasmas in men with NGU in Upper Silesia (Poland) was studied. Mycoplasmas were detected in 36.7% men (Ureaplasma parvum and Mycoplasma genitalium were found in 30% and 16.7% respectively). Urealyticum urealyticum was not detected. We suggest including M. genitalium in the diagnostic scheme for nongonococcal urethritis (NGU).

The term "T-strain" was applied by Shepard (1954) to a strain of mycoplasma which, when cultured on solid agar, shows morphological differences from other members of the species (Shepard, 1956). Shepard (1954) recovered T-strain mycoplasmas from urethral scrapings taken from cases of nongonococcal urethritis (NGU) and later found that this organism was present in some 70 per cent. of such cases...
