PURPOSE: Because of the inconsistent symptoms associated with Ureaplasma infections, their clinical significances in genitourinary tracts are under debate. Therefore, we evaluated the presence of Ureaplasma urealyticum (UU) and Ureaplasma parvum (UP) in urine samples and examined their associations with chronic prostatitis (CP) through a case and control study. MATERIALS AND METHODS: We included 696 nonchlamydial nongonococcal (NCNG) urine samples from men; 350 were categorized into non-inflammatory CP, 88 in inflammatory CP, and 258 in non-CP group. We amplified a region in the Ureaplasma urease areas from these samples and determined their biovars using the Sanger method. RESULTS: Among the NCNG population, the rates of UU, UP, and non-UU/UP were 3.88%, 6.46%, and 89.66%, respectively. The overall infection rates of non-CP, inflammatory CP, and non-inflammatory CP groups were 4.15%, 6.10%, and 3.65% in UU (p=0.612) and 6.85%, 7.22%, and 6.50% in UP (p=0.968), respectively. UU infection increased the risk of white blood cell (WBC) counts (≥5) in urine (p=0.005). In contrast, UP infections did not increase the risks of urethritis. Re-analysis from the 633 men who were excluded from urethritis effects did not reveal the associations between UU infection and the clinical characteristics of CP. Furthermore, the profiles from the National Institutes of Health-Chronic Prostatitis Symptom Index questionnaire and WBC counts in expressed prostatic secretion were similar among the non-CP and the two CP groups in each Ureaplasma infection. CONCLUSIONS: We found that UU may induce male urethritis. However, Ureapalsma species in urine were not definitively associated with the occurrence of CP.

A group of 180 men who visited Urology Department of Severance hospital, including 115 patients with nongonococcal urethritis (N.G.U.), 27 patients with prostatitis, 13 patients with gonococcal urethritis (G.U.) and 25 healthy medical student controls were investigated for the isolation of Ureaplasma urealyticum (T-strain mycoplasma) from the specimen of urethral discharge, urine and semen. Taylor-Pobinson media of T-broth and T-agar was used for the isolation of Ureaplasma urealyticum. To the best of our knowledge, the study on the culture of Ureaplasma urealyticum was reported for the first time in Korea. The following results were obtained: 1. The isolation rate of Ureaplasma urealyticum in nongonococcal urethritis (53.0%) revealed highest of those in the other three groups of prostatitis, gonococcal urethritis and control (40.7%, 38.4% and 16.0% respectively). 2. As for the specimens, urethral discharge revealed higher isolation rate of Ureaplasma urealyticum (54.6%)than first voided urine (50.0%). 3. The more consorts patients had, the higher positive culture rate of Ureaplasma urealyticum were revealed. The isolation rate in case of more than one causal in nongonococcal urethritis (71.1%) revealed much higher than in case of marital only (42.8%), one regular (41.1%) and one causal (41.0%). 4. 18.7% of isolation rate of Ureaplasma urealyticum revealed in patients with nongonococcal urethritis who visited the clinic in later than 4 weeks after the symptoms developed. However, the isolation rate in patients who visited within 4 weeks revealed 58.9%. The lower isolation rate of Ureaplasma in the late treatment seekers might be probably due to the suppression effect against Ureaplasma urealyticum from the possible previous self antibiotic treatment. 5. Attachment of Ureaplasma urealyticum mostly to the neck and head portion of the spermatozoa seemed to play a role to affect the motility of sperms.

We have experienced the female urethral syndrome in many patient, but we are embarrassed in identifying the exact cause of each case and searching for the treatment modalities. I thought there was a possibility of infection or local irritation by Ureaplasma urealyticum and Chlamydia trachomatis as an evoking factor of this syndrome. We have reviewed 32 women referred to Severance Hospital who complained irritative symptom of lower urinary tract without evidence of UTI and have come to the conclusion as follows 1. There was high isolation rate of ureaplasma urealyticum and Chlamydia trachomatis in female urethral syndrome. 2. There was no difference between isolation rate and age, or menopause. 3. There was high correlation between urethral and cervical isolation.

PURPOSE: We wanted to investigate the usefulness of Mycofast (MYCOFAST(R) Evolution 2, International Microbio, France) for Ureaplasma urealyticum (U. urealyticum) and Mycoplasma hominis (M. hominis) in association with nongonococcal genitourinary infections. MATERIALS AND METHODS: 530 patients visited our department for genitourinary infection symptoms or for the evaluation of sexually transmitted disease. The genital swabs were first vortexed in Mycofast transport broth. A volume of 100mul of liquid sample was innoculated to each well of the Mycofast broths and 0.5mul of liquid sample was innoculated to A7 agar culture media (International Microbio, France). The Mycofast broths were incubated at 35-37 degrees C for 36 hrs, and the A7 agar culture media was incubated for 4 days. We compaired Mycofast with A7 agar culture for the sensitivity, specificity, the positive and negative predictive values and the antibiotic susceptable profiles. RESULTS: Of the 530 samples submitted, 165 samples were positive by the A7 agar culture and 162 samples were positive by Mycofast. 157 samples were positive by both methods. Of the 365 samples that were negative by the A7 agar culture, 360 samples were also negative by the Mycofast. In this study, Mycofast had a sensitivity and specificity of 95% and 98%, respectively, and a positive and negative predictive value of 96% and 97%, respectively. The Mycofast drug susceptibility tests indicate a high susceptibility to doxycyclin as follows: U. urealyticum: 86.3%; M. hominis: 85.0% and both organisms with simultaneous isolation: 75.8%. CONCLUSIONS: Mycofast was an easy test to perform and it proved to be a practical and reliable method for isolating the Mycoplasma and Ureaplasma species for making the diagnosis of nongonococcal genitourinary infections, and it showed the added benefit of determining the limited susceptibilities of the isolated strains.

There is controversy regarding the roles of Ureaplasma urealyticum (U. urealyticum) colonization in the development of bronchopulmonary dysplasia (BPD). This study explored the association between U. urealyticum and bronchopulmonary dysplasia at 36 weeks post-menstrual age (BPD36). Studies published before December 31, 2013 were searched from Medline, Embase, Ovid, Web of Science, and Cochrane databases, with the terms "Ureaplasma urealyticum", "chronic lung disease", or "BPD36" used, and English language as a limit. The association between U. urealyticum colonization and BPD36 was analyzed with RevMan 4.2.10 software, using the odds ratio (OR) and relative risk (RR) for dichotomous variables. Out of the enrolled 81 studies, 11 investigated the BPD36 in total 1193 infants. Pooled studies showed no association between U. urealyticum colonization and subsequent development of BPD36, with the OR and RR being 1.03 (95% CI=0.78-1.37; P=0.84) and 1.01 (95% CI= 0.88-1.16, P=0.84), respectively. These findings indicated no association between U. urealyticum colonization and the development of BPD36.
