OBJECTIVETo discuss the main parasitic position of Ureaplasma urealyticum (Uu) and Mycoplasma hominis (Mh) in female genital tract.

METHODSUsing the standard aseptic cotton swab to collect secretion in vaginal fornix and orificium internum uteri, to culture Uu and Mh in Mycoplasma ID medium of France Bio-Merieux Co. According to double-direction quality reaction sequential test design, detection results of different position were analyzed.

RESULTSTotal positive and > or = 10(4) ccu/ml positive of Uu in vaginal fornix were significantly higher than that in orificium internum uteri. Total positive of Mh in vaginal fornix was significantly higher than that in orificium internum uteri as well.

CONCLUSIONIn order to raise the detectable rate of Mycoplasma, we suggested that the secretion in vaginal fornix position be collected.

OBJECTIVETo investigate the infection and the drug resistance status of mycoplasma and chlamydiae in genitourinary tracts of children with suspected nongonococcal urethritis (NGU) and provide information for clinical rational administration of antimicrobial agents.

METHODSSamples of genitourinary tract secretion from 146 children who were suspected of having nongonococcal urethritis or colpitis were collected and tested for mycoplasma via culture and for chlamydia with antigen detection. Meanwhile, susceptibility test was carried out on the samples which were positive in mycoplasma cultivation. Chlamydia antigen was detected by the polymer conjugate-enhanced (PCE) indirect enzyme immunoassay (EIA) (IDEIA PCE Chlamydia; DAKO). The mycoplasma culture medium was produced by Nanjing Liming Biological Products Co,. Ltd. Antibiotics used for susceptibility test were erythromycin, roxithromycin, josamycin, leucomycin, meleumycin, rovamycin, azithromycin, clarithromycin, cycloate erythromycin, and clindamycin.

RESULTSFifteen samples were positive for Chlamydia trachomatis (Ct) by antigen detection (10.3%), 82 samples were positive in mycoplasma cultivation (56.2%), and among the 82 samples, 58 were positive for Ureaplasma urealyticum (Uu, 39.7%), 9 were positive for Mycoplasma hominis (Mh, 6.2%), and 15 were positive for Uu and Mh (10.3%). Of all the samples, 4 were positive for both Uu and Ct (2.7%). The rates of drug resistance of the 10 commonly used antibiotics were as follows: erythromycin 32.9%, roxithromycin 41.5%, josamycin 19.5%, leucomycin 22.0%, meleumycin 28.0%, rovamycin 30.5%, azithromycin 37.8%, clarithromycin 26.8%, davercin 24.4%, and clindamycin 26.8%, respectively. The results indicated that drug resistance rates of josamycin and leucomycin were the lowest, and the rates of roxithromycin and azithromycin were the highest.

CONCLUSIONSThe infection rates of mycoplasma and chlamydia in children suspected NGU were high. Mycoplasma showed drug resistance to a different degree to 10 common antibiotics. The results of chemosensitivity showed that josamycin had the highest susceptibility rate.

BACKGROUND: To investigate the risk factors for vaginal infections and antimicrobial susceptibilities of vaginal microorganisms among women who experienced preterm birth (PTB), we compared the prevalence of vaginal microorganisms between women who experienced preterm labor (PTL) without preterm delivery and spontaneous PTB. METHODS: Vaginal swab specimens from 126 pregnant women who experienced PTL were tested for group B streptococcus (GBS), Mycoplasma hominis, Mycoplasma genitalium, Ureaplasma urealyticum, Chlamydia trachomatis, Trichomonas vaginalis, Neisseria gonorrhoeae, Treponema pallidum, herpes simplex virus (HSV) I and II, and bacterial vaginosis. A control group of 91 pregnant women was tested for GBS. Antimicrobial susceptibility tests were performed for GBS, M. hominis, and U. urealyticum. RESULTS: The overall detection rates for each microorganism were: U. urealyticum, 62.7%; M. hominis, 12.7%; GBS, 7.9%; C. trachomatis, 2.4%; and HSV type II, 0.8%. The colonization rate of GBS in control group was 17.6%. The prevalence of GBS, M. hominis, and U. urealyticum in PTL without preterm delivery and spontaneous PTB were 3.8% and 8.7% (relative risk [RR], 2.26), 3.8% and 17.3% (RR, 4.52), and 53.8% and 60.9% (RR, 1.13), respectively, showing no significant difference between the 2 groups. The detection rate of M. hominis by PCR was higher than that by culture method (11.1% vs. 4.0%, P=0.010). The detection rates of U. urealyticum by PCR and culture method were 16.7% and 57.1%, respectively. CONCLUSIONS: There was no significant difference in the prevalence of GBS, M. hominis, and U. urealyticum between the spontaneous PTB and PTL without preterm delivery groups.

In order to investigate the susceptibility of mixed infection of Ureaplasma Urealyticum (UU) and Mycoplasma Hominis (MH) to 7 kinds of antimicrobial agents and comparison with that of UU infection in NGU patients, the in vitro susceptibility was determined by using microdilution method. The positive results were analyzed. The results showed that the sequence of susceptibility to 7 kinds of antimicrobial agents for both UU infection group and UU-MH mixed infection group was almost the same from the highest susceptibility to the lowest accordingly: Josamycin, Doxycycline, Minocycline, Sparfloxacin, Roxithromycin, Ofloxacin and Azithromycin. The total drug resistance rate for UU-MH mixed infection group (97.67%) was significantly higher than that for UU infection group (44.67%, P < 0.01). The highest drug resistance rate in UU group and UU-MH mixed infection group was 31.33% (Ofloxacin) and 90.48% (Azithromycin) respectively. UU-MH mixed infection showed an increased drug resistance and changes of drug resistance spectrum.

OBJECTIVETo observe the prevalence and drug tolerance of mycoplasma(Ureaplasma urealyticum and Mycoplasma hominis) in patients with urogenital inflammation.

METHODSThree thousand and fifty-five patients with urogenital inflammation such as non-gonococcal urethritis(NGU), chronic prostatitis or pelvic inflammation from 1999 to 2003 were included. The results of mycoplasma culture and drug sensitivity test were analyzed.

RESULTSA total of 992(32.5%) cases were mycoplasma positive in the 3,055 patients, and there was no significant difference in the yearly positive percentage in the 5 years (P < 0.05). Among them, 701(70.7%) were infected with Ureaplasma urealyticum, 44(4.4%) with Mycoplasma hominis, and 247(24.9%) with both Ureaplasma urealyticum and Mycoplasma hominis, the Ureaplasma urealyticum infection rate being much higher than that of Mycoplasma hominis and mixed infection (P < 0.01). The high colony counting(> or = 10(4) cfu/ml) in Ureaplasma urealyticum infection patients accounted for 76.7%, while Mycoplasma hominis infection represented only 18.2%. The results of drug tolerance test showed a higher sensitivity to doxycycline, pristinamycin, josamycin and tetracycline (94.3%, 96.6%, 86.5% and 97.4% respectively), and a lower sensitivity to erythromycin and ofloxacin (54.8% and 29.4% respectively).

CONCLUSIONSUreaplasma urealyticum and Mycoplasma hominis should be detected simultaneously and the drug tolerance test is needed for the selection of appropriate antibiotics.

OBJECTIVETo investigate the distribution and the antimicrobial resistance of the bacteria, mycoplasma and Chlamydia trachomatis isolated from the prostatic secretion of infertile men with chronic prostatitis, and to provide clinicians with grounds for choosing antibiotic agents.

METHODSThe bacteria obtained were isolated and identified, the Chlamydia trachomatis was detected by FLO-PCR, and the results were analysed statistically.

RESULTSIn 1 186 specimens of EPS, the total positive rate of isolates was 51.7%. Among them, there were 364 strains of gram-positive coccus, 20 gram-negative bacillus, 5 other strains and 157 mycoplasma, including 116 Ureaplasma urealyticum and 41 Mycoplasma hominis, and 67 Chlamydia trachomatis DNA. As for the isolated staphylococci, their antimicrobial resistance was the lowest against vancomycin (0.0%), but the highest against penicillins (76.9%-100%); for the Streptococcus agalactiae, it was the highest against erythromycin and clindamycin (100%), and the lowest against beta-lactams, aminoglycosides, trimethoprim + sulfamethoxazole, rifampin and vancomycin (0.0%); for the Ureaplasma urealyticum, it was the highest against ciprofloxacin (59.5%), and the lowest against josamycin, tetracycline and fosfomycin (1.7%); for the Mycoplasma hominis, it was the highest against erythromycin (100%), and the lowest against doxycycline and fosfomycin (0.0%).

CONCLUSIONBacteria, mycoplasma and Chlamydia trachomatis are the possible etiological factors of male infertility. Isolated bacterial strains differ greatly in their resistance against different antibiotics.

OBJECTIVETo explore the significance of clue cells in the diagnosis of male urogenital infection.

METHODSUrethra swabs or prostatic fluid of 264 male outpatients were collected and smeared directly on the slice to find clue cells under the ultramicroscopy. Meanwhile, the positive patients' spouses were detected for bacterial vaginosis (BV).

RESULTSThe positive rates of the urethra swabs and the prostatic fluid were 5.1% (11/215 ) and 2.0% (1/49), respectively. Nine cases in 11 of the patients' spouses (81.8%) were diagnosed as BV.

CONCLUSIONBV pathogen can attack and attach to the epithelia of male genitals to form clue cells. Clue cells positive, along with clinical symptoms, contribute to the diagnosis of male urogenital bacterial infection.
