解脲脲原体感染与精子凋亡的关系 总被引:3,自引:0,他引:3
解脲脲原体(Uu)是泌尿生殖道感染的常见病原体,国内外研究表明Uu感染与某些男性不育密切相关,但其机制尚未完全明了。其感染对精子凋亡影响研究报道尚少.特采用流式细胞术(FCM)对精液Uu培养不同结果的男性作精子凋亡率检测,探讨不育机理。 相似文献

目的研究解脲脲原体(Uu)与自然流产和药物不全流产的关系,探讨Uu与宫内感染的可能机制。方法采用分离培养分别对45例自然流产和27例药物不全流产(试验组)和31例人工流产(对照组)的母亲宫颈分泌物及胚胎组织进行Uu检测,分别对部分试验组和对照组进行超薄切片,并与其培养物负染电镜检查相比较。结果试验组流产组织中Uu检出率分别为53.3%和63%,与对照组相比较,具显著性差异(p<0.001,p<0.001);经超薄切片观察,试验组流产组织的绒毛膜下滋养层细胞周围见大量的Uu颗粒及空泡内增殖的子细胞,并与其流产组织中阳性培养物经负染后的颗粒相似。而对照组胚胎流产组织中无此颗粒。结论绒毛膜下滋养层Uu增殖这一结果充分证实了Uu是引起宫内感染的病原体之一。 相似文献

A recent phylogenetic analysis of Ureaplasma urealyticum resulted in the proposal to divide their 2 biovars into species. We used PCR to compare the distribution of species and the presence of the tet(M) and int-Tn resistance determinants in 63 strains of Ureaplasma spp. isolated from the amniotic fluid of patients with an adverse pregnancy outcome and in 22 strains obtained from the lower genital tract of healthy pregnant women. We also determined the antimicrobial susceptibility of the organisms to erythromycin and tetracycline. U. parvum was the most frequent Ureaplasma species detected in our study. Thus, 50/63 (79.4%) invasive isolates and 17/22 (77.3%) lower genital tract isolates corresponded to U. parvum, whereas 12/63 (19%) invasive isolates and 4/22 (18.2%) non-invasive strains corresponded to U. urealyticum. A mixture of species was found in 2 women. We found no significant differences in the antimicrobial susceptibility of isolates according to species or origin of isolation. Sixty-two strains of Ureaplasma spp. (74.7%) were susceptible to erythromycin, and 21 strains (25.3%) were intermediately susceptible. Sixty-eight isolates (81.9%) were susceptible to tetracycline, 2 strains (2.4%) were intermediate and 13 strains (15.7%) were resistant. DNA sequences related to the tet(M) determinant and the int-Tn gene were found in all tetracycline-resistant isolates. 相似文献

We report of a case of severe disseminated U. urealyticum infection in a 35-y-old kidney transplanted patient with CVID. Routine microbiological tests were negative. Six weeks after admission, abscess material was grown on Mycoplasma culture medium yielding U. urealyticum in high titres. The patient responded promptly to appropriate antibiotics. 相似文献

Objective. To determine the prevalence of genitourinary mycoplasma infection in women with systemic lupus erythematosus (SLE). Methods. Urine specimens from 49 patients with SLE and 22 patients with chronic fatigue syndrome (CFS) were cultured for mycoplasma. Patient records were reviewed for medical history and SLE disease activity. Results. Sixty-three percent of the SLE patients were culture positive, compared with 4.5% of the CFS patients (P < 0.001). Neither corticosteroid treatment, SLE activity, nor age accounted for this difference. Conclusion. Genitourinary mycoplasma colonization occurs significantly more frequently in SLE than in CFS. 相似文献

Titers of mycoplasmacidal antibody to the human genital mycoplasmas Ureaplasma urealyticum and Mycoplasma hominis were determined using genital isolates from pregnant patients as antigens and comparing these isolates with the 11 prototypic reference strains for U. urealyticum and the seven reference strains for M. hominis. Virtually all titers that were detected with use of the patient's own isolates were detected by the 11 reference strains of U. urealyticum and by the seven reference strains of M. hominis. Serologic surveys of pregnant women who harbored either or both mycoplasmas in vaginal cultures indicated that antibody to M. hominis was found more commonly than antibody to U. urealyticum. It was demonstrated that significant postpartum rises in titers of antibody to M. hominis were correlated with the presence of these mycoplasmas in genital cultures. Postpartum rises in titer of antibody were particularly likely to occur in women with low titers of mycoplasmacidal antibody in serum at the time of delivery. Approximately 88% of the women who were colonized with M. hominis showed significant changes in titer of antibody to M. hominis throughout an apparently normal pregnancy; only 40% of the women who were colonized with U. urealyticum showed such changes in titers to U. urealyticum. Statistical analysis showed that mean log titers of antibody to both mycoplasmas at the first prenatal visit were significantly associated with the number of pregnancies experienced by these women. 相似文献
