免疫荧光法与 Giemsa 氏法检测沙眼衣原体的比较

本文用免疫荧光法与 Giemsa 氏法检测明显沙眼患者,两法阳性率相差无几。但在临床肉眼观察认为正常时,其阳性率分别为24.77%及11.58%(P<0.05),差异有显著意义,表明免疫荧光法检测早期沙眼较 Giemsa 氏法敏感。临床认为正常眼,经实验室检查25.56%为阳性,说明开展沙眼的实验室诊断是必要的。     

微量沙眼衣原体组织培养法的建立及临床应用

建立了微量沙眼衣原体组织培养法，并应用于不同人群的生殖道标本的沙眼衣原体培养。结果生殖道沙眼衣原体培养的阳性率：男性尿道炎患者１４７％（９／６１）；正常孕妇３３％（７／２１０）；急性和亚急性盆腔炎女性患者６７％（７／１０４）；性病门诊患者１８２％（４９／２６９）。由于９６孔培养板及倒置荧光显微镜的应用，微量培养法试剂用量少、过程简化；自制的抗沙眼衣原体单克隆抗体大大降低了培养后的染色成本，适用于大宗标本。     

The occurrence of Chlamydia trachomatis in the semen of men participating in an IVF programme

Chlamydia trachomatis is one of the most common causative agentsof sexually transmitted diseases. The authors studied the occurrenceof C.trachomatis in the semen of 184 asymptomatic men participatingin the IVF programme. Twenty-six (14.1%) of the 184 tested werepositive for C.trachomatis, these patients and their wives receivingdoxycycline capsules twice, 100 mg on the first day and 100mg/day for the following 13 days. This treatment was effectivein 88.5% of the cases and in the rest, treatment continued witherithromycin 250 mg four times/day for 2 weeks. The authorscompared the semen parameters (cell count, motility, morphology,bovine mucus penetration and hypo-osmotic swelling test) inthe infected and non-infected groups and observed no significantdifference between these two groups     

Chlamydia trachomatis: time for screening?

Genital Chlamydia trachomatis infection is the leading cause of bacterial sexually transmitted disease in industrialised countries, particularly among young people. The consequences of chlamydial infection may involve urethritis, cervicitis, pelvic inflammatory disease, ectopic pregnancy, tubal factor infertility, epididymitis and prostatitis. In addition, chlamydial infection increases the risk of acquisition of human immunodeficiency virus and has been associated with cervical cancer. Although screening programmes exist in a number of countries, the continuously increasing prevalence of chlamydial infections demonstrates the necessity for health authorities to establish effective screening policies, and the importance of defining a comprehensive European screening policy is emerging.

体外基因扩增技术检测上呼吸道炎症局部脱落细胞中肺炎衣原体DNA

为快捷诊断上呼吸道肺炎衣原体感染，用肺炎衣原体ＰｓｔＩ４７４片段特异性聚合酶链式反应（ｐｏｌｙｍｅｒａｓｅｃｈａｉｎｒｅａｃｔｉｏｎ，ＰＣＲ）法检测了急性上呼吸道炎症患者局部拭子标本。同时以微量免疫荧光法检测了血清中肺炎衣原体特异性抗体。结果在１７５例患者拭子标本中，ＰＣＲ阳性４９例，阳性率２８％；荧光抗体阳性４５例，阳性率２５．７％。两者相符率９１．８％。表明肺炎衣原体ＰｓｔⅠ４７４片段特异性ＰＣＲ法检测鼻咽喉部肺炎衣原体感染是一个较敏感和特异的方法     

肺炎衣原体感染与动脉粥样硬化

动脉粥样硬化性心脑血管疾病已经成为危害人类健康的头号杀手。与动脉粥样硬化相关的危险因素也成为研究的焦点,除高脂血症﹑、高血压、糖尿病、吸烟、年龄、家族遗传病史等动脉粥样硬化的传统危险因素外,近年来有越来越多的研究显示肺炎衣原体对动脉粥样硬化的发生和发展起到了至关重要的作用。众多关于肺炎衣原体感染与动脉粥样硬化的研究被报道。学者们从临床检测、动物实验、细胞分子水平等方面来证实肺炎衣原体与动脉粥样硬化的相关性。     

Performance of cobas® 4800 and m2000 real-time™ assays for detection of Chlamydia trachomatis and Neisseria gonorrhoeae in rectal and self-collected vaginal specimen

A prospective, multicenter trial was designed to compare the performance characteristics of the cobas® 4800 (Roche Diagnostics, Indianapolis, IN, USA) and m2000 real-time™ (Abbott Molecular Inc., Des Plaines, IL, USA) assays for detection of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) in rectal and self-collected vaginal swabs. Rectal (n = 234) or self-collected vaginal swabs (n = 687) were obtained from consenting individuals visiting their general practitioners, dermatologists, gynecologists, sexually transmitted disease clinics, or family planning centers from May 2010 to February 2011. High concordance rates (≥96%) were observed between the cobas® 4800 and m2000 real-time™ assays for CT/NG detection in both rectal and self-collected vaginal swabs. The performance profiles confirm the usefulness of both kinds of swab types for CT and NG detection using described nucleic acid amplification tests assays. Based on this study, rectal and self-collected vaginal swabs offer a noninvasive alternative, which may improve screening for CT and NG infections.
