沙眼衣原体是一种专性细胞内嗜粘膜病原体,导致全球重要的人类感染。C.沙眼引起的沙眼是全世界可预防失明的主要原因,也是细菌性传播疾病的最常见原因。虽然眼生殖器感染可以用抗生素治疗,但需要疫苗来控制C。沙眼感染理想地,疫苗将提供针对大多数(如果不是全部)天然存在的抗原性不同血清变体的覆盖。亚单位疫苗,以防止眼生殖器疾病的发展,可以通过识别衣原体抗原,引发泛中和抗体,特别是在感染人群中的已知的危险因素。目前还没有客观的高通量体外试验来筛选人血清中的中和作用,以帮助鉴定这些抗原。本报告描述了一种测量C的客观、高通量的体外试验。沙眼中和抗体抗体介导的衣原体感染的中和在96孔微量滴定仪中进行,中和通过免疫染色固定的细胞,然后自动荧光分析进行定量。本报告表明,荧光分析C。沙眼感染与劳动密集型人工纳入计数直接相关。此外,本报告表明,荧光法可用于鉴定C。沙眼血清型和血清复合物特异性中和。这种客观、高通量的血清中和分析适用于人衣原体感染的流行病学研究、人临床疫苗试验和衣原体感染的临床前动物模型实验。
Chlamydia trachomatis is an obligate intracellular mucosotropic pathogen that causes human infections of global importance. C. trachomatis causes trachoma, the leading cause of preventable blindness worldwide, and is the most common cause of bacterial sexually transmitted disease. Although oculogenital infections are treatable with antibiotics, a vaccine is needed to control C. trachomatis infection. Ideally, a vaccine would provide coverage against most, if not all, naturally occurring antigenically distinct serovariants. The development of a subunit vaccine to prevent oculogenital disease could be advanced by identifying chlamydial antigens that elicit pan-neutralizing antibodies, particularly among infected human populations of known risk factors. There is currently no objective high-throughputin vitroassay to screen human sera for neutralization to aid in identification of these antigens. This report describes an objective, high-throughputin vitroassay that measures C. trachomatis-neutralizing antibodies. Antibody-mediated neutralization of chlamydial infection was performed in a 96-well microtiter format, and neutralization was quantified by immunostaining fixed cells followed by automated fluorometric analysis. This report shows that fluorometric analysis of C. trachomatis infection directly correlates to labor-intensive manual inclusion counts. Furthermore, this report shows that fluorometry can be used to identify C. trachomatis serovar- and serocomplex-specific neutralization. This objective, high-throughput analysis of serum neutralization is amenable to epidemiological studies of human chlamydial infection, human clinical vaccine trials, and preclinical animal model experiments of Chlamydia infection.
