线虫秀丽线虫是一种独特的整体动物模型系统,用于鉴定具有体内抗感染特性的小分子。线虫可感染多种人类病原体,包括粪肠球菌,这是一种重要的人类医院病原体,死亡率高达37%,对抗生素的耐药性日益增强。在这里,我们描述了一种自动化的高通量筛选,包括37,200种化合物和天然产品提取物,用于提高感染粪肠球菌的线虫的存活率。该屏幕使用机器人将活体、受感染的动物准确地分配到384孔板中,并使用自动显微镜和图像分析来生成定量、高含量的数据。我们鉴定了28种化合物和提取物,这些化合物和提取物以前没有报道过具有抗菌特性,其中包括6个结构类别,可以治愈受感染的线虫动物,但不会影响病原体的体外生长,因此其作用机制与目前临床使用的抗生素不同。我们的多功能和强大的筛选系统可以很容易地适用于其他全动物检测,以探索广泛的生物过程。
The nematode Caenorhabditis elegans is a unique whole animal model system for identifying small molecules with in vivo anti-infective properties. C. elegans can be infected with a broad range of human pathogens, including Enterococcus faecalis, an important human nosocomial pathogen with a mortality rate of up to 37% that is increasingly acquiring resistance to antibiotics. Here, we describe an automated, high throughput screen of 37,200 compounds and natural product extracts for those that enhance survival of C. elegans infected with E. faecalis. The screen uses a robot to accurately dispense live, infected animals into 384-well plates, and automated microscopy and image analysis to generate quantitative, high content data. We identified 28 compounds and extracts that were not previously reported to have antimicrobial properties, including 6 structural classes that cure infected C. elegans animals but do not affect the growth of the pathogen in vitro, thus acting by a mechanism of action distinct from antibiotics currently in clinical use. Our versatile and robust screening system can be easily adapted for other whole animal assays to probe a broad range of biological processes.
