The two-hour Rapid SST strip (DMS Laboratories, Inc.) was compared with our standard screening system (triple sugar iron agar, lysine iron agar, and urea) for enteric pathogens. We tested 50 stock cultures of enteric pathogens and 213 stool cultures received in the Barnes Hospital Clinical Microbiology Laboratory over a two-month period. All enteric pathogens from the stock cultures and clinical specimens were identified correctly with the Rapid SST system. More false-positive reactions were observed with the Rapid SST system (34%) than with the conventional system (23%). However, the costs associated with using both systems were equivalent and the test results were available one day faster with the Rapid SST system. Thus, the Rapid SST is a rapid, accurate, and cost-effective method for screening stool specimens for enteric pathogens.
将两小时快速SST试纸条（DMS实验室公司）与我们用于肠道病原体筛查的标准系统（三糖铁琼脂、赖氨酸铁琼脂和尿素）进行了比较。在两个月的时间里，我们检测了50株肠道病原体的储备培养物以及巴恩斯医院临床微生物实验室收到的213份粪便培养物。使用快速SST系统能够正确鉴定出储备培养物和临床标本中的所有肠道病原体。与传统系统（23%）相比，快速SST系统观察到更多的假阳性反应（34%）。然而，使用这两种系统的成本相当，并且快速SST系统能提前一天获得检测结果。因此，快速SST是一种用于筛查粪便标本中肠道病原体的快速、准确且具有成本效益的方法。
