在研究人类胃肠炎的病因时，电子显微镜和相关技术已导致识别出以前未通过常规细胞培养程序检测到的新病毒制剂。自20世纪70年代初以来，电子显微镜和免疫电子显微镜已鉴定出两大类胃肠炎病毒:诺沃克病毒和轮状病毒。本文介绍了这两种病毒类型以及与胃肠炎相关的其他病毒的检测。描述了华盛顿、宾夕法尼亚和乔治亚州与诺沃克病毒相关的水传播病毒性胃肠炎暴发。讨论了瑞典、巴西、科罗拉多、苏联、东德、中国和以色列与轮状病毒相关的水传播疫情。描述了在科罗拉多州一次胃肠炎暴发的调查中检测到的雪山病原体病毒的鉴定。 包括49个参考文献、表格和图表。

In studying the causes of human gastroenteritis, electron microscopy and related techniques have led to the identification of new viral agents that had previously escaped detection by routine cell culture procedures. Since the early 1970's, two major groups of gastroenteritis viruses have been identified by electron microscopy and immune electron microscopy: the Norwalk virus and rotavirus. This article addresses the detection of these two virus types and other viruses associated with gastroenteritis. Outbreaks of waterborne viral gastroenteritis associated with the Norwalk virus in Washington, Pennsylvania, and Georgia are described. Waterborne outbreaks in Sweden, Brazil, Colorado, the Soviet Union, East Germany, China, and Israel associated with rotavirus are discussed. The identification of the Snow Mountain Agent virus detected during an investigation of a gastroenteritis outbreak in Colorado is described. Includes 49 references, tables, figure.
