直至较近期内,尚无确切证据证明病毒是腹泻疾病的重要原因。在发达国家中,大量调查显示,三分之二的腹泻病因不明。然而,近几年来,应用电子显微镜已发现新的病毒与胃肠类有关。1972年电镜首次证实是病毒。1964年所分离的和胃肠炎有关的Norwalk因子是一种27毫微米的细小病毒样颗粒。1973年,Bishop等应用电镜,报告第二种病毒,它与腹泻疾病有关。这种病毒就是轮状病毒。在过去几年中,轮状病毒已被认为是儿童时期胃肠炎的单一而最重要的原因。本文将总结近五年来有关轮状病毒的资料。
Until recently, there is no conclusive evidence that the virus is an important cause of diarrheal diseases. In developed countries, a large number of surveys show that two thirds of the causes of diarrhea are unknown. However, in recent years, new viruses have been found to be associated with the gastrointestinal tract using electron microscopy. Electron microscope for the first time in 1972 confirmed that the virus. The Norwalk factor associated with gastroenteritis isolated in 1964 is a 27-nm parvovirus-like particle. In 1973, Bishop and other electron microscopy, report the second virus, which is related to diarrhea disease. This virus is rotavirus. In the past few years, rotavirus has been considered the single and most important cause of childhood gastroenteritis. This article will summarize the rotavirus data for the last five years.
