感染性腹泻目前仍然是对人类健康威胁最大的疾病之一,由于过去对引起腹泻的病因知得甚少,分离病原体的阳性率又很低,因而妨碍了防治工作的有效进行。近十年来国外对本病的研究有显著的进展,现将主要方面综述于下,以供参考。病原学病毒轮状病毒它是引起婴幼儿腹泻最常见的病毒。通过中和试验或酶联免疫吸附(ELISA)试验可区分为两个主要血清型及若干亚型。由于人类轮状病毒不易在细胞培养中繁殖,故动 Infectious diarrhea is still one of the most threatening diseases to human health at present. Since the cause of diarrhea was little known in the past and the positive rate of isolated pathogens was very low, the prevention and treatment work was effectively prevented. The past 10 years abroad, the study of this disease has made significant progress, the main aspects are summarized below for reference. Etiology Viruses Rotavirus is the most common virus that causes diarrhea in infants and young children. Through the neutralization test or enzyme-linked immunosorbent (ELISA) test can be divided into two major serotypes and several subtypes. As human rotavirus is not easy to breed in cell culture, so move
