【摘要】 <正> 轮状病毒是婴幼儿腹泻的主要病原,在我国亦广泛流行,根据病毒基因组的电泳分析,可以研究其分子流行病学的规律。文献报道该病毒在流行区往往以一个电泳型感染为主,我们对长春地区1984～1985年和1985～1986年两个冬季流行的婴幼儿腹泻轮状病毒基因组PAGE分析的结果,也表明两个冬季都是以电泳长型感染为主,其中优势株与本室更多还原

【Abstract】 Electrophoretic typing has been an useful method for epidemiological studies of rotavirus infection. Analysis of RNA patterns of rotavirus isolates from stools of young children with acute gastroenteritis in Changchun revealed that the long electrophoretype predominated during 1984-1985 and 1985-1986 winter seasons. Besides,some minor variations were observed among the isolates. Probably two strains appeared to be predominant during the period under study. In comparison with standard strains, the RNA profiles of the predominants appeared to be closer to that of serotype 4.更多还原
