83年12月～84年4月。用聚丙烯酰胺凝胶电泳技术研究了采自河南省部分地区156例急性腹泻小儿.13例健康成人和5例健康儿童的粪便标本.70例病儿标本呈现轮状病毒 RNA 图式.依基因片段迁移率的变化.可分为长短两个电泳型(L 和 S 型)以及十个亚电泳型(L1—5.Sta1bS2a.S2b.S3)郑州市优势电泳型为 S2a 和 S2b.新乡地区和通许县分别为 L3和 S1b.混合电泳显示.L4和 L5出现的附加区带.可能由混合感染造成.还从健康成人粪便中检出 S2a 型轮状病毒.
December 83 to April 1984. The stool samples from 156 cases of acute diarrhea children, 13 healthy adults and 5 healthy children from parts of Henan province were studied by polyacrylamide gel electrophoresis.The rotavirus RNA patterns of 70 cases of children were presented.According to the gene Fragment mobility changes can be divided into the length of two electrophoresis type (L and S type) and ten sub-electrophoresis type (L1-5.Sta1bS2a.S2b.S3) Zhengzhou superior electrophoresis type S2a and S2b. Xinxiang region and Tongxu County were L3 and S1b, respectively.Mixing electrophoresis showed that additional bands appeared in L4 and L5, possibly caused by mixed infections, and S2a-type rotavirus was also detected in healthy adult feces.
