摘要
轮状病毒多感染婴幼儿，它引起的腹泻是婴幼儿发病和致死的重要原因。但新生儿感染此病毒大多呈无症状型。为了解和证实这一特殊现象，作者采集了２个婴儿室足月正常新生儿无腹泻粪便样本１３１份，经聚丙烯酰胺凝胶电泳法（ＰＡＧＥ）和直接电镜法检测轮状病毒，发现感染所占百分比分别为３２．３％和２８．８％。感染株为同一电泳图型，电镜下可见典型的轮状病毒颗粒。从而证实了新疆某些医院婴儿室有轮状病毒无症状感染，并探讨了有关问题。
Rotavirus greatly
infects infants and children,and can result in death by diarrhea, However,neonatal infection by
rotavirus in mostly asymptomatic,In order to understand and prove this specialphenomenon ,
we gathered 131 healthy nondiarrhea newborn babies′fecal specimens in the nurseries oftwo
hospitals from March to May, 1992. These spocimens were examined bv PAGE and EM for
ro-tavirus。 The rate of the two nurseries′ infection was detected in 32.3%and 28.8%by PAGE
respec-tively。 The typical pollets of the rotavirus can seen by electron microscope(EM).This
report con-firmes that asymptomatic infection by rotavirus in neonate also occurred in
Xinjiang。
