Abstract

A total of 1107 fecal samples from young children admitted to hospital for acute enteric infection in January to December 2007 were tested for astroviruses. Astroviruses were detected in 64 (5.8%) of the 1107 stool samples, only 50% of them were found as monoinfections. Astroviruses were recorded throughout the year; however, no seasonality for this infection could be ascertained. Cases of astrovirus infection were mainly observed in infants under one year of age (90%). Astroviruses were typed sequencing the ORF2 fragment; only HAstV-1 and HAstV-2 were found in Novosibirsk.

摘要

对2007年1月至12月因急性肠道感染入院的幼儿的1107份粪便样本进行了星状病毒检测。在1107份粪便样本中，有64份（5.8%）检测到星状病毒，其中仅50%为单一感染。星状病毒全年均有检出；然而，无法确定这种感染的季节性。星状病毒感染病例主要见于1岁以下婴儿（90%）。通过对开放阅读框2片段进行测序对星状病毒进行分型；在新西伯利亚仅发现了HAstV-1和HAstV-2。
