2013-2014年福州市环境污水应用于肠道病毒监测结果分析
Enterovirus distribution in environmental sewage in Fuzhou City, 2013-2014
摘要
Abstract
In order to explore the significance of enterovirus environmental surveillance of sewage,two sewage treatment plants in Fuzhou City were selected as sentinel surveillance sites.One sewage sample was collected from entrance of each plant every month,and total 48 samples were studied from 2013 to 2014 in Fuzhou City.Using the RD,L20B and Hep-2 cell lines to isolate the viruses,44 of the 48 sewage samples (91.67％) were positive,268 strains were isolated which covered at least 22 enterovirus serotypes.The peak season of virus isolation from sewage was in February and July which was two months earlier than patient surveillance.Eehovirus type 7 (Echo 7) was the predominant serotype in 2013 with 58 isolations (43.61％),and in 2014 echovirus type 6 (ECHO 6) became the predominant serotype with 85 isolates (62.96％),among the strains isolated from sewage sample.Phylogenetic analysis found that the predominant serotype Echo 6 and Echo 7 isolated from sewage were more diversified than that from clinical cases during the same period,and were high homology with isolates form patients which belong to same branch in phylogenetic tree.In conclusion,enterovirus environmental sewage surveillance is an effective approach,and could be more sensitive than patient surveillance.关键词
