摘    要:目的分离鉴定重症手足口病患者气管插管吸出液标本的EV71病毒株。方法将采集的标本过滤除菌接种于MA104细胞,出现细胞病变效应(CPE)后提取培养上清液中的RNA,用国家标准检测引物进行RT-PCR鉴定;用特异性引物进行PCR获得VP1全序列,测序后以MEGA4软件与各血清型代表株VP1序列进行分析并构建分子进化树。结果接种标本3 d后细胞出现CPE,经RT-PCR鉴定为EV71,对其VP1全序列进行测定分析后,确定其为C4亚型,并绘制了分子进化树。结论手足口病患者下呼吸道分泌物EV71的分离鉴定,为手足口病肺损伤发病机制的研究提供了依据。

Abstract:Objective To isolate and identify enterovirus 71(EV71) in the endotracheal aspirate specimen from a patient with hand-foot-mouth disease(HFMD).Methods The endotracheal aspirate specimen was inoculated in MA104 cells.Total RNA was extracted after the cytopathic effect(CPE) was observed,and the national standard primer was used to detect EV71 by RT-PCR.The VP1 complete sequence was obtained by PCR and then sequenced.An evolutionary tree was structured by MEGA4.Results Cells showed CPE 3 days after inoculation.The virus was identified as EV71 by RT-PCR.After the VP1 complete sequence was analyzed,the virus was confirmed as the C4 serotype,and the evolutionary tree was drawn by MEGA4.Conclusions For the first time,EV71 was isolated from lower respiratory tract secretion from HFMD patients,providing a basis for the study of the pathogenesis of lung tissue injury in HFMD patients.
Keywords:Enterovirus A  human  Hand  foot and mouth disease  Viruses cultivation
