【摘要】：目的了解无锡市门诊就诊腹泻病例中主要腹泻病毒感染情况。方法连续一年逐月采集无锡市腹泻监测哨点医院门诊腹泻病例的粪便样本,采用实时荧光PCR方法对收集的样本检测诺如病毒(NV)、轮状病毒(RV)、肠道腺病毒(EADV)、札如病毒(SPAV)和星状病毒(ASTV)的核酸,分析病原构成和季节分布变化。结果 291份腹泻样本中,共检出目标病毒核酸阳性79份,总检测阳性率为27.1%,阳性率由高到低依次为NV 15.5%、RV 8.2%、ASTV2.1%、SPAV 1.0%、EADV 0.3%。NV全年各月都有检出,其中GⅡ型占88.9%(40/45),GⅠ型占11.1%(5/45)。这些病毒感染有明显的季节特征,基本表现为冬春季发病高峰的特征。结论无锡地区冬春季节腹泻中病毒性感染值得重视,目前以NV和RV为主,同时,应加强监测优势型别的变化。
[Abstract]:Objective to investigate the prevalence of main diarrhea virus (CDV) infection in outpatients with diarrhea in Wuxi. Methods fecal samples of diarrhea cases in outpatient clinic of sentinel hospital in Wuxi were collected month by month for one year. The nucleic acids of NVV, RV, EADVV, SPAV and ASTVV were detected by real-time fluorescence PCR, and the pathogen composition and seasonal distribution were analyzed. Results of the 291 diarrhea samples, 79 were positive for target virus nucleic acid, and the total positive rate was 27.1and the positive rate was NV 15.5and RV 8.2in turn. The SPAV 1.0% EADV 0.3%.NV was detected every month of the whole year, and G 鈪，
