2、ObjectiveTo investigate the etiological surveillance results of children with diarrhea hospitalized in AnhuiChildrens Hospital.MethodsThe fecal samples of 1 334 children with diarrhea hospitalized in Anhui ChildrensHospital from 2016 to 2021 were detected using traditional method，the nucleic acids o

6、downward trend over time in the detection rate of pathogenic bacteria in hospitalized children with diarrhea.The detection rates of pathogenic bacteria，viruses and total pathogens were statistically different in children withdiarrhea in different age groups（P0.05），with the highest detection rate of
7、pathogenic bacteria in children aged 11-14 years（30.45%）and the highest detection rate of viruses in children aged 0-5 years（43.37%）.The detection疾病监测安徽省儿童医院 20162021 年住院腹泻患儿病原学监测张蔷，邓芳安徽医科大学附属省儿童医院（安徽省儿童医院）感染科，安徽 合肥230001摘要：目的调查安徽省儿童医院住院腹泻患儿病原学监测结果。方法采用传统法检测安徽省儿童医院20162021年1 334例住院腹泻患儿粪便细菌，实时荧光PCR检测
8、病原体核酸（包括沙门菌、致泻性大肠杆菌、志贺菌、小肠结肠炎耶尔森菌、类志贺邻单胞菌、轮状病毒、诺如病毒、札如病毒、腺病毒、星状病毒），并分析不同年份、年龄、性别、居住地及不同季节的住院腹泻患儿病原菌分布特点。结果20162021年共收集病例1 334例，在1 334份粪便标本中检出770株病原微生物，检出率为57.72%，其中致病菌290株（21.74%），病毒480株（35.98%）。检出率最高的致病菌为沙门菌（7.35%）和致泻性大肠杆菌（7.12%），检出率最高的病毒是轮状病毒（17.32%）和诺如病毒（10.72%）。2017年病原菌检出率最高，为66.10%，2021年病原菌检出率最
9、低，为50.38%，随时间的推移，住院腹泻患儿病原菌检出率下降。不同年龄段腹泻儿童病原菌、病毒及总病原体检出率差异均有统计学意义（P0.05）。不同居住环境腹泻患儿致病菌、病毒及总病原菌检出率比较，差异均无统计学意义（P0.05）。不同季节腹泻患儿致病菌、病毒及总病原体检出率差异均有统计学意义（P0.05）and different living environments（P0.05）.The detection rates of pathogenic bacteria，viruses and total pathogens showed statistical difference in d
10、iarrhea children in different onset seasons，with higherdetection rate of pathogenic bacteria in summer and autumn than in spring and winter（30.04%，32.76%vs.18.78%，14.55%）and higher detection rate of viruses in winter than in the other three seasons（47.19%vs.29.10%，30.45%，29.74%）.ConclusionFrom 2016
11、to 2021，the pathogens detected in the fecal samples of hospitalized diarrheachildren in Anhui Childrens Hospital were mainly viruses.Viruses detection rates were high in diarrhea childrenaged 0-5 years and bacteria detection rates were high in diarrhea children aged 11-14 years.With age，the overalld
