摘　　要：目的了解广州地区小儿腹泻的主要病原菌及耐药情况,为临床诊治和流行病学调查提供相应依据。方法对就医于广州市儿童医院,临床疑似细菌感染性腹泻的小儿大便标本进行临床细菌学检验。结果小儿腹泻的易感人群为婴幼儿,好发于夏、秋季节。主要病原菌为大肠埃希菌、克雷伯菌和志贺菌,对常见抗生素较为敏感,但耐药呈逐年上升趋势。结论严格掌握抗生素的应用指征,用药前进行细菌分离鉴定和药敏试验,以保证临床合理用药。Objective To realize major pathogenic bacteria and their drug susceptivity in Guangzhou in order to provide relevant evidence for clinical diagnosis and therapy or epidemiological research.Methods To examine the stool of children by clinical bacteriology,who were hospitalized in Guangzhou Children＇s Hospital and suspected to catch bacterial infectious diarrhea.Results The infants were prone to catch infectious infantile diarrhea in summer and autumn.The major pathogenic bacteria were Escherichia coli,Klebsiella pneumoniae and shigella flexneri and their drug susceptivity was good for major antibiotics in despite of the decreased trend of their susceptivity year after year.Conclusion To master the application guide of antibiotics strictly and finish bacteria culture and identification and drug susceptivity test before a prescription for antibiotics in order to guarantee the reasonable clinical usage of antibiotics.
