鸡大肠杆菌病的流行病学研究

Studies on Epidemiology of the Chicken Colibacillosis

摘要: 对来源于河南省32个县市的93株鸡致病性大肠杆菌进行了O血清型的鉴定、16种抗生素药物的耐药性试验和耐药性质粒的检测分析.结果表明:河南省鸡致病性大肠杆菌的血清型种类众多,以O78、O1、O2为优势血清型,分别占定型菌株的35.14%、18.92%、13.51%;耐药图谱复杂,可以分为58种耐药类型,菌株耐药种类3~14种;质粒图谱复杂,可分为49种质粒图谱,质粒条带1~6条.

Abstract: 93 stains of chicken's pathogenic E.coli were isolated from chicken farms of 32 districts and cities in Henan province and studied in three aspects: O serotype identification,drug-resistance to 16 antibiotics,and plasmid DNA pattern.The results show that the predominant serotypes are O78(35.14 %),O1(18.92%),O2(13.51%) and all isolates are multi-resistance.The antibiotic resistance species vary from 3 to 14.Among the drug-resistance pattern of the 93 strains,58 kinds of pattern could be determined,and the 93...
