摘要
从豫南大型鸡场出现典型病变的病死鸡中分离到26株大肠杆菌(Escherichia coli),对其进行培养特性、形态特性、生化试验和血清型鉴定,其分别属于O1、O2、O45、O86、O138血清型.根据中兽医学理论和中医药在现代医学上的应用成果,以石膏、滑石、白头翁、苍术等组方制成中兽药散剂,经过药敏试验、对比治疗试验及区域性治疗试验表明,所分离的5株大肠杆菌对中兽药散剂最敏感(100%,)其次是庆大霉素、丁胺卡那、恩诺沙星、诺氟沙星等,中兽药散剂对鸡大肠杆菌病最高治愈率达91%.
26 strains of Escherichia coli were isolated from diseased chicken with typical pathological changes on a farm in south of Henan Province.They were identified by cultural characters,morphological characters,biochemical tests and serological tests.The results showed that they belonged to O1,O2,O45,O86 and O138,respectively.The traditional veterinary drug preparation was made of plaster,talcum,Chinese pulsatilla root,atractylodes,et al.Susceptibility tests and therapeutic tests indicated that the isolated escherichia coli had the most sensitivity to traditional veterinary drug preparation,up to 100%,and had next sensitivity to gentamycin,amikacin,Enrofloxacin and norfloxacin.The traditional veterinary drug preparation had the highest cure rate for chicken with colibacillosis,up to 91%.
