84株仔猪黄、白痢E.coli的体外药敏试验

从四川省不同规模化猪场临诊发生典型仔猪黄、白痢猪只的肛试粪样及死亡猪只的心血和肝脏中分离出致病性大肠杆菌８４株。用１２种常用抗菌药物对分离菌株进行了体外药敏测定，结果表明：大肠杆菌存在广泛的耐药性，以多重耐药性为主。庆大霉素、链霉素、痢特灵和喹诺酮类（环丙沙星、蒽诺沙星、诺氟沙星）等药物较为敏感。药敏试验结果为规模化猪场合理用药提供了科学依据

Drug Sensitive Test of 84 E.coli Strains of yellow and white Sour of Piglet

84 pathogenic E.coli strains were isolated from the typical cases of yellow and white sour of piglet in the different large-scale pig farm in Sichuan province.The isolates were performed drug sensitivity to 12 antibiotics.The results show that these E.coli strains have wide-ranging drug resistance and multi-resistance principally. GentamycinStreptomycinFurazolidonum and Fluoropuinolones EnrofloxacinCiprofloxacinNorfloxaclnare more sensitive than the others in this test.The results of drug sensitivity tests could offer the scientific reference to select drugs for large-scale pig farms on clinic.
