【摘要】 从不同地区养殖场的病死兔送检病料中分离出１４株大肠埃希氏杆菌，均对小白鼠有强的致病性，对其培养的菌落形态特征、生化特性、致病性、抗生素药物敏感性进行了细菌生物学特性研究，血清型有待以后测定。更多还原

【Abstract】 strains of Escherichia coli were isolated from sick rabbits of different farming areas .All the 14 strains have high pathogenicity for the white mice. We studied the E.coli isolates on the characterization of colony culture,pathogenicity and antibiotics sensitivity.Serogroups could not be serotyped.更多还原
