| 摘 要： | 为了解大肠杆菌的致病机理及为防治提供科学指导,用从规模养猪场的空气、污水、粪便和土壤样本中分离鉴定的大肠杆菌腹腔注射小白鼠,通过临床症状观察和病理学检查研究其致病性.结果表明,小白鼠出现精神萎靡、拉稀、眼帘粘连、消瘦、被毛蓬乱等临床症状,小白鼠致死率达51.3%,其中污水源和空气源样本菌株对小白鼠的致死率最高,均为66...

| Abstract: | The clinical symptoms and pathology of white mice injected with E.coli strains isolated from air,sewage,excrement and soil of a scale pig farm were observed to study the pathopoiesis mechanism of E.coli and to provide the scientific basis for its control.The clinical symptoms of the mice injected with E.coli strains are listlessness,diarrhoea,eyeadhesion,emaciation and hair dishevelment,the fatality rate of the mice injected with E.coli strains reaches 51.3% and the fatality rate of the mice injected with E... |
