【摘要】 溶血性大肠杆菌O₁₃₉冻融裂解物离心上清液,通过交链葡聚糖凝胶层析,分离成三大组份。取第一组份,给猪作静脉注射,引起猪内毒素休克的临床症状和病理学变化;第二组份中的一部分给猪作静脉注射,引起猪产生类似于水肿病自然病例的临床症状和病理变化。试验猪大肠杆菌肠毒血症可分为两个类型:由内毒素引起的“内毒素休克型”和水肿病因子引起的“水肿型”（即水肿病）。更多还原

【Abstract】 Freeze-thawed lysates of hemolytic Escherichia coli O139 were centrifuged.The supernatant was separated into three portions by Dextran gel (sephadex G-200) chromatography. The first portion was parenterally administered to 7 weaned pigs. The clinical signs and pathology of the inoculated pigs were similar to those found in other endotoxin shocks. The second portion was parenterally administered to 8 weand pigs. Their clinical signs and pathological pictures were the same as those of the naturally occurring oedema disease of pigs. Experimental E.coli enterotoxaemia of swine can be divided into two categories: one is the "endotoxin shock type" produced by the endotoxin and the other "oedema type" caused by oedema diseasa principle.更多还原
