【摘要】 以试管两倍稀释法测定硫酸新霉素对鸡大肠杆菌的最小抑菌浓度，然后对人工诱发大肠杆菌病雏鸡进行肌肉注射给药3天的治疗试验。结果表明，硫酸新霉素对鸡大肠杆菌的最小抑菌浓度为1．75mg／L；硫酸新霉素高剂量组、中剂量组、低剂量组对鸡大肠杆菌病的治愈率分别是13．3％、50％、86．7％，而感染对照组的死亡率为83．3％。硫酸新霉素低剂量肌肉注射对鸡大肠杆菌病有较好的治疗作用。更多还原

【Abstract】 In this study，the minimum bacteriostasis concetration of Neomycini Sulfas was determined by Tube Diplodllution Test and then therapeutie trial was camed out on chicken which were infected experimentalE．coil by injeeting in muscle with Neomycini Sulfas for 3 days．The result indlcated that Neomycini Sidfas minimum bacteriostasis concentration to E．coil is 1．75mg／l．The cure rate of megadose， mediatedose and mierodose groug with Neomycini sulfas were 133％,50％and 86.7％ respectively．While the doath rate of control group was 83．3％and the therapeutie offect of Neomycini Sulfas of microdose on chicken colibacillosis was the best by injeeting in muscle．更多还原
