鸭大肠杆菌病是由大肠埃希氏菌引起的一种急性败血性传染病,发病急,死亡快,主要侵害2~6周龄的雏鸭,特征性病变为心包炎、肝周炎、气囊炎等[1]。鸭大肠杆菌病常因单一或者混合性感染给养禽业造成严重的经济损失,临床上常用各种抗菌药物进行防治,但对抗菌药物过分的依赖造成了耐药菌株的不断产生与进化,且可通过食物链传递给周围环境以及人类,会导致抗菌药物对人类疾病治疗效果的下降甚至无效。本试验应用临床分离的对四环素高度
Duck E. coli disease is an acute sepsis caused by Escherichia coli, the incidence of acute and rapid death, mainly for 2 to 6 weeks old ducklings, the characteristic lesions of pericarditis, perihepatitis, air bags Inflammation [1]. Duck E. coli disease often caused by a single or mixed infection caused serious economic losses to the poultry industry, commonly used in clinical prevention and treatment of various antimicrobial agents, but excessive dependence on antibiotics caused resistant strains continue to produce and evolve, and Through the food chain to the environment as well as humans, will lead to antibiotic treatment of human diseases, the decline or even null and void. This test applies clinically isolated tetracycline-highly
