鸡大肠杆菌病发病原因与防治

Causes and Prevention of Chicken Colibacillosis

大肠杆菌病是家禽养殖产业很容易发生的一类病害,具有发病突然、传播速度快、致死率高的特点。不同年龄、不同品种的鸡都可以受到大肠杆菌的侵染,其中幼龄鸡感染大肠杆菌后表现的症状最为严重,造成的死亡率最高。大肠杆菌属于条件性致病菌,该种疾病在养殖场中发生流行,通常是各种致病条件共同制约造成,鸡群身体抵抗能力下降给病原侵染流行提供条件。在疾病防治过程中,应不断加强发病原因总结,对养殖管理方案做出动态化调整,保证疾病防控针对性,降低发病率。该文主要探讨鸡大肠杆菌病的诊断和防治过程。

Escherichia coli disease is a type of disease that is prone to occur in the poultry breeding industry.It has the characteristics of sudden onset,fast transmission,and high fatality rate.Chickens of different ages and breeds can be infected by e.coli.Among them,young chickens are infected with e.coli and exhibit the most severe symptoms and cause the highest mortality.Escherichia coli is a conditional pathogen.This kind of disease is prevalent in farms.It is usually caused by various pathogenic conditions.The decline in the body's resistance of chickens provides conditions for pathogen infection and epidemic.In the process of disease prevention and control,it is necessary to continuously strengthen the summary of the causes of disease,make dynamic adjustments to the breeding management plan,ensure the pertinence of disease prevention and control,and reduce the incidence rate.This article mainly discusses the diagnosis and prevention process of chicken colibacillosis.
