鸡大肠杆菌病与慢性呼吸道病混感诊治

Diagnosis and Treatment of Chicken Colibacillosis and Chronic Respiratory Diseases

大肠杆菌病是家禽养殖领域发生流行率很高的一类细菌性传染性疾病,通常是由致病性大肠杆菌感染引发。养殖场养殖密度大,圈舍通风不良,卫生消毒不合理,养殖管理不科学,经常会造成大肠杆菌病的发生流行。发病后,由于鸡出现严重的腹泻和生长发育不良,身体抵抗力显著下降,极容易引发各类细菌、病毒、支原体的混合感染。慢性呼吸道疾病是由败血霉形体感染引发的一种慢性传染性疾病,该种疾病发病进程较为缓慢,死亡率相对较低,但发病周期长,会对鸡的生长发育造成不良影响。上述两种疾病混合感染,临床症状会进一步加重,死亡率显著升高,带来不必要的经济损失。该文探讨了鸡大肠杆菌病和慢性呼吸道疾病混合感染的诊断与防治。

Escherichia coli is a type of bacterial infectious disease with a high prevalence in poultry farming.It is usually caused by pathogenic Escherichia coli infection.The relatively high breeding density of breeding farms,poor ventilation of the pens,unreasonable sanitation and disinfection,and unscientific breeding management often lead to the spread of colibacillosis.After the emergence of colibacillosis,due to severe diarrhea symptoms and poor growth and development of the chickens,the body's resistance ability will be significantly reduced,and it is very easy to cause various bacterial diseases,viral diseases,and mixed infections of mycoplasma.Chronic respiratory disease is a chronic infectious disease caused by Mycoplasma septicum infection.This disease progresses slowly and causes relatively low mortality,but the disease cycle is relatively long,which will cause the growth and development of chickens.Adverse effects.After the mixed infection of the above two diseases,the clinical symptoms are further aggravated,the mortality rate is significantly increased,and unnecessary economic losses are caused.Based on actual work experience,this article discusses the diagnosis and prevention of mixed infections of chicken colibacillosis and chronic respiratory diseases.
