鸡新城疫与大肠杆菌病混合感染的诊治

鸡新城疫是由鸡新城疫病毒引起的一种急性、高度接触性传染病,致死率较高。目前,我国普遍采用以新城疫疫苗接种为主的综合防控措施,能够在很大程度上控制该病的大规模流行。鸡大肠杆菌病是由大肠埃希菌感染引起的传染病,多个血清型的大肠埃希菌是多种动物肠道内的常驻菌,因此其分布极为广泛,致病率也较高,并且多与其他疫病混合感染。通过开展病死鸡的病理变化检查、实验室检验以及分离菌株的药物敏感性试验,对临床接诊的鸡新城疫及大肠杆菌混合感染病例进行诊断并提出综合防控措施,以期为兽医临床2种疾病的防控提供有益参考。

Diagnosis and Treatment of Mixed Infection of Colibacillosis and Newcastle Disease

Newcastle disease of chicken, caused by newcastle disease virus, is a kind of acute and highly-contagious infectious disease with higher lethallty rate. Nowadays, comprehensive prevention and control measures with vaccine inoculation as main measures are commonly used in China, which could control large-scale prevalence of Newcastle disease to a great extent. Chicken colibacillosis is a kind of infectious disease that caused by Escherichia coli. Various kinds of E. coli are main bacteria in the intestines of many kinds of animals and their distribution is extremely broad. And its pathogenic rate was higher, and E. coli is often mixed with the infection of other diseases. The mixed infection cases of Newcastle disease of chicken and colibacillosis were diagnosed by pathological examination of dead chicken, laboratory examination and drug sensitivity test on the isolated strains. And some comprehensive prevention and control measures were proposed so as to provide useful references for preventing and controlling colibacillosis and newcastle disease.
