摘要
鹅大肠杆菌病是由致病性大肠杆菌侵染引发的一种细菌性传染性疾病,该种疾病主要危害2周龄的雏鹅,大多患病鹅呈现急性败血症情况,具有很高的发病率和致死率。患病鹅隐性带菌鹅是养殖场的主要传染源。大肠杆菌的侵染途径多种多样,既可通过直接接触传播,也可通过污染周围环境、空气尘埃和种蛋进行传播。大肠杆菌病发生流行不受季节影响,一年四季均可发生,其中以潮湿、多雨、闷热的夏秋季节发病率最高。近年,随着鹅养殖密度的不断增加,大肠杆菌病还易和其他细菌性疾病,病毒性疾病混合感染,表现出复杂的临床症状,发病过程更短,致死率更高,给养殖业造成的经济损失更大。该文主要论述鹅大肠杆菌病的诊断和防治。
Colibacillosis in geese is a bacterial infectious disease caused by pathogenic E.Coli,which mainly affects goslings at 2 weeks of age.Most sick goslings present with acute septicemia,with a high morbidity and mortality rate.The recessive carrier goose of infected goose is the main source of infection in the farm E.Coli can be transmitted by direct contact or through contamination of the environment,airborne dust and eggs.The prevalence of colibacillosis is not affected by seasons,and it can occur in all seasons of the year,especially in humid,rainy and muggy summer and autumn.In recent years,with the increasing of goose breeding density,E.coli disease is easy to be mixed with other bacterial diseases and viral disease infection,showing complicated clinical symptoms,shorter course of onset and higher mortality rate,the economic loss to the farming industry is even greater.This paper mainly discusses the diagnosis and control of colibacillosis in geese.
