奶牛钩端螺旋体病防治

Prevention and Control of Leptospirosis in Dairy Cows

钩端螺旋体病是一种自然疫源性传染性疾病,是由多种血清型的致病性钩端螺旋体感染引发。奶牛感染钩端螺旋体后,临床上主要表现为体温显著升高,体表皮肤和黏膜出现不同程度的坏死,严重的流产,显著黄疸,血红蛋白尿。任何年龄任何品种的牛群对钩端螺旋体均具有易感性,年龄较小的牛群发病率相对较高。奶牛钩端螺旋体病具有传播速度快、传播范围广的特点,如果没有做好针对性的防控和有效的流行病学调查,极易造成疫情快速扩展蔓延,危及到整个牛群的身体健康。该文探讨奶牛钩端螺旋体病的流行特点、临床症状、病理特征、诊断方法和防治措施。

Leptospirosis is a naturally infectious infectious disease,caused by a variety of serotypes of pathogenic leptospira infections.The clinical manifestations of leptospira infection in dairy cows were marked increase of body temperature,necrosis of skin and mucous membrane,severe abortion,marked jaundice and hemoglobinuria.Cattle of any age and breed are susceptible to leptospira,and younger cattle have a higher incidence.The spread of leptospirosis in dairy cattle is fast and wide.If the prevention and control of the disease and the effective epidemiological investigation are not done well,the disease will spread quickly,endangering the health of the entire herd.This paper deals with the epidemiological characteristics,clinical symptoms,pathological features,diagnostic methods and control measures of leptospirosis in dairy cows.
