猪钩端螺旋体病流行与防治

The Prevalence and Prevention of Swine Leptospirosis

猪钩端螺旋体病是一种可通过消化道、皮肤黏膜接触和吸血昆虫传播的热性传染病,不同年龄段猪感染后因抗病力不同呈现不同的临床症状,对病猪的伤害程度也有差异,若防疫不当,母猪流产率和病猪死亡率均会增加。该文从科学选址和布局、切断病原传播途径、彻底清除病原、定期进行健康普查4个方面提出科学的预防管理。

Porcine Leptospirosis is a febrile infectious disease that can be transmitted through the digestive tract,skin and mucous membrane contact,and blood-sucking insects.Pigs of different ages are infected with different clinical symptoms due to different disease resistance.There are also differences in the degree of injury.If the epidemic is not properly prevented,the abortion rate of sows and the mortality of sick pigs will increase.Based on my own work experience,the author proposes scientific prevention and management from four aspects:scientific site selection and layout,cutting off the path of pathogen transmission,thorough removal of pathogens,and regular health surveys,for reference for peer exchanges.
