致羔羊腹泻主要寄生虫病原的研究进展

Research Progress on Main Parasitic Pathogens Causing Lamb Diarrhea

羔羊腹泻是羊的一种常见病和多发病,主要特征为腹泻、下痢,导致羔羊生长缓慢甚至死亡。引起羔羊腹泻的因素较为复杂,除饲养管理因素外,寄生虫感染是致羔羊腹泻的重要因素。腹泻相关病原的共同感染较常见,对放牧羊腹泻的实地调查提出了挑战。该文对致羔羊腹泻的常见寄生虫病原进行综述,旨在为今后羔羊腹泻疾病的监测、免疫计划的制定和疾病防控提供参考。

Lamb diarrhea is a common and frequently occurring disease in sheep,mainly characterized by diarrhea and dysentery,which leads to slow growth and even death of lambs.The factors causing diarrhea of lambs are relatively complex.Apart from feeding and management factors,pathogenic infection is an important factor causing diarrhea of lambs.Co-infection of diarrhea-associated infectious agents is common and poses a challenge to field investigation of diarrheal sheep.In this paper,the common parasitic pathogens causing lamb diarrhea were reviewed,aiming to provide reference for the surveillance of lamb diarrheal disease,the formulation of immunization plan and the prevention and control of the disease in the future.
