Abstract:
Surra is a bloodborne protozoan disease caused by Trypanosoma evansi(T.evansi)that infects most mammals and is widely distributed worldwide.The Ministry of Agriculture of China classifies Surra as a category Ⅲ animal disease,it can lead to anemia,wasting,and even death in e-quine animals,camels,buffaloes,etc.,causing huge economic losses to the stock raising industry.In addition,T.evansi may also have zoonotic potential,making its accurate diagnosis crucial.Howev-er,the close affinity between the subgenus of trypanosomes,as well as the presence of antigenic variation and immune escape,make the accurate diagnosis of T.evansi difficult.In this paper,we review the pathogens,immune mechanism,diagnosis,prevention and control of Surra,aiming to provide scientific references for the accurate diagnosis and prevention of this disease.
