Advances in the Researches on Atypical Porcine Pestivirus
Atypical porcine pestivirus(APPV)is a new pestivirus virus firstly detected in 2015,which is determined as the representative strain of pestivirus K by the International Committee on the Taxonomy of Viruses in 2017. Because of the virus,congenital tremor(CT)might occur in piglets with such typical symptoms as slight tremor especially in head and limbs. APPV has been widely prevalent all over the world and also reported in China,but there are few reports related to the advances in relevant researches on the virus although with more reports about the researches. At present,it has been confirmed to be closely related to CT. It is difficult to isolate the virus due to the lack of most important results about virus attack test,and the development on vaccines could be achieved only based on the results of preliminary researches. Therefore,the latest relevant advances were summarized from the aspects of etiology,epidemiology,diagnostic technology and vaccine development,with a view to improving public's awareness for the virus and providing a reference for relevant prevention,control and researches in China.
