Advance in Molecular Biology of Peste Des Petits Ruminants Virus

Peste des petits ruminants virus(PPRV) is the etiological agent of peste des petits ruminants(PPR),which is an acute and highly contagious viral disease,mainly infectes goats,sheep,antelope and other small ruminants,is especially susceptible to goats.Cattle,pigs,etc.can also be infected with the virus,but usually appearing subclinical effect,wildlife happen once in a while.This article described the advance in the structure features of PPRV genes,the functions of the six structural protein,expressing protein in vitro and the molecular biological diagnostic techniques.
