6.By making experimental research with 318 positive serums of animal, this paper first reports the results of inhibit appearence in the preceeding test tubes, the inhibition rate and the dilute scope for inhibition in the detection of plague F1 antibody with Radioimmuno precipitation (RIP) test.
9.The polymerase chain reaction(PCR) technique was used to determine virulent duck plague virus(DRV) in 100-dayold ducks infected artificially with DPV and infected naturally with DPV,and observe the histopathology changes of tissues and organs.
