  20. The research consist of four parts. the first part is multiplication, purification and electron microscope examination of the avian encephalomyelitis virus. a 1 : 5 dilution of isolate - nh937 of aev and control group of pbs were inoculated to susceptible 6 - day - old chickens embryos. respectively. after incubation for 10 days, the urinay vesicle liquid was collected. making a comparison the size of the chickens embryos between the test group and the control group, the results showed that the size of the control group is bigger than that of the test group. purified virions were examined under the electron microscope, the result revealed that there are a lot of virions and the aev - nh937 was multiplicated in embryos. the second part was seguence analysis of the genome of the aev - nh937. nine pairs of primers were designed according to published calnek vaccine strain of aev
