ME virus
1.Objective To explore the gene changes of the mumps vaccine S79 strain during the successive 12 passages,and compare the sequence among the three viruses:S79 master seed virus(S79-1-3),S79 plaque-purified strain(S79-1-P7-3③)and ME (Enders) strain, a mumps virus strain cultivated in chicken embryonic allantoic fluid,in the laboratory.
3.MORPHOGENESIS OF THE VIRUS OF HEMORRHAGIC FEVER WITH RENAL SY NDRO-ME(HFRS) OBSERVED BY ELECTRON MICROSCOPY
