【Abstract】 Applying HA gene of and NA gene influenza virus to immunize BALB/c mice,the apparent specific reaction was observed.The titer of antibody was shown a positive correlation with the amount of applied genes.The livability of immunized mice were 100%,after challenging with the same type of influenza virus in each tested group.The livability of HA gene immunized mice were 100%,challenging with hetero type of the virus.The livability of NA gene immunized mice were 75%,challenging with hetero type of the virus.The mice were attacked by hetero type of the virus,which were immunized by the combination of HA gene and NA gene,their livability were 100%.更多还原
