Open the CIPO recordAbstract From the Canadian patent
By studying how the deletion of 11 bases from swine Mx1 gene affects the capability of inhibiting the proliferation of influenza virus which is one of myxoviruses, it is revealed that the mutant with the deletion of the 11 bases completely loses the capability of inhibiting the proliferation of the virus. Therefore, the resistance to an RNA virus such as influenza virus or PRRS virus can be judged by detecting the deletion of these 11 bases in swine.
