Abstract
According to the present invention, immortalized cells derived from porcine kidney macrophages are found to have high infection susceptibility to various African swlne fever virus strains. As a result, using the cells, it is possible to proliferate the virus and furthermore produce and detect the virus.
Claims10
A method for producing African swine fever virus comprising the step of bringing an immortalized porcine kidney macrophage into contact with African swine fever virus to proliferate the virus in the immortalized porcine kidney macrophage.
A method for producing a vaccine containing African swine fever virus, comprising the steps of:
- bringing an immortalized porcine kidney macrophage into contact with African swine fever virus to proliferate the virus in the immortalized porcine kidney macrophage;
- isolating the African swine fever virus proliferated;
- and
- mixing the isolated African swine fever virus with a pharmacologically acceptable carrier or medium.
An immortalized porcine kidney macrophage infected with African swine fever virus.
An immortalized porcine kidney macrophage which is obtained by introducing lentivirus encoding SV40 large T antigen and porcine-derived telomerase reverse transcriptase into a porcine-derived kidney macrophage, and which is infected with African swine fever virus.
An immortalized porcine kidney macrophage comprising DNA in which a reporter gene is functionally bound to a position downstream of a promoter region of an African swine fever virus-derived gene.
An immortalized porcine kidney macrophage which is obtained by introducing lentivirus encoding SV40 large T antigen and porcine-derived telomerase reverse transcriptase into a porcine-derived kidney macrophage, and which comprises DNA in which a reporter gene is functionally bound to a position downstream of a promoter region of an African swine fever virus-derived gene.
