Coli XL-1 strain, purposed cassette recombination plasmids pNB0098-K and pNB0097-K were constructed, in which the purposed gene was linked with plasmid pUC18, and the marker gene kanamycin was inserted in the purposed gene. The linear cassette DNA fragment was mixed in the medium of cultured competent cells of meningococcus BT878. The function of the purposed gene was inhibited by the homologous replace of casstte gene.
