Research Abstract

Genomic DNAs of two S. suis virulent strains belonging two genetically different clones were subtracted by a genomic DNA of an avirulent strain. Twenty-three genes selected were found to exist in only virulent strains. These genes were knocked out via single-cross over, and one of the mutants showed remarkable loss of virulence. However, virulence of the knock out mutant via double-cross over was the same as its parent stain.
