Abstract excerpt

Avirulent mutation of an opaque colony variant of Shigella flexneri 2a designated 24570 has been believed to be linked with the glpK locus of the chromosome. However, avirulent phenotypes of the 24570 strain could be complemented by the invasion plasmid-coded virF gene, a positive regulator for i...
