| Outline of Final Research Achievements |
Bacteria under hostile environmental conditions alter their gene expression to adapt and survive in the host. This study identified genes in Escherichia coli that acted for regulation of virulence in host with aid of the two-component regulatory system EnvZ-OmpR. Among sigma factors, we reported that RpoS, a type of RNA polymerase sigma factors in E. coli, induced expression of bacterial catalases for inhibition of phagocytic killing in host. In this study, we found that RpoS raised in host in a manner of post-transcriptional regulation for persistence in host.
