flgL mutation reduces pathogenicity of Aeromonas hydrophila by negatively regulating swimming ability, biofilm forming ability, adherence and virulence gene expression.

Abstract excerpt

Aeromonas hydrophila is a serious human and animal co-pathogenic bacterium. Flagellum, a key virulence factor, is vital for bacterium tissue colonization and invasion. flgL is a crucial gene involved in the composition of flagellum. However, the impact of flgL on virulence is not yet clear. In this study, we constructed a stable mutant strain (△flgL-AH) using homologous recombination. The results of the attack...
