PdcABC signaling cascade contributes to the virulence of B. thailandensis. (A) Virulence survival of relative B. thailandensis strains in G. mellonella larvae. Ordinate represents the mean percent survival rate of G. mellonella infected with different strains after 16 h. (B) Western blot detection of BipD secretion in relative B. thailandensis strains. Proteins in the culture supernatant of relevant B. thailandensis strains were probed for specific anti-BipD rabbit polyclonal antibody. For the pellet fraction, isocitrate dehydrogenase (ICDH) was used as a loading control. (C) The expression of bipD in relative B. thailandensis strains. Data shown are the averages and SD from three independent experiments. *, P < 0.05; **, P < 0.01; ***, P < 0.001.
