Table 1 Virulence of bacterial strains used in this study. HV stands for highly virulent, V stands for virulent, WV stands for weakly virulent, and AV stands for avirulent. The virulence in pigs is described in [35] and the scale of virulence in pig infection model is as described in [35]. Strains leading to more than 50% mortality of G. mellonella larvae post-infection with 107 CFU/ml were considered virulent, and strains leading to less than 50% mortality of G. mellonella larvae were considered weakly virulent
