Table 1 Adhesion and invasion of S. Dublin (SDu) and S. Typhimurium (STm) WT and flagella and chemotaxis mutants a in cultured epithelial Int407 cells

From: The role of flagella and chemotaxis genes in host pathogen interaction of the host adapted Salmonella enterica serovar Dublin compared to the broad host range serovar S.Typhimurium

  1. a: Performance of mutant strains was compared statistically to the wild type strain of the same serovar. **: p<0.01; ***: p<0.001.
  2. The inoculum of each strain was between Log10 7.9 and Log10 8.2 with no significant difference between strains.
