Fig. 6From: Iron-regulated gene ireA in avian pathogenic Escherichia coli participates in adhesion and stress-resistanceAdherence assays. The adhesion abilities of the wild-type strain DE205B, mutant strain DE205BΔireA and complementary strain DE205BCΔireA to DF-1 cells were tested. The numbers of adherent cells were calculated by plate counting. The number of DE205BΔireA mutant bacteria adhering to DF-1 cells was significant decreased compared with the number of DE205B wild-type bacteria (P < 0.05)Back to article page
