Fig. 7From: Iron-regulated gene ireA in avian pathogenic Escherichia coli participates in adhesion and stress-resistanceResistance to alkaline and high osmolarity. The resistance to alkali (a) and high osmolarity (b) of wild-type strain DE205B, mutant strain DE205BΔireA and complementary strain DE205BCΔireA was tested by exposing the strains to alkaline and high osmolarity conditions and calculating their survival rates. Compared with the wild-type strain, the survival rate of the ireA deletion mutant was reduced 21.17 % (P < 0.01) and 25.42 (P < 0.05) under alkaline and high osmolarity conditions, respectivelyBack to article page
