Growth behavior of strains over-producing BASI74 under different stress conditions. (A) Over-expression of BASI74 did not affect the survival ratio of B. abortus in acidic medium (TSB pH 4.5). (B) The 2308-BASI74 strain had equal sensitivity to 30% H2O2 compared to two control strains. (C) BASI74 affected bacteria growth in Brucella minimum medium. (D) Over-expression of BASI74 reduced the survival ratio of B. abortus under iron-limiting condition. Values represent the means of three independent experiments, and error bars indicate the SD. indicated the p < 0.05. ∗∗ indicated the p < 0.01.
