Bactericidal activity of CsAg02 against susceptible and resistant Gram-negative pathogens: (A) E. coli ATCC 25922, (B) ESBL E. coli ATCC 51446, (C) Salmonella enterica serovar Typhimurium ATCC 14028, and (D) P. aeruginosa ATCC 27853. The reported values represent the average and standard deviation of at least three independent experiments. Statistical significance (paired t test) of Cs-inoculated 24 h bacterial growth compared to standard 24 h bacterial growth: ***, P = 0.0006; **, P = 0.007.
