Bar Plot from Scientific Research

Growth competition between E. coli mcr-1 + and E. coli mcr-1 - in the presence of E. coli C600 strains producing colicin A, D, E1, or E2. After 16 h of coculture in LB medium, serial dilutions were spread on blood sheep agar plates, and E. coli mcr-1 + and E. coli mcr-1 - colonies were counted. Data are expressed as the number of colony-forming units (CFUs). Data are means SEMs of four replicates and are representative of three independent experiments.
