Biofilm formation ability. Biofilm formation ability of strains from different sources, as well as that of their corresponding transconjugants. (A) DH5α control. Strains used in the biofilm formation assay were isolated from (B) the environment, (C) chickens, (D) meat, (E) flies, (F) humans, (G) swine, and (H) companion animals. (I) The percentages of strains showing no change, enhanced, and impaired biofilm formation following acquisition of the p3R-IncX3 plasmid. *, p < 0.05; **, p < 0.01, ns means no differences.
