A Strains were seeded at low optical density and grown in BHI at 37 °C for 24 h and then stained with crystal violet (representative image). B Quantification of crystal violet staining for WT and deletions mutants of lacA (ΔlacA), galK (ΔgalK), and both (ΔgalK/lacA). Vertical lines show SEM. C Growth curve of WT and mutant strains in BHI at 37 °C. The mean of at least three biological replicates with their SEM is given. Statistical analysis was performed using One-way ANOVA followed by Tukey’s multiple comparisons test (**p = 0.0047). Source data are provided as a Source Data file.
