DnaK supports intracellular persistence of Staphylococcus xylosus and confers mechanical resilience to a human breast cancer cell line
Fig 3
DnaK is dispensable for resistance to hypoxic stress and antimicrobial peptide exposure.
(A) Growth of wild-type, ∆dnaK, and ∆dnaK-C strains under hypoxic conditions (1% O₂). OD₆₀₀ measurements and CFU enumeration were performed at indicated time points. (B) Survival of strains following treatment with LL-37 (10 µg/mL, 2 h). Viable CFUs were determined by plating. Data represent means ± SEM from three independent experiments. Differences among groups were analyzed by one-way ANOVA. p < 0.05; ns, not significant.
