Fig. 1.

Comparison of the OMVs production.The concentration of OMVs, isolated from C. jejuni 81–176 grown under optimal and stress conditions (15% O2 and polymyxin B) and from C. jejuni 81–176 dsbI and htrA mutants, was measured by BCA assay. The concentration of OMVs produced by the strain grown under optimal conditions was marked as 1. A statistical analysis was performed using GraphPad Prism 6 (GraphPad Software). Statistical analysis was carried out using multifactorial (one-way) ANOVA followed by Tukey’s multiple comparisons test. An asterisk indicates significant differences (p < 0.05) between analyzed groups and the control group.
