Colonic C. showae strains demonstrate a range of virulence potential. (A) Adhesion to HT29 colonic epithelial cells with SEM. For images within inset: B32_SW- (top) and CAM-infected (bottom) cells. (B) and (C) Galleria mellonella killing. Groups of 10 larvae were used and the results shown are the means of three experiments recorded 24 h after challenge. Error bars indicate standard errors of the mean. *P < 0.05 (survival compared with C. jejuni; Welch-corrected 2-tailed t tests for pooled data from three separate experiments). (D) Evidence of biofilm formation in isolate B91_SC. Results shown are the means of three independent experiments recorded 24 h after inoculation. Error bars indicate standard errors of the mean. (E) Cytokine production from THP1-cells. Error bars indicate standard errors of the mean.
