Campylobacter jejuni is a leading cause of bacterial food poisoning in humans.
Due to the rise in antibiotic-resistant Campylobacter, there exists a need to
develop antibiotic-independent interventions to control infections in humans.
Here, we evaluated the impact of Escherichia coli Nissle 1917 (EcN), a probiotic
strain, on C. jejuni's invasion and intracellular survival in polarized human
colonic cells (HT-29). To further understand how EcN mediates its impact, the
expression of 84 genes associated with tight junctions and cell adhesion was
profiled in HT-29 cells after treatment with EcN and challenge with C. jejuni.
The pre-treatment of polarized HT-29 cells with EcN for 4 h showed a significant
effect on C. jejuni's invasion (?2 log reduction) of the colonic cells.
Furthermore, no intracellular C. jejuni were recovered from EcN pre-treated HT-29
cells at 24 h post-infection. Other probiotic strains tested had no significant
impact on C. jejuni invasion and intracellular survival. C. jejuni decreased the
expression of genes associated with epithelial cells permeability and barrier
function in untreated HT-29 cells. However, EcN positively affected the
expression of genes that are involved in enhanced intestinal barrier function,
decreased cell permeability, and increased tight junction integrity. The results
suggest that EcN impedes C. jejuni invasion and subsequent intracellular survival
by affecting HT-29 cells barrier function and tight junction integrity. We
conclude that EcN might be a viable alternative for controlling C. jejuni
infections.
