Effect of the polysaccharide capsule and its heptose on the resistance of Campylobacter jejuni to innate immune defenses.

Campylobacter jejuni is a commensal in many animals but causes diarrhea in humans. Its polysaccharide capsule contributes to host colonization and virulence in a strain- and model-specific manner. We investigated if the capsule and its heptose are important for interactions of strain NCTC 11168 with various hosts and their innate immune defenses.

In Vitro Framework to Assess the Anti- Potential of Lactic Acid Bacteria Secretions as Alternatives to Antibiotics.

is a prevalent bacterium that can cause gastric ulcers and cancers. Lactic acid bacteria (LAB) ameliorate treatment outcomes against suggesting that they could be a source of bioactive molecules usable as alternatives to current antibiotics for which resistance is mounting. We developed an in vitro framework to compare the anti- properties of 25 LAB and their secretions against .
