IL10 and campylobacteriosis: In order to investigate C. coli-induced campylobacteriosis and to determine the immunopathogenic role of C. coli LOS in the absence of any commensal gut microbiota, we here assessed the gastrointestinal colonization properties and the clinical, macroscopic, and microscopic inflammatory sequelae in intestinal and extra-intestinal compartments following peroral challenge of secondary abiotic TLR4-deficient IL-10−/− mice.
