Strain/Species | Genetic Modification | Intestinal Microflora | Antibiotic Treatment | LOS Sensitized | Macroscopic Signs of Disease | Inflammatory Responses | Reference |
---|---|---|---|---|---|---|---|
BALB/c | Athymic (nu/nu) Euthymic (+/nu) | No, GF | No | Yes | Transient diarrhea | Cecal shrinkage, accumulation of eosinophils in the lower intestinal mucosa and lamina propria, translocation of viable C. jejuni to MLN, spleen, liver and kidneys | [59,60] |
C57BL/6 | IL-10−/− | SPF | No | Yes | Wasting, bloody diarrhea | Severe typhlocolitis and gross pathological changes in the gastrointestinal tract, increased immune cell responses and production of pro-inflammatory mediators | [56] |
129/SvEv | IL-10−/− | No, GF | No | Yes | Wasting, bloody diarrhea | Intestinal crypt abscesses and epithelial ulcerations. Increased mononuclear cells, neutrophils, and elevated pro-inflammatory mediators | [61] |
129/SvEv C57BL/6 | IL-10−/− | No, GF | No | Yes | Wasting, bloody diarrhea | Pronounced neutrophilic infiltration of the intestines; increased NF-κB activity and Il1β, Cxcl2, Il17a expression | [62,63] |
C57BL/10 | IL-10−/− | No, SA | Yes | Yes | Wasting, bloody diarrhea | Increases in apoptotic intestinal epithelial cells. Pronounced innate and adaptive immune cell responses, elevated intestinal pro-inflammatory mediators. Translocation of viable C. jejuni to MLN, extra-intestinal including systemic inflammation | [50,64] |
C57BL/6 | SIGIRR−/− | Modified | Yes | Yes | ND | Increases in intestinal granulocytes, goblet cell depletion, edema, elevated pro-inflammatory mediators, translocation of C. jejuni to subepithelial tissues | [54] |
ND, not determined; SA, secondary abiotic; SPF, specific-pathogen-free murine microbiota; GF, germfree; MLN, mesenteric lymph nodes.
