Abstract: | One-week-old-germ-free pigs were inoculated with 10(8) CFU of E.coli bacteria-either commensal 086 strain or virulent 055 strain for 1 d. Bacteria were counted in the small intestine, mesenteric lymph nodes, blood and lungs. The O55 strain reached higher levels in circulation and lungs. IL-8, IL-10 and TNF-alpha concentrations were determined by ELISA in plasma and intestinal washes . No difference in cytokine levels was found between control germ-free pigs and their counterparts associated with commensal O86 strain in spite of its high concentration in the gut and circulation. |
