“…In spite of the predominance of small intestinal over colonic pathology in infected mice and the evident gross and microscopic lesions, the functional changes seem slight. Domingo and Warren (1966) did not find functional changes in the guts of infected mice while Vengesa and Lesse (1979) and Sadek et al (1986) noted changes in the absorption of glucose and fluid transport and of disaccharidase activity. Moreels et al (2001) found that at 12 but not 8 wk after infection that increased muscular con-tractility was present in the inflammed mouse gut and that transit through the GI tract was decreased.…”
