FIG. 2.

Dependence of intestinal hypermotility on intact T- and B-cell functions. Adult C57BL/6 (wild-type [WT]) and SCID mice were infected orally with G. muris cysts or left uninfected as controls, and small-intestinal motility (A) and trophozoite numbers (B) were evaluated 2 weeks after infection. Values are mean ± SEM for four to six animals. The asterisk designates a significant increase (P < 0.05, t test) relative to uninfected controls.
