Fig. 4.
Intestinal contractility of C57BL/6 (immunocompetent and immunosuppressed) and ICR mice as measured by charcoal meal gastrointestinal-transit test. Statistically significant differences (P<0.05) compared with uninfected mice are illustrated as an asterisk (*). In immunocompetent C57BL/6 mice, the ratio of charcoal meal transit at day 3 (**) and day 5 (**) were significantly higher (P<0.05) than the ratio of uninfected C57BL/6 mice (day 0).
