Effect of LC+mcra on reducing colonization of ST in mice gut intestine. The bacterial numbers of ST at 14, 21, and 28 days in cecum (a), jejunum (b), ileum (c), and feces (d) from ST-infected mice with no probiotic treatment, LC, or LC+mcra 1-week pretreatment were investigated in triplicate. Different letters (‘a’ through ‘c’) at individual time point (day 14, 21, or 28) are significantly different (p < 0.05) in the numbers of ST among control, LC pretreatment, and LC+mcra pretreatment.
