Efficacy of Lactobacillus reuteri as a probiotic for the control of Cryptosporidium parvum infection was evaluated in C57BL/6 female mice that were immunosuppressed by intraperitoneal inoculation with the LP-BM5 leukemia virus. Four months after inoculation, mice developed lymphadenopathy, splenomegaly, and susceptibility to C. parvum infection. After daily prefeeding with L. reuteri (108 cfu/day) for 10 days, mice were challenged with 6.5 × 106 C. parvum oocysts and fed L. reuteri during the entire study. Mice supplemented with L. reuteri and challenged with C. parvum cleared parasite loads from the gut epithelium. However, unsupplemented animals developed persistent cryptosporidiosis and shed high levels of oocysts in the feces. L. reuteri feeding increased its colonization of the intestinal tract, which was inversely related to the fecal shedding of oocysts. These findings suggest that L. reuteri may help prevent C. parvum infection in immunodeficient subjects. [ABSTRACT FROM PUBLISHER] |
