The effect of L. acidophilus supplementation to reduce fecal shedding of Cryptosporidium parvum oocysts was compared to L. reuteri using C57BL/6 female mice immunosuppressed by murine leukemia virus (strain LP-BM5) inoculation.

The LP-BM5 murine leukemia virus causes acquired immunodeficiency syndrome in C57BL/6J mice (MAIDS), similar to that of AIDS in humans. The objective of this study was to determine the effect of LP-BM5 viral infection on cellular activation and membrane integrity of splenocytes. Oxidative burst in splenocytes in response to exposure to PMA (20 microg/ml) was significantly higher (p<.

Four months after inoculation, mice developed lymphadenopathy, splenomegaly, and susceptibility to C. parvum infection.

The intestinal mucosae of retrovirally immunosuppressed animals were heavily colonized by Cryptosporidium parasites, and oocysts shedding in the feces persisted throughout the duration of the study. Mortality was exacerbated by murine retrovirus infection alone and exacerbated with concomitant chronic alcohol feeding (42.

Mice were infected with LP-BM5 murine leukemia retrovirus for four months and then inoculated with Cryptosporidium parvum oocysts. Persistent cryptosporidiosis was established in all retrovirus immunosuppressed mice, while control mice were refractory to infection.
