Effect of Yogurt and Bifidobacterium on Cryptosporidium parvum Infection In Experiential Infected Mice

Abstract

        This study aimed to collected 150 feces sample from calves suffering sever diarrhea ,then there were isolation and purification of Cryptosporidium parvum oocyst from samples contain it. These oocysts were used to induce experimental infection in the Immunosupperessed mice, then the mice treated by Bifidium bacteria , its supernatant and local yogurt were used for bacterial isolation.

       This study showed that the local yogurt was the best treatment which led to stop oocyst shedding from the mice in the 8^th day after treatment under sufficient treatment (89.72%) , at the same time the mice treated with bacteria stopped the oocyst shedding in the 9^th day with sufficient treatment (81.40 %) , while its supernatant were stopped the oocysts shedding in the 10^th day with sufficient treatment (43.4%).
