fulminant cryptosporidiosis associated with digestive adenocarcinoma in scid mice infected with cryptosporidium parvum tum1 strain.we recently demonstrated that cryptosporidium parvum iowa strain induces in situ ileo-caecal adenocarcinoma in an animal model. herein, the ability of another c. parvum strain to induce digestive neoplasia in dexamethasone-treated scid mice was explored. scid mice infected with c. parvum tum1 strain developed a fulminant cryptosporidiosis associated with intramucosal adenocarcinoma, which is considered an early histological sign of invasive cancer. both evidence of a role of c. parvum in adenoca ...201020708621
protection of calves against cryptosporiosis by oral inoculation with gamma-irradiated cryptosporidium parvum oocysts.the purpose of this study was to determine whether gamma-irradiated cryptosporidium parvum oocysts could elicit protective immunity against cryptosporidiosis in dairy calves. cryptosporidium parvum iowa strain oocysts (1 x 10(6) per inoculation) were exposed to various levels of gamma irradiation (350-500 gy) and inoculated into 1-day-old dairy calves. the calves were examined daily for clinical signs of cryptosporidiosis, and fecal samples were processed for the presence of c. parvum oocysts. a ...200415562625
