Cryptosporidium spp. is an obligate intracellular parasite that has become a community threat. The pathological consequences of cryptosporidiosis vary not only in different Cryptosporidium species but even among different isolates of the same species. The present study aimed to track the serological and immunohistopathological differences between animals infected by Cryptosporidium parvum "Iowa isolate" (CPI) and Cryptosporidium parvum "water isolate" isolated from a local water supply in Assiut Governorate, Egypt (CPW). Three experimental groups were encountered: negative control group (C), the CPI group and the CPW group; each contains ten Swiss albino mice. Serum cytokine: IL10 and TNF-α were measured. Expression of Cryptosporidium antigen and CD3 in the intestinal, pulmonary and brain tissue were evaluated through immunohistochemical assay. IL10 and TNF-α were elevated in both infected groups, over expression of Cryptosporidium protein and CD3 in the intestinal, pulmonary and brain tissue in CPW infected group compared to Iowa infected one. Multi-organs affection occurred in the CPW indicating more severe pathogenicity and virulence than standard Iowa isolate. The local C. parvum isolate was more virulent than tested Iowa isolate as it spread extra-intestinally to reach brain tissue. |
