Pathogenesis of human and bovine Cryptosporidium parvum in gnotobiotic pigs.
To compare the pathogenesis of human genotype 1 (HuG1) and bovine genotype 2 (BoG2) Cryptosporidium parvum, neonatal gnotobiotic pigs were given 1-10 HuG1 or BoG2 oocysts. The prepatent and patent periods were significantly longer for HuG1 than for BoG2 C. parvum (prepatent, 8.6 vs. 5.6 days; patent, 16.6 vs. 10.3 days). BoG2-infected pigs developed significantly more severe disease than did Hu...
متن کاملEfficacy of nitazoxanide, tizoxanide and tizoxanide glucuronide against Cryptosporidium parvum development in sporozoite-infected HCT-8 enterocytic cells.
The effects of nitazoxanide and its metabolites, tizoxanide and tizoxanide glucuronide, on the development of the asexual and sexual stages of Cryptosporidium parvum in differentiated human enterocytic HCT-8 cells were evaluated in a quantitative alkaline phosphatase immunoassay. Nitazoxanide, tizoxanide and tizoxanide glucuronide were inhibitory for up to 46 h when added after sporozoite invas...
متن کاملDifferentiating human from animal isolates of Cryptosporidium parvum.
We analyzed 92 Cryptosporidium parvum isolates from humans and animals by a polymerase chain reaction/restriction fragment length polymorphism method based on the thrombospondin-related anonymous protein 2 gene sequence. Used as a molecular marker, this method can differentiate between the two genotypes of C. parvum and elucidate the transmission of infection to humans.
متن کاملCryptosporidium parvum and Cryptosporidium andersoni infection in naturally infected cattle of northwest Iran
The protozoan intestinal parasite Cryptosporidium commonly infects cattle throughout the world and Iran. The present study was undertaken to determine the abundance and associated risk factors of Cryptosporidium infection in cattle herds of northwestern Iran. A total number of 246 fecal samples from 138 (56.1%) diarrheic (D) and 108 (43.9%) non-diarrheic (ND) cattle were rando...
متن کاملInteraction of Cryptosporidium hominis and Cryptosporidium parvum with primary human and bovine intestinal cells.
Cryptosporidiosis in humans is caused by the zoonotic pathogen Cryptosporidium parvum and the anthroponotic pathogen Cryptosporidium hominis. To what extent the recently recognized C. hominis species differs from C. parvum is unknown. In this study we compared the mechanisms of C. parvum and C. hominis invasion using a primary cell model of infection. Cultured primary bovine and human epithelia...
