Filter by:Cryptosporidium species are increasingly recognized as important enteric pathogens that infect a broad range of hosts including human, domestic and wild animals worldwide, causing asymptomatic or mild-to-severe gastrointestinal disease in their host species. There are 38 species of Cryptosporidium that have been described, going from amphibian parasites to mammals ones, with over 40 genotypes infecting mammals, although Cryptosporidium parvum and Cryptosporidium hominis are the two species predominantly reported in human infections. In Cairo and Sharkyia governorates in Egypt, Cryptosporidium is a common intestinal parasite among children, especially in diarrheic, preschool-aged children, with a predominance of C. hominis indicates anthroponotic rather than zoonotic transmission. Also in the sohag governorate, Cryptosporidium infection is a common intestinal parasite, as in the last five years its prevalence about 35% but there is no study clarify predominant genotype of Cryptosporidium in sohag.
It has been reported that Cryptosporidium parvum, a species of a protozoan frequently isolated from humans and animals, is able to induce digestive adenocarcinoma in a rodent model. Consistently, some epidemiological studies have reported an association with cryptosporidiosis in patients with colorectal adenocarcinoma. However, the correlation between cryptosporidiosis and human digestive cancer remains unclear at this time, and it is not known whether this intracellular parasite, considered an opportunistic agent, is able to induce gastrointestinal malignancies in humans. In order to add new arguments for a probable association between cryptosporidiosis and digestive human cancer, the main aim of this study is to determine prevalence and to identify species of Cryptosporidium among a French digestive cancer population.
