title: [Infectious etiology of acute idiopathic intussusception in children].
abstract: The intussusception (IIA) is an invagination of the immediate part of the intestine. She is responsible for a syndrome with an occlusive venous compression and swelling that can rapidly progress to intestinal necrosis. Most cases occur in children aged 6 to 18 months and occur more frequently in boys than girls. There are two types of IIA: the IIA idiopathic representing 90-95% of invaginations of the child and the IIA secondary to local injury of the gastrointestinal tract or occurring in a particular context whose frequency are between 5 and 10%. The pathogenesis of the IIA remains uncertain, but the infectious origin is criminalized in most idiopathic invaginations. This component is dominated by viral agents including adenovirus, rotavirus, enterovirus, human herpesvirus 6 and 7, cytomegalovirus and Epstein-Barrvirus. Bacterial agents are rather found and include Yersinia enterocolitica, Staphylococcus aureus, Escherichia coli O157, H7, Salmonella and Campylobacter. In a small proportion parasitic agents may be reported in the IIA, the most frequently found are Entamoeba histolytica, Trichuris trichuira, Ascaris lumbricoides, Ankylostoma and Giardia.
