Les étiologies infectieuses des diarrhées du voyageur

摘要: Traveler's diarrhoea (TD) occurs in 20 to 60% of European or North-American travelers intertropical areas. Following return from endemic zone, malaria must always be evocated front febrile diarrhoea. Many causative infectious agents are involved TD and their frequency may vary according destination seasons. The main Escherichia coli pathovars (especially enterotoxigenic enteroaggregative E. coli) followed by enteroinvasive bacteria (Campylobacter spp., Shigella Salmonella enterica), enteric viruses (norovirus, rotavirus) protozoa (Gardia intestinalis, Cryptosporidium parvum et Entamoeba histolytica). development molecular biology methods as PCR allow us evaluate the relative these especially viral TD. Protozoa microsporidia more frequently isolated persistent chronic TD, compromised patients. A complete etiological research routine microbiology laboratories is difficult time-consuming, related high diversity need for specific methods. Implementation laboratory diagnosis highly recommended when associated with fever presence blood stools, immunosuppression, antibiotic treatment (Clostridium difficile toxins) case persistent/chronic According acquired antibiotic-resistance bacteria, an antibiogram performed all bacterial agents.
