Travellers' diarrhea afflicts up to 50 percent of tourists in certain geographic regions. It is a syndrome caused by a variety of pathogens, the most common of which is enterotoxigenic E. coli. Other responsible pathogens include salmonellae, shigellae, Entamoeba histolytica, Yersinia enterocolitica, Giardia lamblia and virus-like agents, seldom vibrios. Symptoms persist for only a few days and are only serious in 1/5 of the cases. 相似文献

Authors of article have recently analyzed the frequency of prevalence and risk factors of cross-reactivity to foodstuffs among 239 children of Abakan in the age of from 6 months till 15 years with skin, respiratory and combined manifestation of atopy. It was proved that risk factors of development of cross-reactivity to food among children of the first years of life are hereditary predisposition to allergic diseases (77.8%) and early introductions of supplemental feeding (44%). Among children older then 7 years pollen sensitization (62%) which preceded the development of cross allergic reactions between separate foodstuffs reaches up to 73.7%, between pollen and foodstuff up to 79% and between epidermal and food up to 10.1%. 相似文献
