Food-borne parasitic diseases, many known to be more prevalent in poor countries with deficient sanitary conditions, are becoming common worldwide. Among the emerging protozoan parasites, the most prominent is Trypanosoma cruzi, rarely reported in the past to be transmitted by the oral route but currently responsible for frequent outbreaks of acute cases of Chagas disease contracted orally and characterized by high mortality. Several other food-borne protozoans considered emerging include the apicomplexans Toxoplasma gondii and Cryptosporidium, as well as Giardia and Entamoeba histolytica. Here, the interactions of these protozoans with the mucosal epithelia of the host are discussed.
食源性寄生虫病，许多在卫生条件差的贫穷国家更为普遍，现在在全球范围内也变得很常见。在新出现的原生动物寄生虫中，最为突出的是克氏锥虫，过去很少有报道称其经口服途径传播，但现在却经常引起由口服途径感染、死亡率高的急性恰加斯病暴发。还有一些被认为是新出现的食源性原生动物，包括顶复门的刚地弓形虫和隐孢子虫，以及蓝氏贾第鞭毛虫和溶组织内阿米巴。本文讨论了这些原生动物与宿主黏膜上皮的相互作用。
