In recent decades, worldwide fish consumption has increased notably worldwide. Despite the health benefits of fish consumption, it also can suppose a risk because of fishborne diseases, including parasitic infections. Global changes are leading to the emergence of parasites in new locations and to the appearance of new sources of transmission. That is the case of the zoonotic protozoa spp., , and ; all of them reach aquatic environments and have been found in shellfish. Similarly, these protozoa can be present in other aquatic animals, such as fish. The present review gives an overview on these three zoonotic protozoa in order to understand their potential presence in fish and to comprehensively revise all the evidences of fish as a new potential source of spp., , and transmission. All of them have been found in both marine and freshwater fishes. Until now, it has not been possible to demonstrate that fish are natural hosts for these protozoa; otherwise, they would merely act as mechanical transporters. Nevertheless, even if fish only accumulate and transport these protozoa, they could be a "new" source of infection for people.
近几十年来，全球鱼类消费量显著增加。尽管食用鱼类有益健康，但由于食源性疾病，包括寄生虫感染，它也可能带来风险。全球变化导致寄生虫在新的地点出现，并出现新的传播源。人畜共患原生动物 spp.、 和 就是这种情况；它们都进入水生环境，并已在贝类中被发现。同样，这些原生动物也可能存在于其他水生动物中，如鱼类。本综述概述了这三种人畜共患原生动物，以便了解它们在鱼类中的潜在存在，并全面修订鱼类作为 spp.、 和 传播新潜在来源的所有证据。它们在海水鱼和淡水鱼中均有发现。到目前为止，还无法证明鱼类是这些原生动物的自然宿主；否则，它们仅仅起到机械传播者的作用。然而，即使鱼类只是积累和传播这些原生动物，它们也可能成为人类“新”的感染源。
