摘要

根据罗马尼亚家犬(Canis familiaris)的模式标本、实验感染猫(Felis catus)的标本以及金色仓鼠(Mesocricetus auratus)感染鲢鱼(Squalius cephalus)和普通鳢(Chondrostoma nasus)(鲤形目:Leuciscidae)感染。这种欧洲及邻近地区(土耳其西北部)特有的吸虫以前曾被误认为是东亚人畜共患寄生虫 M. yokogawai(Katsurada,1912 年)。然而,这两个物种在遗传学和形态学上都有很大不同,例如腹吸盘的位置、前咽的存在、卵黄卵泡的前部范围和子宫的后部范围。Metagonimus ciureanus(Witenberg,1929)(同义词:Dexiogonimus ciureanus Witenberg,1929),描述自以色列的家猫和家犬,是分布于中东和外高加索地区的有效物种,分子数据也证实了这一点。它与包括 M. romanicus 在内的所有 Metagonimus 物种的不同之处在于,它的睾丸是对称的,而不是其他同属种的斜睾丸。M.romanicus和M.ciureanus的人畜共患病意义尚不清楚,但在欧洲似乎较低,主要是因为人们一般不食用生的或未煮熟的带鳞全鱼。渔民在清洗鱼类时不小心被鱼鳞中的甲虫感染的可能性更大,但从未有过报道。带鳞片的鲤科鱼类残骸感染了鲭属元孢子虫,可能成为狗、猫和其他食肉动物的重要天然传染源,它们可能成为这些寄生虫的贮存库。

Small intestinal flukes of the genus Metagonimus (Digenea: Heterophyidae) in Europe and the Middle East: A review of parasites with zoonotic potential.

The heterophyid trematode Metagonimus romanicus (Ciurea, 1915) (Digenea) is redescribed on the basis of type material from domestic dogs (Canis familiaris) in Romania, vouchers from experimentally infected cats (Felis catus) and adults recovered from golden hamsters (Mesocricetus auratus) infected with metacercariae from scales of chub (Squalius cephalus) and common nase (Chondrostoma nasus) (Cypriniformes: Leuciscidae) in Hungary. This trematode, endemic to Europe and neighbouring regions (northwestern Türkiye), was previously misidentified as M. yokogawai (Katsurada, 1912), a zoonotic parasite of humans in East Asia. However, the two species differ considerably both genetically and morphologically, e.g., in the position of the ventral sucker, the presence of the prepharynx, the anterior extent of the vitelline follicles and the posterior extent of the uterus. Metagonimus ciureanus (Witenberg, 1929) (syn. Dexiogonimus ciureanus Witenberg, 1929), described from domestic cats and dogs in Israel, is a valid species distributed in the Middle East and Transcaucasia, which is also confirmed by molecular data. It differs from all Metagonimus species, including M. romanicus, in having symmetrical testes instead of the oblique testes of the other congeners. The zoonotic significance of M. romanicus and M. ciureanus is unclear, but appears to be low in Europe, mainly because raw or undercooked, whole fish with scales are generally not consumed. Accidental infection of fishermen by metacercariae in the scales when cleaning fish is more likely, but has never been reported. Remains of cyprinoids with scales infected with metacercariae of Metagonimus spp. can be an important natural source of infection for dogs, cats, and other carnivores, which can serve as a reservoir for these parasites.

期刊介绍: Parasite is an international open-access, peer-reviewed, online journal publishing high quality papers on all aspects of human and animal parasitology. Reviews, articles and short notes may be submitted. Fields include, but are not limited to: general, medical and veterinary parasitology; morphology, including ultrastructure; parasite systematics, including entomology, acarology, helminthology and protistology, and molecular analyses; molecular biology and biochemistry; immunology of parasitic diseases; host-parasite relationships; ecology and life history of parasites; epidemiology; therapeutics; new diagnostic tools. All papers in Parasite are published in English. Manuscripts should have a broad interest and must not have been published or submitted elsewhere. No limit is imposed on the length of manuscripts, but they should be concisely written. Papers of limited interest such as case reports, epidemiological studies in punctual areas, isolated new geographical records, and systematic descriptions of single species will generally not be accepted, but might be considered if the authors succeed in demonstrating their interest.
