Abstract
Spirometra Faust, Campbell et Kellogg, 1929 is a genus of cestodes belonging to the family Diphyllobothriidae. To date, amphibians, reptiles, and mammals are known second intermediate hosts of these parasites; humans can also be infected (the zoonotic disease is known as sparganosis or spirometrosis). Although the number of phylogenetic studies on Spirometra spp. has increased worldwide in recent years, there are few in South America. Specifically in Uruguay, molecular studies have shown that tapeworms of S. decipiens (Diesing, 1850) complexes 1 and 2 are present in this country. In this study, we characterised the larvae of Spirometra present in the annual fish Austrolebias charrua Costa et Cheffe. Phylogenetic analysis of the cytochrome c oxidase subunit I (COI) sequences of these larvae showed that they belong to S. decipiens complex 1. This is the first report of teleost fishes serving as a second intermediate host for tapeworms of the genus Spirometra in nature.
Spirometra Faust, Campbell et Kellogg, 1929是Diphyllobothriidae科的一个绦虫属。迄今为止,已知两栖动物、爬行动物和哺乳动物是这些寄生虫的第二中间宿主;人类也可被感染(人畜共患疾病被称为斯巴达病或螺旋体病)。尽管近年来世界范围内对螺虫的系统发育研究有所增加,但在南美洲却很少。特别是在乌拉圭,分子研究表明该国存在S. decipiens (Diesing, 1850)复合物1和2的绦虫。在这项研究中,我们描述了存在于一年生鱼Austrolebias charrua Costa et Cheffe中的螺虫幼虫。细胞色素c氧化酶亚基I (COI)序列的系统发育分析表明,这些幼虫属于S. decipiens复合体1。这是自然界首次报道硬骨鱼作为肺绦虫属绦虫的第二中间宿主。
期刊介绍:
FOLIA PARASITOLOGICA, issued in online versions, is an international journal that covers the whole field of general, systematic, ecological and experimental parasitology. It publishes original research papers, research notes and review articles. Contributions from all branches of animal parasitology, such as morphology, taxonomy, biology, biochemistry, physiology, immunology, molecular biology and evolution of parasites, and host-parasite relationships, are eligible. Novelty and importance in the international (not local or regional) context are required. New geographical records of parasites, records of new hosts, regional parasite and/or host surveys (if they constitute the principal substance of manuscript), local/regional prevalence surveys of diseases, local/regional studies on epidemiology of well known diseases and of parasite impact on human/animal health, case reports, routine clinical studies and testing of established diagnostic or treatment procedures, will not be considered. One species description will also not be considered unless they include more general information, such as new diagnostic characters, host-parasite associations, phylogenetic implications, etc. Manuscripts found suitable on submission will be reviewed by at least two reviewers.
