Abstract

Studies on fish parasites in Pampulha dam, Belo Horizonte, Minas Gerais, Brazil, found specimens of Poecilia reticulata Peters, 1859 harboring natural infection by larval stages of tapeworms. A total of 250 specimens of P. reticulata were collected and analyzed between February and August 2010, of which 23 were found infected (prevalence 9.2%) with one metacestode each (mean intensity 1, mean abundance 0.09). The analyses of the parasites, particularly the morphology of rostellar hooks, made it possible to identify Glossocercus auritus (Rudolphi, 1818). This is the first report of G. auritus metacestode in South America and P. reticulata is a newly known host for this parasite.

摘要

对巴西米纳斯吉拉斯州贝洛奥里藏特潘普卢哈大坝鱼类寄生虫的研究发现，1859年的孔雀鱼（Poecilia reticulata Peters）标本感染了绦虫幼虫阶段的自然感染。2010年2月至8月期间，共收集并分析了250份孔雀鱼标本，其中23份被发现感染（患病率9.2%），每份标本感染一个中绦期幼虫（平均强度1，平均丰度0.09）。对寄生虫的分析，特别是对吻钩形态的分析，使得鉴定耳状舌形绦虫（Glossocercus auritus (Rudolphi, 1818)）成为可能。这是南美洲首次报道耳状舌形绦虫中绦期幼虫，孔雀鱼是这种寄生虫新发现的宿主。
