This study was carried out in southern Portugal to determine the prevalence of parasitic helminths infecting wild birds. Between September and December of 2013, adult parasites were collected from the gastrointestinal tract of 22 bird specimens (belonging to 12 species) that died in Wildlife Rehabilitation and Investigation Centre of the Ria Formosa. Identified gastrointestinal parasites include the nematodes (Contracaecum sp., Cosmocephalus obvelatus, Desportesius invaginatus, Dispharynx nasuta, Porrocaecum angusticolle and Synhimantus laticeps) and cestodes (Diplophallus sp., Neyraia intricata and Tetrabothrius sp.). The overall level of infection was 54.5% (12/22) and the most frequent helminths present were nematodes (40.9% - 9/22), followed by cestodes (13.6% - 3/22). Helminthic richness was similar in all birds (one species or genera per bird) and the helminth species, except Dispharynx nasuta, exhibited a clear relationship with host diet. Five helminth species (Cosmocephalus obvelatus, Desportesius invaginatus, Dispharynx nasuta, Porrocaecum angusticolle and Neyraia intricata) and two genera (Contracaecum sp. and Diplophallus sp.) were reported for the first time in Portugal and the presence of P. angusticolle in Bonelli's eagle was recorded for the first time across all researched literature.
本研究在葡萄牙南部开展，以确定感染野生鸟类的寄生蠕虫的流行情况。2013年9月至12月期间，从在福尔摩沙湾野生动物康复与调查中心死亡的22只鸟类标本（分属于12个物种）的胃肠道中收集成年寄生虫。鉴定出的胃肠道寄生虫包括线虫（Contracaecum属、Cosmocephalus obvelatus、Desportesius invaginatus、Dispharynx nasuta、Porrocaecum angusticolle和Synhimantus laticeps）和绦虫（Diplophallus属、Neyraia intricata和Tetrabothrius属）。总体感染率为54.5%（12/22），最常见的蠕虫是线虫（40.9% - 9/22），其次是绦虫（13.6% - 3/22）。所有鸟类的蠕虫丰富度相似（每只鸟一种或一个属），除Dispharynx nasuta外，蠕虫种类与宿主饮食呈现明显关系。有五种蠕虫（Cosmocephalus obvelatus、Desportesius invaginatus、Dispharynx nasuta、Porrocaecum angusticolle和Neyraia intricata）和两个属（Contracaecum属和Diplophallus属）在葡萄牙首次被报道，并且在所有研究文献中首次记录到Bonelli's鹰体内存在Porrocaecum angusticolle。
