Abstract

The Chiloe wigeon, Mareca sibilatrix (Anseriformes: Anatidae), is a native duck distributed mainly in Chile and Argentina. Although it is a common species in the Neotropical realm, studies on its parasitic fauna remain limited. This study aimed to gather additional data on host-parasite associations in M. sibilatrix. Thus, 18 birds from Ñuble region, central Chile, were subjected to parasitic examination. Ectoparasites and endoparasites obtained were stored in 70 % and 80 % ethanol, respectively. A total of 787 parasite individuals were isolated; all birds were parasitized by at least one parasite. In 14 (77.7 %) birds, a total of 179 ectoparasites belonging to six taxa were identified. Meanwhile, all dissected birds (100 %) harbored a total of 608 endoparasites belonging to 15 taxa. Ectoparasites corresponded to four taxa of chewing lice (four genera) and two feather mites (two genera). Meanwhile, endoparasites were represented by four tapeworms (four genera), five trematodes (four genera), five nematodes (five genera), and one nasal mite. Of recorded parasite species, two taxa represent new records to the Neotropical realm, 11 taxa (three ectoparasites and eight endoparasites) are new records for the parasitic fauna of Chile, and 15 taxa (three ectoparasites and twelve endoparasites) are recorded for the first time in M. sibilatrix. Additionally, the fluke Echinostoma echinatum is of zoonotic concern. This research contributes with valuable data to the understanding of parasitic diversity in waterfowl and emphasizes the role of M. sibilatrix as a host in various parasitic interactions within its distribution range.

文章标题智利Ñuble地区赤蛾的寄生动物群（雁形目：鸭科）。

智利野鸭（mreca sibilatrix，雁形目：鸭科）是一种主要分布在智利和阿根廷的本地鸭。虽然它是新热带地区常见的物种，但对其寄生区系的研究仍然有限。本研究的目的是收集更多的数据，寄主-寄生虫的联系在sibilatrix。因此，来自智利中部Ñuble地区的18只鸟进行了寄生虫检查。体外寄生虫和体内寄生虫分别保存在70%和80%的乙醇中。共分离到寄生虫787只；所有的鸟都至少被一种寄生虫所寄生。在14只（77.7%）鸟类中，共鉴定出6个类群179种体外寄生虫。同时，所有解剖鸟类（100%）共携带608种内寄生虫，隶属于15个分类群。体表寄生虫与咀嚼虱（4属）4个类群和羽螨（2属）对应。内寄生虫有绦虫4属、吸虫4属、线虫5属和鼻螨1属。其中2个为新热带地区新记录，11个为智利寄生虫区系新记录，3个为外寄生区系，8个为内寄生区系，15个为首次记录，3个为外寄生区系，12个为内寄生区系。此外，棘突吸虫是人畜共患的问题。本研究为了解水禽的寄生多样性提供了有价值的数据，并强调了在水禽分布范围内，水鸟寄生体作为寄主在各种寄生相互作用中的作用。

期刊介绍： Veterinary Parasitology: Regional Studies and Reports focuses on aspects of veterinary parasitology that are of regional concern, which is especially important in this era of climate change and the rapid and often unconstrained travel of people and animals. Relative to regions, this journal will accept papers of the highest quality dealing with all aspects of disease prevention, pathology, treatment, epidemiology, and control of parasites within the field of veterinary medicine. Also, case reports will be considered as they add to information related to local disease and its control; such papers must be concise and represent appropriate medical intervention. Papers on veterinary parasitology from wildlife species are acceptable, but only if they relate to the practice of veterinary medicine. Studies on vector-borne bacterial and viral agents are suitable, but only if the paper deals with vector transmission of these organisms to domesticated animals. Studies dealing with parasite control by means of natural products, both in vivo and in vitro, are more suited for one of the many journals that now specialize in papers of this type. However, due to the regional nature of much of this research, submissions may be considered based upon a case being made by the author(s) to the Editor. Circumstances relating to animal experimentation must meet the International Guiding Principles for Biomedical Research Involving Animals as issued by the Council for International Organizations of Medical Sciences (obtainable from: Executive Secretary C.I.O.M.S., c/o W.H.O., Via Appia, CH-1211 Geneva 27, Switzerland).
