Abstract

Paratanaisia spp. is a trematode from Eucotylidae family that parasites kidneys and ureters of many bird species. Epidemiology and histopathology associated with parasitism remains poorly understood in wild birds. The aim of this study was to investigate Paratanaisia-elicited lesions, parasite species identification, and assessment of host species among free-ranging or wild bird species kept under human care. Kidney samples from 196 necropsied free-ranging or captive wild birds from the States of Minas Gerais and São Paulo, Brazil, were included in this study. Parasitism was observed in ten birds, from both zoological institutions, including seven different species, two of which with no previous report of Paratanaisia infection, namely one Icterus jamacaii and one Crypturellus noctivagus. Sequencing of PCR amplicons from two birds demonstrated 100 % cover and identity with P. bragai. The orders Galliformes and Passeriformes had a significantly higher frequency of parasitism when compared to Psittaciformes. Therefore, this study expands our knowledge on the prevalence and host spectrum of Paratanaisia spp.

野生鸟类的副绦虫感染：组织学和分子特征，以及新的寄主物种

巨吸虫是一种寄生于鸟类肾脏和输尿管的巨吸虫。在野生鸟类中，与寄生虫有关的流行病学和组织病理学仍然知之甚少。本研究的目的是调查人类饲养的自由放养和野生鸟类中寄生虫诱发的病变、寄生虫种类鉴定和宿主种类评估。来自巴西米纳斯吉拉斯州和圣保罗州的196只死亡的自由放养或圈养野生鸟类的肾脏样本被纳入本研究。在两所动物机构的10只鸟类（包括7个不同种）中观察到寄生，其中2只鸟类（1只牙买加Icterus jamaii和1只夜隐鸟Crypturellus noctivagus）以前未报道过寄生感染。从两只鸟的PCR扩增子测序证实了100%的覆盖和同源性。加利形目和雀形目的寄生频率明显高于鹦鹉形目。因此，本研究扩大了我们对Paratanaisia spp患病率和寄主谱的认识。

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).
