摘要

肝片吸虫是一种全球分布的吸虫寄生虫，在各种哺乳动物宿主中发现，最明显的是反刍动物。它与肝脏病变有关，包括坏死和炎症，并可增加继发性细菌感染的风险。在北美缺乏马科动物的片形吸虫病报告。本报告记录了美国德克萨斯州南部驴中两例慢性筋膜吸虫病的死前和死后发现。大体可见左肝叶萎缩，同时右肝叶肥大。肝脏的组织学检查显示典型的管内吸虫成虫和卵，并伴有胆道增生和纤维化。

Fasciola hepatica in donkeys from southern Texas, USA

Fasciola hepatica is a trematode parasite with a global distribution found in various mammalian hosts, most notably ruminants. It is associated with hepatic lesions including necrosis and inflammation, as well as can increase the risk of secondary bacterial infections. There is a lack of reports of fasciolosis in equids in North America. This report documents the pre- and postmortem findings of two cases of chronic fasciolosis in donkeys from southern Texas, United States. Grossly, left hepatic lobe atrophy and concurrent right lobe hypertrophy was observed. Histologic examination of the liver showed classic findings of intra-ductular trematode adults and eggs with biliary hyperplasia and fibrosis.

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).
