摘要

尽管在犬科动物的肌肉中，肌囊性囊肿并不常见，但我们在美国阿拉斯加的49只灰狼（Canis lupus arctos）的20只（40.8%）的舌头中发现了成熟的肌囊性囊肿。检测到两种类型的结节囊肿（薄壁和厚壁）；根据肌囊壁的外观，它们与家犬的犬性肌囊菌和犬性肌囊菌相似。49只狼中有18只被鉴定为厚壁囊肿，49只狼中有3只被鉴定为薄壁囊肿。分子上，利用18S rRNA、28S rRNA、cox1和rpoB遗传标记对肉囊菌进行了分子表征。所有这些标记与先前从家犬中描述的犬链球菌或svanai具有99%的一致性。49只灰狼的舌头组织切片中检出旋毛虫幼虫7只（14.2%）。

High prevalence of Sarcocystis and Trichinella infections in skeletal muscles of gray wolves (Canis lupus arctos) from Alaska, USA

Although cysts of Sarcocystis spp. (sarcocysts) are considered uncommon in muscles of canids, we identified mature sarcocysts in tongues of 20 (40.8 %) of 49 gray wolves (Canis lupus arctos) from Alaska, USA. Two kinds of sarcocysts (thin-walled and thick-walled) were detected; based on the appearance of the sarcocyst wall, they resembled Sarcocystis caninum and Sarcocystis svanai of the domestic dog (Canis familiaris). Thick-walled cysts were identified in 18 of 49 wolves and thin-walled were seen in three of 49 wolves. Molecularly, Sarcocystis species were characterized using 18S rRNA, 28S rRNA, cox1 and rpoB genetic markers. All these markers showed >99 % identity to either of S. caninum or S. svanai described previously from the domestic dog. Trichinella spp. larvae were found in histological sections of tongues of 7 (14.2 %) of 49 gray wolves.

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).
