Abstract

Hymenolepis nana (H. nana) is a zoonotic parasite with a global distribution. Hamsters are a common household pet and have been widely domesticated. H. nana is a prevalent tapeworm that parasitizes the small intestine of hamsters. However, there are few recent reports on whether pet hamsters in urban areas are infected with H. nana and the morphological characteristics of different developmental stages of the parasite. This study employed a combination of morphological and molecular biological approaches, utilizing pathological staining to investigate the helminth infection of pet hamsters in Guiyang, China, and the subsequent histopathological damage it caused. The results confirmed the presence of H. nana, and its average infection rate was as high as 256/359 (71.31 %), revealing that its different developmental stages exhibit distinct parasitic sites. Cysticercoids were found to parasitize the intestinal villi, while adult worms resided in the intestinal lumen, with the latter causing more severe pathological damage. Our study updates data on the prevalence of H. nana in Guiyang, China, as well as the morphological characteristics of H. nana at various developmental stages and the associated histopathological changes in the small intestine of pet hamsters.

贵阳地区宠物仓鼠肠道膜膜绦虫鉴定及组织病理学评价

膜膜绦虫（H. nana）是一种全球分布的人畜共患寄生虫。仓鼠是一种常见的家庭宠物，已被广泛驯养。娜娜绦虫是一种普遍存在的绦虫，寄生在仓鼠的小肠上。然而，近年来关于城市宠物仓鼠是否感染纳纳氏绦虫以及纳纳氏绦虫不同发育阶段形态特征的报道较少。本研究采用形态学和分子生物学相结合的方法，利用病理染色法对贵阳地区宠物仓鼠的蠕虫感染情况及其引起的组织病理学损伤进行了研究。结果证实了该蚊的存在，其平均感染率高达256/359(71.31%)，表明其不同发育阶段有不同的寄生位点。囊虫寄生在肠绒毛上，成虫寄生在肠腔内，后者造成更严重的病理损伤。我们的研究更新了中国贵阳地区娜娜家鼠的流行情况，以及不同发育阶段娜娜家鼠小肠的形态特征和相关的组织病理学变化。

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).
