Abstract

Trichinellosis is a parasitic disease affecting various mammals (including humans), birds, and reptiles, and is widespread across multiple continents except Antarctica. The disease can be caused by several species of the genus Trichinella and there are documented cases of T. britovi globally.

In Algeria, human cases of Trichinella have been reported and a study identifying T. britovi linked the infection to the consumption of jackal meat., with no reports of Trichinella spp. in animals. This preliminary study aimed to investigate the presence of Trichinella spp. infection among carnivorous species in Algeria.

Between February 2022 and August 2023, 33 road-killed mammals, mainly carnivores were collected from different locations across five departments: El Tarf, Annaba, Constantine, Algiers, and Oued Souf. Comprehensive parasitological necropsies were conducted, and muscle samples from the dorsal and ventral musculature of the forelimb and the diaphragm of each animal were examined using trichinoscopy. DNA was isolated from positive muscle tissue samples and analyzed using multiplex polymerase chain reaction (PCR).

Trichinella spp. cysts were detected in one domestic dog (Canis familiaris) from Ain Kerma, El Tarf. Molecular analysis confirmed all cysts as T. britovi. This study presents the first report of the genus T. britovi in an animal host in Algeria, highlighting the role of domestic dogs in maintaining the sylvatic life cycle of T. britovi in the region.

首次在阿尔及利亚的一只家犬（Canis familiaris）身上发现布氏旋毛虫（Trichinella britovi）。

旋毛虫病是一种影响各种哺乳动物（包括人类）、鸟类和爬行动物的寄生虫病，广泛分布于除南极洲以外的各大洲。在阿尔及利亚，曾有人类感染旋毛虫病例的报道，一项发现布里托维旋毛虫的研究将感染与食用豺肉联系起来，但没有动物感染旋毛虫的报道。2022 年 2 月至 2023 年 8 月期间，在阿尔及利亚五个省的不同地点收集了 33 只路杀哺乳动物，主要是食肉动物：在 2022 年 2 月至 2023 年 8 月期间，在阿尔及利亚塔夫、安纳巴、君士坦丁、阿尔及尔和 Oued Souf 五个省的不同地点收集了 33 只路杀哺乳动物，主要是食肉动物。对每只动物进行了全面的寄生虫尸体解剖，并使用毛虫镜检查了每只动物前肢背侧和腹侧肌肉组织以及膈肌的肌肉样本。从阳性肌肉组织样本中分离出 DNA，并使用多重聚合酶链式反应 (PCR) 进行分析。分子分析证实所有囊蚴均为布氏毛癣菌（T. britovi）。本研究首次报告了阿尔及利亚动物宿主体内的布氏毛癣菌（T. britovi），突出了家犬在维持布氏毛癣菌（T. britovi）在该地区的系统生命周期中的作用。

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).
