摘要

旋毛虫病是由旋毛虫复合体线虫引起的一种全球传播的食源性寄生虫病。在进化过程中,在生态相互作用、自然选择和生化“智能”的指导下,这些寄生虫发展出了令人钦佩的策略来感染宿主的有机体。其中最引人注目的是肌肉组织(如横膈膜、骨骼肌、外源性眼肌等)中护士细胞的形成。这种策略使寄生虫能够适应并征服更广泛的宿主物种,包括有蹄类动物和人类。食用未煮熟的受感染野生有蹄类动物的肉是人类最重要的感染源。在这项研究中,我们展示了旋毛虫在意大利中部被猎杀野猪(Sus scrofa)中的流行情况。在Rieti省2021/2022年狩猎季节,根据欧盟1375/2015条例,收集了554份野猪横膈膜活检标本,用于旋毛虫筛查。采用人工消化法检测旋毛虫幼虫。检测结果为0.18%(1/554),分子生物学鉴定证实阳性样品中存在布氏旋毛虫。该物种在意大利中部野生有蹄类动物种群中分布最广,在该地区人类旋毛虫病患者中最常分离到,表明在生态系统中旋毛虫传播方面,智人与苏氏螺旋体之间存在密切的流行病学关系。在供人类食用的易受感染动物物种中进行流行病学监测,是控制这种世界范围内广泛传播的食源性寄生虫病的主要“制胜”战略。

<i>Trichinella</i> spp. detection in hunted wild boar (<i>Sus scrofa</i>) diaphragm biopsies in Central Italy
Trichinellosis is a globally diffused food-borne parasitic disease caused by nematodes of the Trichinella complex. During evolution, guided by ecological interactions, natural selection, and biochemical “intelligence”, these parasites developed admirable strategies to infect the host’s organism. One of the most fascinating is represented by the nurse cell formation in muscular tissue (e.g., diaphragm, skeletal muscle, extrinsic ocular muscles, etc.). This strategy allowed the parasite to adapt and conquer the wider host species spectrum, including ungulates and humans. Consumption of undercooked meat from infected wild ungulates constitutes the most important source of infection for the human species. In this study, we show the prevalence of Trichinella spp. in hunted wild boars (Sus scrofa) in Central Italy. During the hunting season 2021/2022 in the Province of Rieti, 554 wild boar diaphragm biopsies were collected for Trichinella spp. screening, in accordance with Regulation EU 1375/2015. An artificial digestion method was used for the detection of Trichinella spp. larval forms. The results revealed a positivity of 0.18% (1/554), and molecular biology identification demonstrated the presence of Trichinella britovi in the positive sample. This species is the most diffused in wild ungulate populations in Central Italy and the most frequently isolated in human patients with trichinellosis from this area, showing a close epidemiological relation between Homo sapiens and Sus scrofa for Trichinella spp. diffusion in an ecosystem. Epidemiological surveillance, in receptive animal species destined for human consumption and at any One Health level, represents the main “winning” strategy in the control of this worldwide, widespread food-borne parasitic disease.
