Sanitary management and population control of feral pigs remains a major problem in public health, particularly in natural parks where hunting is prohibited and the extensive farming of livestock is common. is a zoonotic parasite species with a worldwide distribution of which the natural definitive hosts are primarily pigs and wild boars (). The present study describes the main anatomo-pathological and parasitological findings in the first case of in feral pigs in the Madonie park in Sicily (Southern Italy). Overall, 52 acanthocephalans were collected from the small intestine of four infected feral pigs. The prevalence among the 36 examined animals was 11.1% with a mean Abundance (mA) and mean Intensity (mI) of 1.4 and 13, respectively. Pathological examination revealed grossly visible nodules on the external surface of the intestines, corresponding to the proboscis of attached deeply into the intestinal wall. In these sites, severe inflammatory reactions in the tissue involved and the destruction of normal intestinal architecture, as well as necrosis and ulceration in the mucosa, submucosa, and part of the were described. This is the first official report of this neglected zoonosis in Italy, in particular in a natural park where the extensive farming of domestic pigs is practiced. This could favor the spread of this parasite in domestic animals and the environment, increasing the accidental risk of infection in human residents of these areas.
野猪的卫生管理和种群控制仍然是公共卫生领域的一个主要问题，特别是在禁止狩猎且普遍存在大规模家畜养殖的自然公园。是一种人畜共患寄生虫物种，在全球范围内分布，其自然终末宿主主要是猪和野猪（）。本研究描述了意大利南部西西里岛马多尼公园野猪首例感染病例的主要解剖病理学和寄生虫学发现。总体而言，从4头受感染野猪的小肠中收集到52只棘头虫。在36只检查动物中，感染率为11.1%，平均丰度（mA）和平均强度（mI）分别为1.4和13。病理检查发现肠道外表面有肉眼可见的结节，对应于深深嵌入肠壁的棘头虫吻突。在这些部位，描述了受累组织中的严重炎症反应、正常肠道结构的破坏以及黏膜、黏膜下层和部分肌层的坏死和溃疡。这是意大利首次关于这种被忽视的人畜共患病的官方报告，特别是在一个实行大规模家猪养殖的自然公园。这可能有利于这种寄生虫在家畜和环境中的传播，增加这些地区人类居民意外感染的风险。
