Alveolar echinococcosis is a serious zoonosis caused by the larval stage of Echinococcus multilocularis. Pigs, as humans, can play the role of non-specific intermediate hosts of this parasite. Detection of E. multilocularis in swine can be taken as an indicator of infection risk for humans. This paper presents the first cases where E. multilocularis larval forms have been detected in pigs in Poland. A total of 256 pig livers with different lesions were collected from slaughterhouses in southern Poland and examined by nested PCR method. Three of them were identified as E. multilocularis positive. They contained noticeable spherical nodular whitish forms on the surface of the liver, recessed partially into the liver tissue. In two cases only single lesions (3mm and 6mm in diameter) were found, while in one case numerous (eight) lesions (2mm in diameter) were found. PCR E. multilocularis identification was confirmed by sequencing and comparison with the GenBank database.
泡型包虫病是一种由细粒棘球绦虫幼虫引起的严重人畜共患病。猪作为人类，可以扮演这种寄生虫非特异性中间宿主的角色。在猪中检测到细粒棘球绦虫可以作为人类感染风险的指标。本文报道了波兰首次在猪中检测到细粒棘球绦虫幼虫的病例。从波兰南部的屠宰场共收集了 256 个具有不同病变的猪肝脏，并通过巢式 PCR 方法进行了检查。其中 3 个被鉴定为细粒棘球绦虫阳性。它们在肝脏表面有明显的球形结节状白色形式，部分凹陷到肝组织中。在 2 例中仅发现单个病变（直径为 3mm 和 6mm），而在 1 例中发现多个（8 个）病变（直径为 2mm）。通过测序并与 GenBank 数据库进行比较，确认了 PCR 细粒棘球绦虫鉴定。
