Prior to this study, only encapsulated species of Trichinella had been found in South America, i.e., T. spiralis and T. patagoniensis. Here we report the molecular identification of a non-encapsulated isolate of Trichinella from a domestic pig in Argentina. The multiplex PCR technique and the analysis of mitochondrial and nuclear DNA sequences revealed that it belongs to T. pseudospiralis, which parasitises birds and mammals from Australian, Nearctic, and Palaearctic regions. Interestingly, the isolate is closely related to the Palaearctic population. This is the first report of a non-encapsulated species of Trichinella from the Neotropical region.
在本研究之前，仅在南美洲发现过旋毛虫的包囊化种类，即旋毛形线虫和巴塔哥尼亚旋毛虫。在此我们报告从阿根廷一头家猪身上分离出的一种非包囊化旋毛虫的分子鉴定结果。多重PCR技术以及线粒体和核DNA序列分析表明，它属于伪旋毛虫，该种寄生于来自澳大利亚、新北区和古北区的鸟类和哺乳动物。有趣的是，该分离株与古北区种群密切相关。这是新热带区非包囊化旋毛虫种类的首次报道。
