During a study on the epidemiology of trichinellosis in Spain, 91 animals and 9 samples of sausages homemade with pork were found positive for Trichinella. Parasite identification at the species level was carried out by the polymerase chain reaction with a random primer on single muscle larvae. Seventy-one animals harbored Trichinella spiralis (17 domestic pigs, 53 wild boars, 1 fox), and 17 were infected with Trichinella britovi (1 domestic pig, 13 wild boars, 3 foxes). Sausages were infected with T. spiralis. Three wild boars (3.3% of infected animals) harbored both species. The presence of both T. spiralis and T. britovi in the same host suggests that infections with 2 isolates of the same species can also occur, permitting the gene flow within the species.
在一项关于西班牙旋毛虫病流行病学的研究中，发现91只动物和9份自制猪肉香肠样本旋毛虫呈阳性。通过对单个肌肉幼虫使用随机引物进行聚合酶链反应，在物种水平上进行寄生虫鉴定。71只动物感染旋毛形线虫（17头家猪、53头野猪、1只狐狸），17只感染布氏旋毛虫（1头家猪、13头野猪、3只狐狸）。香肠感染了旋毛形线虫。3头野猪（占感染动物的3.3%）同时感染了这两种物种。同一宿主中同时存在旋毛形线虫和布氏旋毛虫表明，同一物种的2个分离株感染也可能发生，这使得物种内的基因流动成为可能。
