The threats posed by a range of viral and bacterial zoonotic diseases inevitably receive renewed attention in the wake of global pandemic events due to their overt and devastating impacts on human health and the economy. Parasitic zoonoses, however, many of which affect millions of people each day, are frequently ignored. In the case of fasciolosis, caused by infection with Fasciola hepatica or Fasciola gigantica, this oversight has allowed for the expansion of areas of parasite sympatry and thus increased the incidence of hybridization and possible introgression between the two species. Here we highlight how an increased demand for animal-derived protein, combined with a lack of appropriate tools for detection of these events, is changing the status quo of these zoonotic parasites.

在全球大流行之后，由于一系列病毒和细菌性人畜共患疾病对人类健康和经济造成的破坏性影响，不可避免地引起了新的关注。但是，经常会忽略许多每天都影响数百万人的寄生虫性人畜共患病。如果是由肝片吸虫或巨大片吸虫感染引起的片虫病，这种疏忽使得寄生虫共生的区域扩大，从而增加了杂交的发生率，并增加了这两种物种之间的渗入。在这里，我们强调了对动物衍生蛋白质的需求增加，再加上缺乏适当的工具来检测这些事件，是如何改变这些人畜共患寄生虫的现状的。
