Considerable debate discusses the interactions of sea lice and wild and farmed salmon in British Columbia. Within this debate, the role of ectoparasitic sea lice in disease propagation (as a vector) or progression (impacts on the host's immunology) has not been described. Many models examine vector-pathogen relationships (e.g., pathogens transmitted by mosquitoes or ticks). However, these models focus on humans or agriculture animals and none exist for a marine ecosystem using fish. Few reports have isolated viral and bacterial pathogens from sea lice, but pathogen transmission has never been tested; thus, the role of sea lice as a vector remains undefined. In other words, when (seasonally) and where (geographically), could sea lice carry important pathogens of salmon? Such information is critical to the salmon farming industry. In a pilot study in British Columbia, Canada, we repeatedly isolated three pathogenic bacterial species from sea lice and their farmed

在不列颠哥伦比亚省，关于海虱与野生和养殖鲑鱼之间的相互作用存在相当大的争论。在这场辩论中，没有描述外寄生海虱在疾病传播（作为载体）或进展（对宿主免疫学的影响）中的作用。许多模型检查媒介-病原体关系（例如，由蚊子或蜱传播的病原体）。然而，这些模型主要针对人类或农业动物，而不存在针对使用鱼类的海洋生态系统的模型。很少有报道从海虱中分离出病毒和细菌病原体，但病原体的传播从未进行过测试;因此，海虱作为媒介的作用仍然不确定。换句话说，在何时（季节性）和何地（地理位置），海虱可以携带鲑鱼的重要病原体？这些信息对鲑鱼养殖业至关重要。在加拿大不列颠哥伦比亚省的一项试点研究中，我们反复从海虱及其养殖的
