Migration through host tissues has major costs for parasitic helminths in terms of energy expenditure, risks of attrition and the need to adapt to varying physicochemical environments. Nevertheless, such migratory phases seem to confer a specific survival advantage. One reason for this might be the avoidance of specific host immune-defence mechanisms designed to protect against threats at mucosal surfaces.
对于寄生性蠕虫而言，在宿主体内组织中移行在能量消耗、损耗风险以及适应不同物理化学环境的需求方面代价高昂。然而，这样的移行阶段似乎赋予了特定的生存优势。其原因之一可能是避开了旨在抵御黏膜表面威胁的特定宿主免疫防御机制。
