摘要: The behavioral repertoire of the infective stage Fasciola hepatica was qualitatively characterized. During activation, a primary activity emptying ceca by peristaltic-like contractions. Emergence behavior comprised coordinated patterns body movement and sucker specifically directed at disruption ventral plug. stimulus specificity emergence response for glycine-conjugated cholic acid log dose-effect relationship this with glycocholic suggested receptor-mediated sensory recognition. Extracts from duodenum (departure organ) liver (arrival site) significantly affected rate locomotion orientation migratory stage. evidence in migrating stages is unequivocal, but mechanisms which they orient are unclear.
