Abstract

Fasciola hepatica has a complex life cycle that includes a limnid snail as an intermediate host, where larval parthenogenetic multiplication occurs. We performed an experimental study of the life cycle of F. hepatica and estimated its potential biotic (r) in Galba truncatula. We selected 215 of these snails, and infected them with miracidia obtained at 26 ° C in the presence of light. We proceeded to dissect five snails every three days. By tracking the number of stages of F. hepatica by light microscopy observing external characteristics and development time of miracidia, sporocyst, rediae, and cercariae. We noted that the exponential growth model is best suited to the dynamics of F. hepatica. With a biotic potential of 6.69%, an average of 203 cercariae per miracidium and 270 cercariae per snail.
