Excystation in vitro of Echinostoma liei and E. revolutum (Trematoda) metacercariae



Excystation in vitro of Echinostoma liei and E. revolutum (Trematoda) metacercariae



Journal of Parasitology 74(1): 98-102



Metacercariae of E. liei and E. revolutum were excysted in an alkaline bile-trypsin medium at 41 degrees C in the absence of acid-pepsin pretreatment. After 60 min at a pH of 7.8 or 8.0, excystation of E. liei reached 98%; optimal excystation of E. revolutum occurred at pH 8.2 and was 70% after 60 min. The rate of excystation was very rapid in E. liei, reaching 91% at 30 min, and was less rapid in E. revolutum reaching 40% at 30 min.
