Abstract

Isolated viable metacercariae were collected from a heavly and moderately infected Schilbe mystis at Sohag province. These metacercarial cysts were submitted to prove the viability and the infective power. Constant number of viable metacercariae were fed to one week old squabs. The recovery rate was 6.75%. The digenetic trematode recovered from the intestinal mucosa two weeks post infection is Prohemistomum vivax, SONSINO, 1892.
