Original Paper


The life cycle of Tylodelphys mashonense (Digenea: Diplostomidae), whose metacercariae occur in the cranial cavity of the widely cultivated catfish Clarias gariepinus, was resolved by the application of molecular markers. Both COI barcodes and ITS sequences obtained from diplostomid-like cercariae infecting Bulinus spp. from Mindu Dam, Morogoro, matched those acquired from metacercariae from the catfish C. gariepinus, and those from adult T. mashonense from the grey heron Ardea cinerea and the white egret Egretta alba. The success in linking the life cycle stages of T. mashonense using molecular tools highlights the usefulness of this approach in resolving the complex life cycles of digeneans in the absence of experimental establishment.
