Adult Apophallus intestinal fluke[1]

Apophallus spp are a non-pathogenic intestinal fluke parasite of dogs.

Pathogenic species in dogs include:

  • Apophallus donicum
  • Apophallus muehlingi[2]

The life cycle of this parasite includes snails as first intermediate hosts and fish (usually mullets; Mugil cephalus) as second intermediate host. Dogs become infected from eating fish that contain encysted metacercariae[3].

Diagnosis is based on coprological identification of Apophallus eggs[4].

Treatment of this parasite in dogs is relatively effective with praziquantel.
