Adult P. complexus[1]

Parametorchis spp are a parasitic trematode of dogs in Asian countries.

Species which are apthogenic to dogs include:

  • Parametorchis complexus

These trematodes rely on two intermediate hosts (snails and marine fish[2]). Metacercaria are ingested by dogs, which migrate up the bile and pancreatic ducts, where they lay eggs[3].

Clinical signs in dogs include acute hepatitis and pancreatitis.

Diagnosis is based on identification of eggs in feces using ethyl acetate sedimentation.

A differential diagnosis would include other hepatic and bile duct flukes such as Opisthorchis spp, Metorchis spp and Clonorchis spp.

Treatment is effective with praziquantel.
