Diplopylidium spp

From Dog
Adult D. nolleri[1]

Diplopylidium are a parasitic small intestinal tapeworm of dogs and cats in southern Europe and the Middle East.

These cestodes have four suckers on the rostral end with a retractable rostrellum armed with thorn-like hooks. Proglottids are shaped like cucumber seeds. Paratenic hosts are thought to be coprophagous insects, and develop into larval cystercercoids in small reptiles. Dogs become infected by eating infected second intermediate hosts.

Species which have been reported in dogs include:

  • Diplopylidium nolleri[2]
  • Diplopylidium acanthotetra

No clinical signs have been reported in dogs. Co-infections with other intestinal parasites is very common[3].

Diagnosis is based on coprological identification of eggs.

Treatment is effective with praziquantel at 25 mg/kg every 4 - 6 weeks.
