Oncicola spp

From Dog
Oncicola canis adult acanthocephalan

Oncicola are a parasitic intestinal acanthocephalan which infect approximately 5% of stray dogs and cats throughout tropical and temperate countries worldwide.

Species which have been reported include:

  • Oncicola canis[1]
  • Omcicola pomatostomi[2]

This acanthocephalan utilises first and second intermediate hosts for transmission, including arthropods and rodents[3].

Few clinical signs are associated with this parasite, although concurrent parasitism with other worms may cause diarrhoea, vomiting, anorexia and weight loss[4].

Treatment is effective with fenbendazole or synthetic ivermectins such as selamectin.
