Linguatula serrata Infection in Lagomorphs

Summary Information
Diseases / List of Parasitic Diseases / Disease summary
Alternative Names Tongue worm
Disease Agents
  • Linguatula serrata (B614.11.w11)
Morphology
  • The Linguatula nymph found in rabbits has been described as a white, legless, "tongue-shaped", pseudoannulated parasite that is flattened ventrally and slightly convex dorsally, measuring five to six centimetres. (B614.11.w11)

Life cycle
  • Adult Linguatula serrata mites are found in the respiratory tract of the wolf, fox, dog, and more rarely the goat, sheep, and human. Eggs are expelled from the definitive host's respiratory tract and then ingested by the rabbit where they hatch into larvae. The larvae then puncture the bowel wall and enter the mesenteric lymph nodes where they develop into infective nymphs. Infection of the definitive host occurs when they ingest an affected rabbit.

General Description The natural intermediate host of linguatulid mites are wild rabbits (Oryctolagus cuniculus - European rabbit and Sylvilagus spp.) from many countries including the USA. (B614.11.w11)
Clinical signs
  • Clinical signs in rabbits are not likely to be produced by linguatulid mite infections. Incidental findings may be seen at post mortem. (B614.11.w11)
