Clinical Effects

Epidemiology

Habitat

  • Lives in hair coat of wild and domestic rabbits and hares.

Lifecycle

  • Egg → larva → 2 nymph stages → adult.
  • Eggs laid singly and attached to a hair by a short stalk.

Transmission

  • Rabbit → rabbit.

Pathological effects

  • Usually found in highest numbers along the dorsum and around the thighs.
  • Hypersensitivity reaction may occur leading to:

Other Host Effects

  • Usually commensal with no interaction.
  • Treatment rarely indicated.

Control

Control via chemotherapies

  • Ivermectin Ivermectin or doramectin Doramectin at 400 ug/kg SC, 3 injections at intervals of 2 weeks.
  • Treat all in-contact rabbits.
  • Topical selamectin Selamectin and topical imidacloprid Imidacloprid plus permethrin have been shown to eliminate L. gibbus infestation in laboratory rabbits. Selamectin alone resulted in a more rapid clinical resolution than the combination treatment.
