Adult Haemaphysalis tick

Hemaphysalis spp are a well recognised tick parasite of lagomorphs worldwide.

These skin parasites attach to the skin of lagomorphs, and as well as causing skin irritation, are responsible for blood loss (anemia) and transmission of various haemoplasms such as Rickettsia spp[1]

Pathogenic species identified in rabbits include:

  • Haemaphysalis leporispalustris[2]
  • Haemaphysalis longicornis[3]

Diagnosis is based on isolation and identification of this parasite under light microscopy.

Treatment is relatively effective with acaricides such as ivermectin.
