Parásitos

Encephalitozoonosis (E. cuniculi)

Infection with the parasite Encephalitozoon cuniculi, very common in rabbits. Many rabbits are carriers without symptoms; when it becomes active, it mainly affects the nervous system, the kidneys and the eyes.

Severe🐰 Rabbits Contagious Zoonosis

Symptoms to watch for

  • Head tilt (torticollis)
  • Loss of balance, rolling over
  • Abnormal eye movement
  • Tremors, paralysis of the hind legs
  • Cataracts, eye inflammation
  • Drinking and urinating a lot (kidney involvement)

Causes

A microscopic parasite spread through the urine of infected rabbits. Very widespread: a large proportion of rabbits are carriers. Stress and a drop in immune defences activate the disease.

Diagnosis

Blood test (serology) plus clinical signs. A definitive diagnosis is difficult because many healthy rabbits carry antibodies.

Treatment

A specific antiparasitic (fenbendazole) for several weeks, anti-inflammatories and supportive care. The sooner the neurological episode is treated, the better. Some rabbits are left with a permanent slight head tilt.

Prevention

Reduce stress, maintain good hygiene and quarantine new rabbits. It is a low-risk zoonosis, important for immunocompromised people.

When should you see the vet?

See an exotics vet as soon as possible if your rabbit tilts its head, loses its balance or rolls over.
