Encephalitozoon cuniculi is an intracellular protozoan parasite which can cause a range of clinical signs including hind limb paresis, head tilt, collapse, urinary incontinence, cataract formation and lens-induced uveitis and death. Transmission is primarily via ingestion of spores shed in the urine contaminating food and/or water.
A 2006 UK study showed a seroprevalence of 52 % in domestic rabbits indicating the widespread nature of the parasite.
Panacur Rabbit is an aid in the control of E. cuniculi and it is recommended that additional preventative measures are taken such as ensuring that food and water are placed appropriately to prevent urine contamination.
E. cuniculi has zoonotic potential and infection has been reported in immunosuppressed people.
Treatment of E. cuniculi in Rabbits
Routine dosing of rabbits is recommended 2-4 times yearly.
Dosing should also be considered during periods of higher risk, such as when the rabbit is adopted, and when placing near or with other rabbits.
The following preventative treatment course of 20 mg fenbendazole/kg bodyweight is recommended:
9 days treatment 2 - 4 times yearly.
For rabbits with clinical signs associated with E.cuniculi the following treatment course of 20 mg fenbendazole/kg bodyweight is recommended:
28 days along with supportive nursing and vet care.
