Further information

Encephalitozoon cuniculi is a protozoal parasite of rabbits which affects the nervous and urinary systems and can cause a number of clinical signs. These include, but are not limited to, head tilt, hind limb paralysis or weakness, eye problems and death. It is a common parasite which is frequently sub-clinical, but in one study over 50% of rabbits in the UK were shown to have been infected. Encepalitozoon cuniculi may be passed on to humans and presents a potential risk to individuals who may have deficiencies to the immune system. Date of last review: May 2013
