Infection with which parasite is associated with head tilt and ataxia in rabbits?

Infection with Encephalitozoon cuniculi is notably linked to neurological symptoms in rabbits, such as head tilt and ataxia. This microsporidian parasite primarily affects the nervous system and kidneys of rabbits. When rabbits are infected, the parasite can cause lesions within the brain, leading to an inflammatory response that manifests as neurological issues, including coordination problems (ataxia) and abnormal head positioning (head tilt).

This condition is particularly concerning in rabbits, as it can result in significant morbidity. The presence of Encephalitozoon cuniculi in rabbits is often diagnosed through clinical signs, serological testing, and sometimes post-mortem examination. Early identification and management are crucial for the health of affected rabbits.

In contrast, the other parasites listed do not typically cause these specific neurological symptoms in rabbits; they affect different aspects of health and may lead to different clinical presentations. Understanding the specific association between Encephalitozoon cuniculi and neurological symptoms helps in the effective diagnosis and treatment of infected rabbits.
