Paralysis of a dromedary camel caused by Hyalomma dromedarii infestation

A heavy tick infestation is reported, causing paralysis in an old female dromedary camel with all stages of Hyalomma dromedarii. The diagnosis relied solely on clinical signs due to a lack of specific methods for identifying tick neurotoxin(s). No gross or microscopic lesions were observed except for mild to marked demyelination of the spinal cord white matter.
