Tick paralysis is the only tick-borne disease that is not caused by an infectious organism. The illness is caused by a neurotoxin produced in the tick’s salivary gland. The tick incoculates the host with a toxin from tick salivary glands during a blood meal. The toxin causes symptoms within a week beginning with weakness in both legs that progresses to paralysis. The paralysis ascends to the trunk, arms, and head within hours and may lead to respiratory failure and death. The disease can present as acute ataxia without muscle weakness.
Removal of the embedded tick usually results in resolution of symptoms within several hours to days. If the tick is not removed, the toxin can be fatal.
Please be aware that you dog can get this too. http://www.nutrecareblog.com/2011/05/tick-paralysis/
