Tick paralysis: development of a vaccine.
The paralysis tick of Australia, Ixodes holocyclus, causes a severe toxicosis in domestic animals such as dogs and cats, livestock, and in some cases, humans. It is characterised by a rapidly ascending flaccid paralysis. The causative agent of the toxicosis is a neurotoxin(s) produced in the tick salivary glands. The current treatment for tick paralysis is in the form of a polyclonal dog antiserum. This antiserum treatment is expensive and effective only in the early stages of paralysis. The aim of current research is to develop a recombinant veterinary vaccine based on the tick neurotoxin peptide sequence. A successful vaccine would provide cost-effective, long-term protective immunity against tick-induced paralysis.
