Paralysis of domestic stock by the paralysis tick Ixodes holocyclus is chiefly a disease of young animals (especially calves) and of non-habituated stock introduced into tick-infested country in spring. These species have a global distribution with approx 60 Ethiopian spp., 56 palearctic spp., 24 neararctic spp., 33 neotropical spp., 22 oriental spp. The number of domestic animals affected annually by tick paralysis ranges from 10,000 to 100,000 with a death rate of approximately 10% (Atwell et al., 2001; Hall-Mendelin et al., 2011; Vink et al., 2014). Tick paralysis caused by the Australian paralysis tick, Ixodes holocyclus, is characterized by an ascending flaccid paralysis and, if not treated, death can occur within 24 to 48 hours of onset of clinical signs.

Rhipicephalus sanguineus. 1985, 1988). From three days following host attachment, the Australian paralysis tick, Ixodes holocyclus, secretes a neurotoxin that annually causes paralysis in approximately 10,000 domestic pets.Lotilaner, a novel isoxazoline formulated in a chewable flavoured tablet (Credelio TM), produces rapid onset of acaricidal activity in dogs, with an efficacy duration of at least one month. Some maps and references have suggested that it is found in such distant countries as Indonesia, Papua/New Guinea and even India.
