Holocyclotoxin-1, a cystine knot toxin from Ixodes holocyclus
Toxicon, 2014In the past 100 years minimal venom research has focused on ticks despite several species possessing a highly paralytic and lethal venom cocktail of proteinaceous molecules. The saliva of the Australian paralysis tick, Ixodes holocyclus, has been responsible for 20 human fatalities from 1900 to 1945, and up to 100,000 domestic animal fatalities ...

PARALYSIS OF CALVES BY THE TICK, IXODES HOLOCYCLUS
Australian Veterinary Journal, 1977Adult female Ixodes holocyclus were collected from the field at Fig Tree Pocket, a Brisbane suburb, at Tamborine Mountain, Queensland and at Lismore, New South Wales, in November 1974. Females were also reared from engorged nymphs collected off bandicoots from Tamborine Mountain July 1974 and 1975.

Suspected tick paralysis (Ixodes holocyclus) in a Miniature Horse
Australian Veterinary Journal, 2012A 9‐year‐old Miniature Horse gelding infested with ticks (Ixodes holocyclus) was presented with flaccid motor paralysis causing recumbency. Neurological examination and other diagnostic tests did not identify an alternative aetiology, leading to a presumptive diagnosis of tick paralysis.

CATTLE AND THE PARALYSIS TICK IXODES HOLOCYCLUS
Australian Veterinary Journal, 1975Paralysis 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. The tick has a wide host range, but its principal hosts are bandicoots.

Isolation of tick paralysis toxin from Ixodes Holocyclus
Toxicon, 1966The preparation of an extract from homogenates of replete Ixodes holocyclus is described. Chromatography of this extract was carried out on DEAE cellulose columns equilibrated with 0·025 M ammonium acetate buffer, pH 7·0–7·1. Batch-wise elution with 0·025, 0·1 and 0·25 M ammonium acetate buffers, pH 7·0–7·1 separated three fractions.

Ticks from mainland Australia (Victoria, New South Wales and Queensland) and Tasmania, identified morphologically as either Ixodes holocyclus or Ixodes cornuatus, were compared genetically using 24 enzyme loci. The results showed that ticks from three localities in Victoria were genetically similar to I. cornuatus in Tasmania, but both groups had fixed

Paralysis of cattle by Ixodes holocyclus Neumann
Australian Journal of Agricultural Research, 1975The number of engorging female Ixodes holocyclus needed to induce paralysis in young cattle was investigated. One or two females were insufficient to paralyse 2–3-week-old unexposed calves but 10 caused paralysis. Older unexposed calves weighing 80-160 kg were not paralysed by up to nine females whereas 20 caused paralysis.

Infestation in the dog by the paralysis tick, Ixodes holocyclus — 5. Treatment
Australian Veterinary Journal, 1988SUMMARY: In this study the value of drugs administered with hyperimmune serum in the treatment of advanced disease produced by Ixodes holocyclus was compared under controlled conditions. All control dogs died rapidly whereas one dog survived and 3 dogs died after receiving hyperimmune serum alone.
