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 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.

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

Infestation in the dog by the paralysis tick Ixodes holocyclus 3. Respiratory effects
Australian Veterinary Journal, 1987To assess respiratory function in dogs with tick paralysis, respiratory measurements were recorded on 14 dogs experimentally infested with Ixodes holocyclus. There was a progressive fall in respiratory rate with no change in tidal volume, which resulted in a significant fall in minute respiratory volume in the latter stages of the disease.

Infestation in the dog by the paralysis tick, Ixodes holocyclus — 4. Cardiovascular effects
Australian Veterinary Journal, 1988SUMMARY: To determine the extent and signficance of changes in heart rate and rhythm noticed previously in dogs paralysed with Ixodes holocyclus, two studies were undertaken. In one the electrocardiogram was recorded at stages throughout the disease and the traces analysed for changes, while in the second a detailed study of the effect of Ixodes ...

Factors influencing the toxicity of salivary gland extracts of Ixodes holocyclus Neumann
International Journal for Parasitology, 1978Abstract A bioassay using mice was developed to compare the toxin content of extracts of salivary glands of I. holocyclus at various stages of feeding. The quantity of toxin increased rapidly from the third day of feeding. Toxin production continued and increased in ticks removed after 3–5 days on mice and held at 30°C at 92% RH for 24 h, whereas no ...

Reproductive biology of Ixodes holocyclus
Laboratory and field investigations were carried out to obtain new information on the biology of Ixodes holocyclus. The bionomics of I.holocyclus were explored using additional and more detailed environmental regimes than previous workers. The speed of development increased with increasing temperatures for the parameters examined.openaire +2 more sources
Journal of Immunological Methods, 1990
The blocking conditions appropriate for Western blot identification of allergens of the Australian paralysis tick, Ixodes holocyclus, have been investigated. The results suggest that human serum is a potent blocking agent which may have wide application in the immunodetection of antigens.
