| ticks of australia. the species that infest domestic animals and humans. | the book australian ticks by f.h.s. roberts (1970) is a land-mark in australian tick biology. but it is time for a new and improved book on the ticks of australia. the present book has identification guides and accounts of the biology and diseases associated with the 16 species of ticks that may feed on domestic animals and humans in australia. these comprise five argasid (soft) ticks: argas persicus (poultry tick), argas robertsi (robert's bird tick), ornithodoros capensis (seabird soft tick), ... | 2014 | 24943801 |
| a new method for in vitro feeding of rhipicephalus australis (formerly rhipicephalus microplus) larvae: a valuable tool for tick vaccine development. | rhipicephalus microplus is a hard tick that has a major impact on cattle health in tropical and subtropical regions because it feeds on cattle and is implicated in the transmission of pathogens that cause diseases such as bovine anaplasmosis and babesiosis. presently, acaricides are used to control tick infestation but this is becoming increasingly less effective due to the emergence of tick strains that are resistant to one or more classes of acaricides. anti-tick vaccines are a promising alter ... | 2017 | 28335800 |
| a molecular survey of tick-borne pathogens from ticks collected in central queensland, australia. | central queensland (cq) is a large and isolated, low population density, remote tropical region of australia with a varied environment. the region has a diverse fauna and several species of ticks that feed upon that fauna. this study examined 518 individual ticks: 177 rhipicephalus sanguineus (brown dog tick), 123 haemaphysalis bancrofti (wallaby tick), 102 rhipicephalus australis (australian cattle tick), 47 amblyomma triguttatum (ornate kangaroo tick), 57 ixodes holocyclus (paralysis tick), 9 ... | 2018 | 29336689 |
| parasiticide resistance in flies, lice and ticks in new zealand and australia: mechanisms, prevalence and prevention. | this review outlines the history of parasiticide resistance in the principal ectoparasites of sheep and cattle in new zealand and australia, blowflies, buffalo fly (haematobia irritans exigua), sheep biting louse (bovicola ovis) and cattle ticks, and discusses recent changes in their response to insecticides and acaricides. mechanisms of resistance and evaluation methods are described, with ways in which insecticide resistance can be avoided or ameliorated also discussed. resistance in sheep blo ... | 2015 | 25185062 |
| a list of the 70 species of australian ticks; diagnostic guides to and species accounts of ixodes holocyclus (paralysis tick), ixodes cornuatus (southern paralysis tick) and rhipicephalus australis (australian cattle tick); and consideration of the place of australia in the evolution of ticks with comments on four controversial ideas. | seventy species of ticks are known from australia: 14 soft ticks (family argasidae) and 56 hard ticks (family ixodidae). sixteen of the 70 ticks in australia may feed on humans and domestic animals (barker and walker 2014). the other 54 species of ticks in australia feed only on wild mammals, reptiles and birds. at least 12 of the species of ticks in australian also occur in papua new guinea. we use an image-matching system much like the image-matching systems of field guides to birds and flower ... | 2014 | 25236960 |
| experimental efficacy of a vaccine against rhipicephalus australis. | despite several decades of chemical use the cattle tick, rhipicephalus australis, still represents an important threat for breeders of tick susceptible cattle under tropical conditions. the intense use of acaricides has lead to the development of multi-resistant strains of ticks and alternative means of control need to be developed to maintain control. a vaccine against ticks, based on the boophilus microplus bm86 protein, is one of the promising alternative means of tick control. in this invest ... | 2017 | 29110171 |
| evaluation of three adjuvants with respect to both adverse effects and the efficacy of antibody production to the bm86 protein. | cattle tick infestations remain an important burden for farmers in tropical area like in new caledonia. with the development of acaricide resistance, tick vaccines should be an attractive alternative to control ticks but their efficacy needs to be improved. in this study three adjuvants were studied in an experimental tick vaccine with a bm86 protein to assess their performance in terms of antibody productions and adverse reactions following vaccinations. the water-in-oil adjuvant isa 61 vg led ... | 2017 | 28752480 |
| bioinformatic prediction of g protein-coupled receptor encoding sequences from the transcriptome of the foreleg, including the haller's organ, of the cattle tick, rhipicephalus australis. | the cattle tick of australia, rhipicephalus australis, is a vector for microbial parasites that cause serious bovine diseases. the haller's organ, located in the tick's forelegs, is crucial for host detection and mating. to facilitate the development of new technologies for better control of this agricultural pest, we aimed to sequence and annotate the transcriptome of the r. australis forelegs and associated tissues, including the haller's organ. as g protein-coupled receptors (gpcrs) are an im ... | 2017 | 28231302 |
| repellent effects of melaleuca alternifolia (tea tree) oil against cattle tick larvae (rhipicephalus australis) when formulated as emulsions and in β-cyclodextrin inclusion complexes. | rhipicephalus australis (formerly boophilus microplus) is a one host tick responsible for major economic loss in tropical and subtropical cattle production enterprises. control is largely dependent on the application of acaricides but resistance has developed to most currently registered chemical groups. repellent compounds that prevent initial attachment of tick larvae offer a potential alternative to control with chemical toxicants. the repellent effects of melaleuca alternifolia oil (tto) emu ... | 2016 | 27369582 |
| the mitochondrial genome of a texas outbreak strain of the cattle tick, rhipicephalus (boophilus) microplus, derived from whole genome sequencing pacific biosciences and illumina reads. | the cattle fever tick, rhipicephalus (boophilus) microplus is one of the most significant medical veterinary pests in the world, vectoring several serious livestock diseases negatively impacting agricultural economies of tropical and subtropical countries around the world. in our study, we assembled the complete r. microplus mitochondrial genome from illumina and pac bio sequencing reads obtained from the ongoing r. microplus (deutsch strain from texas, usa) genome sequencing project. we compare ... | 2015 | 26117172 |
| reinstatement of rhipicephalus (boophilus) australis (acari: ixodidae) with redescription of the adult and larval stages. | rhipicephalus australis fuller, the australian cattle tick, is reinstated and the adults and larvae redescribed from material collected in australia. this long ignored boophilid was previously known as r. microplus canestrini for specimens reported in australia and new caledonia. the adults of r. australis are easily recognized by a combination of characters, such as the ventro-medial spurs in the palpal segments of the male, and the abundant, plumose, pale white setae on the dorsum of the femal ... | 2012 | 22897039 |
