host-seeking behaviour by australian ticks (acari: ixodidae) with differing host specificities.	ticks generally detach from their hosts into sites where they are later exposed to host species which may or may not be suitable for infestation. the question of how four species of ixodid ticks, with differing specificities, behave towards such potential host species was examined. observations of the generalists, aponomma hydrosauri and amblyomma limbatum and the specialists, aponomma fimbriatum and aponomma concolor, showed that the generalists were attracted to a wider range of potential host ...	1995	7641569
aponomma (bothriocroton) glebopalma, n. subgen., n. sp., and amblyomma glauerti n. sp. (acari: ixodida: ixodidae), parasites of monitor lizards (varanidae) in australia.	aponomma (bothriocroton) glebopalma, n. subgen., n. sp., and amblyomma glauerti, n. sp. (acari: ixodidae), are described from the monitor lizards varanus glebopalma mitchell and varanus glauerti mertens in western australia and the northern territory, australia. the new subgenus is erected to accomodate a. (bothriocroton) glebopalma, a new species with a deeply pitted and pilose scutum in both the adult and immature stages, unlike all other described species of aponomma. this new species is foun ...	1994	8158616
evidence for the presence of francisella and spotted fever group rickettsia dna in the tick amblyomma fimbriatum (acari: ixodidae), northern territory, australia.	ticks (n = 252) were collected from five wild-caught reptile species during routine trapping in the djukbinj national park and fogg dam reserve, northern territory, australia. pooling of ticks (one to four ticks per pool), according to sex or host animal, resulted in 187 samples used for screening for the presence of rickettsia species via molecular methods. rickettsia dna was detected via the amplification of the glta, ompa, and ompb genes in 57 (34%) of the 187 tick samples, all of which conta ...	2009	19645299
phylogenetic analysis of ticks (acari: ixodida) using mitochondrial genomes and nuclear rrna genes indicates that the genus amblyomma is polyphyletic.	our understanding of the phylogenetic relationships among tick lineages has been limited by the lack of resolution provided by the most commonly used phylogenetic markers. mitochondrial genomes are increasingly used to address controversial phylogenetic relationships. to date, the complete mitochondrial genomes of eleven tick species have been sequenced; however, only three of these species are metastriate ticks, the most speciose lineage of ticks. in this study, we present the nucleotide sequen ...	2012	22465402
complete mitochondrial genome sequence data provides genetic evidence that the brown dog tick rhipicephalus sanguineus (acari: ixodidae) represents a species complex.	ticks are blood-sucking ectoparasites of great medical and veterinary significance that can transmit bacteria, protozoa, fungi and viruses, and cause a variety of human and animal diseases worldwide. in the present study, we sequenced the complete mitochondrial (mt) genome of rhipicephalus sanguineus from china (rsc) and compared with that of r. sanguineus from usa (rsu). nucleotide sequence difference in the full mt genome was 11.23% between rsc and rsu. for the 13 protein-coding genes, compari ...	2013	23630448
detection of theileria orientalis genotypes in haemaphysalis longicornis ticks from southern australia.	theileria are blood-borne intracellular protozoal parasites belonging to the phylum apicomplexa. previously considered a benign parasite in australia, outbreaks of clinical disease resulting from theileria orientalis genotypes have been reported in australia since 2006. since this time, outbreaks have become widespread in south-eastern australia, resulting in significant adverse impacts on local dairy and beef industries. this paper provides the first investigation into the possible biological a ...	2015	25889204
bacteria associated with amblyomma cajennense tick eggs.	ticks represent a large group of pathogen vectors that blood feed on a diversity of hosts. in the americas, the ixodidae ticks amblyomma cajennense are responsible for severe impact on livestock and public health. in the present work, we present the isolation and molecular identification of a group of culturable bacteria associated with a. cajennense eggs from females sampled in distinct geographical sites in southeastern brazil. additional comparative analysis of the culturable bacteria from an ...	2015	26537602
systematic revision of the adeleid haemogregarines, with creation of bartazoon n. g., reassignment of hepatozoon argantis garnham, 1954 to hemolivia, and molecular data on hemolivia stellata.	life cycles and molecular data for terrestrial haemogregarines are reviewed in this article. collection material was re-examined: hepatozoon argantis garnham, 1954 in argas brumpti was reassigned to hemolivia as hemolivia argantis (garnham, 1954) n. comb.; parasite dna was extracted from a tick crush on smear of an archived slide of hemolivia stellata in amblyomma rotondatum, then the 18s ssrrna gene was amplified by pcr. a systematic revision of the group is proposed, based on biological life c ...	2015	26551414
rickettsia detected in the reptile tick bothriocroton hydrosauri from the lizard tiliqua rugosa in south australia.	rickettsiosis is a potentially fatal tick borne disease. it is caused by the obligate intracellular bacteria rickettsia, which is transferred to humans through salivary excretions of ticks during the biting process. globally, the incidence of tick-borne diseases is increasing; as such, there is a need for a greater understanding of tick-host interactions to create more informed risk management strategies. flinders island spotted fever rickettsioses has been identified throughout australia (tasma ...	2016	27338482
