| range expansion of the tick amblyomma triguttatum triguttatum, an australian vector of q fever. | the tick amblyomma triguttatum triguttatum has previously been reported from western australia, queensland and new south wales. a viable population of this species, including all developmental stages, has now been discovered on the southern end of yorke peninsula, south australia. species determination was carried out morphologically and using 18s and 16s rrna. the data for 16s rrna are the first published for this species. amblyomma t. triguttatum is significant through its involvement in the n ... | 2000 | 10899523 |
| hosts of the exotic ornate kangaroo tick, amblyomma triguttatum triguttatum koch, on southern yorke peninsula, south australia. | amblyomma triguttatum triguttatum is assumed to be endemic to south-western western australia (including barrow island), queensland (excluding cape york peninsula), and new south wales, south to dubbo and barham. the species has been recorded on a range of mammalian hosts including macropods and domestic animals. in queensland, a. triguttatum triguttatum is implicated in the epidemiology of q fever. in 2000, the species was detected on southern yorke peninsula in south australia. we aimed to ide ... | 2007 | 17611781 |
| rickettsioses in australia. | the rickettsial diseases of australia are described in their chronological order of discovery. the include epidemic typhus (r. prowazekii); murine typhus (r. typhi) found australia-wide; scrub typhus (o. tsutsugamushi) only in tropical, northen australia; q. fever (c. burnetti) found australia-wide; queensland tick typhus (r. australis) along the east coast of australia; flinders island spotted fever (r. honei) in southeast australia; variant flinders island spotted fever (r. honei, strain "marm ... | 2009 | 19538275 |
| a survey of western australian sheep, cattle and kangaroos to determine the prevalence of coxiella burnetii. | the objective of this study was to investigate the prevalence of coxiella burnetii in two domestic ruminant species (cattle and sheep) and the western grey kangaroo (macropus fuliginosus) in western australia (wa). the idexx chekit q fever elisa and cft were used to test sera from 50 sheep and 329 head of cattle for anti-c. burnetii antibodies and 343 kangaroo sera were tested using an indirect elisa developed specifically for this study. faecal or urine samples collected from the same animals w ... | 2010 | 20036083 |
| Coxiella burnetii in Western Barred Bandicoots (Perameles bougainville) from Bernier and Dorre Islands in Western Australia. | The aim of this work is to investigate the presence of Coxiella burnetii in Perameles bougainville and their ticks on two islands off Western Australia. Haemaphysalis humerosa, Haemaphysalis ratti, and Haemaphysalis lagostrophi were collected from P. bougainville on Bernier and Dorre Islands from 2005 to 2007; only Amblyomma limbatum was collected from humans over the same interval. One of 13 tick samples and 1 of 12 P. bougainville fecal samples were positive for C. burnetii DNA using quantitat ... | 2011 | 22167449 |
| Prevalence of Coxiella burnetii in western grey kangaroos (Macropus fuliginosus) in Western Australia. | We investigated the role of the western grey kangaroo (Macropus fuliginosus) in the maintenance and transmission of Coxiella burnetii in Western Australia. Sera from 1,017 kangaroos were tested using an indirect enzyme-linked immunosorbent assay (ELISA) for the presence of C. burnetii antibodies. The overall antibody prevalence across 12 locations throughout mid- to southwestern Western Australia was 24.1% (95% CI: 21.6-26.8). Feces from 990 of the same animals were tested using PCR to identify ... | 2011 | 22102652 |
| determination of coxiella burnetii seroprevalence in macropods in australia. | many animal species, including macropods, have the potential to act as atypical reservoirs of the causative agent of q fever, coxiella burnetii. the objective of this study was to determine the seroprevalence of c. burnetii in various macropod species in australia. competitive and indirect elisas were developed for the testing of macropod sera for antibodies to phase ii and i c. burnetii antigens separately. a total of 500 macropod serum samples from selected species sampled in eastern and weste ... | 2011 | 21925808 |
| tick-borne infectious diseases in australia. | tick bites in australia can lead to a variety of illnesses in patients. these include infection, allergies, paralysis, autoimmune disease, post-infection fatigue and australian multisystem disorder. rickettsial (rickettsia spp.) infections (queensland tick typhus, flinders island spotted fever and australian spotted fever) and q fever (coxiella burnetii) are the only systemic bacterial infections that are known to be transmitted by tick bites in australia. three species of local ticks transmit b ... | 2017 | 28403767 |
| prevalence of markers of q fever exposure in the kimberley, western australia. | although a large pastoral industry exists in the kimberley region of western australia, there is no previously published information about the prevalence of immune markers for q fever exposure in this region's population. this paper identifies the prevalence of, and factors associated with, positive immune markers of q fever, and reports the uptake of q fever vaccination by eligible subjects in the kimberley region of western australia. data regarding q fever risk-factors were obtained using a s ... | 2003 | 12926742 |
