| comparative analyses by hplc and the sodium channel and saxiphilin 3h-saxitoxin receptor assays for paralytic shellfish toxins in crustaceans and molluscs from tropical north west australia. | the increased frequency and distribution of red tides requires the development of high-throughput detection methods for paralytic shellfish toxins (pst). community ethics also requires that there be a reduced reliance upon the standard mouse bioassay. a biomolecular assay such as the sodium channel 3h-saxitoxin binding assay can satisfy both of these requirements but may be compromised by cross-reactivity with the structurally unrelated tetrodotoxins (ttx). this study utilised the sodium channel ... | 1998 | 9620576 |
| genetically determined resistance to flavivirus infection in wild mus musculus domesticus and other taxonomic groups in the genus mus. | inherited resistance to flaviviruses in laboratory mice is a rare trait conferred by an autosomal dominant gene (flvr). to provide information on genetic resistance to flaviviruses in wild mice, we analysed (i) wild m. m. domesticus trapped in australia, and (ii) mice representing other species and subspecies in the genus mus. mice were screened for resistance relative to c3h/hej mice by intracerebral challenge with murray valley encephalitis virus or yellow fever virus, and breeding studies wer ... | 1998 | 9638142 |
| murine viruses in an island population of introduced house mice and endemic short-tailed mice in western australia. | house mice (mus domesticus) were recently introduced to thevenard island, off the northwest coast of western australia. this island is also habitat for an endangered native rodent, the short-tailed mouse (leggadina lakedownensis). concerns have been raised that house mice may pose a threat to l. lakedownensis both through competition and as a source of infection. to assess the threat to l. lakedownensis posed by viral pathogens from m. domesticus, a serological survey was conducted from 1994 to ... | 1999 | 10231757 |
| water and sodium requirements of field populations of house mice (mus domesticus) and short-tailed mice (leggadina lakedownensis) on thevenard island, in the arid pilbara region of western australia. | the coexistence of the lakeland downs short-tailed mouse leggadina lakedownensis and house mouse mus domesticus on thevenard island, in the arid north of western australia, prompted a study to compare their seasonal water and sodium metabolism using tritiated water and sodium-22 as tracers. fractional water influx rates for m. domesticus (40.3 +/- 1.6% total body-water day-1) were significantly higher than those for l. lakedownensis (25.3 +/- 1.2% total body-water day-1). water effluxes were hig ... | 1999 | 10549142 |
| preliminary evidence of toxicity associated with the benthic cyanobacterium phormidium in south australia. | in april 2000, the water supply for yorke peninsula in south australia was deemed non-potable when extracts from a proliferation of the benthic cyanobacterium phormidium aff. formosum in upper paskeville reservoir were found to be lethally toxic by intraperitoneal injection into mice (400 mg kg-1). routine water quality monitoring had failed to detect the development of the phormidium until complaints of musty taste and odour, attributable to the production of 2-methyl-isoborneol (mib), were rec ... | 2001 | 11769248 |
| pathogens of house mice on arid boullanger island and subantarctic macquarie island, australia. | studies on island populations of house mice (mus domesticus) and their viruses reveal insights into viral persistence in isolated communities. we surveyed the ectoparasites, endoparasites, and antiviral antibodies for 11 murine viruses and two bacteria of house mice inhabiting two islands off australia. house mice on boullanger island were seropositive to two viruses, murine cytomegalovirus and epizootic diarrhea of infant mice. on subantarctic macquarie island, house mice were seropositive for ... | 2003 | 14733270 |
| cryptosporidium muris infection in bilbies (macrotis lagotis). | cryptosporidiosis is an enteric disease of animals and humans that can be fatal in immunocompromised individuals. there is no known effective treatment for cryptosporidiosis. bilbies are threatened marsupials and are bred in captivity as part of a recovery program to re-introduce this species to the southwest of western australia. cryptosporidium muris infection was detected in the faeces of bilbies at a captive breeding colony. stress associated with a high density of bilbies in enclosures may ... | 2003 | 15080483 |
| transmission of two australian strains of murine cytomegalovirus (mcmv) in enclosure populations of house mice (mus domesticus). | to control plagues of free-living mice (mus domesticus) in australia, a recombinant murine cytomegalovirus (mcmv) expressing fertility proteins is being developed as an immunocontraceptive agent. real-time quantitative pcr was used to monitor the transmission of two genetically variable field strains of mcmv through mouse populations after 25% of founding mice were infected with the n1 strain, followed by the g4 strain 6 weeks later. pathogen-free wild-derived mice were released into outdoor enc ... | 2005 | 16050517 |
| hypothermia versus torpor in response to cold stress in the native australian mouse pseudomys hermannsburgensis and the introduced house mouse mus musculus. | this study compared torpor as a response to food deprivation and low ambient temperature for the introduced house mouse (mus musculus) and the australian endemic sandy inland mouse (pseudomys hermannsburgensis). the house mouse (mass 13.0+/-0.48 g) had a normothermic body temperature of 34.0+/-0.20 degrees c at ambient temperatures from 5 degrees c to 30 degrees c and a basal metabolic rate at 30 degrees c of 2.29+/-0.07 ml o2 g(-1) h(-1). it used torpor with spontaneous arousal at low ambient t ... | 2007 | 17826203 |
| evaluation of the anti-inflammatory properties of dodonaea polyandra, a kaanju traditional medicine. | extracts of the medicinal plant species dodonaea polyandra were investigated as part of a collegial research partnership between northern kaanju traditional owners represented by chuulangun aboriginal corporation (centred on the wenlock and pascoe rivers, cape york peninsula, queensland, australia) and university-based researchers. d. polyandra, known as "uncha" in kaanju language, is used in northern kaanju traditional medicine for relief from pain associated with toothache and related ailments ... | 2010 | 20633620 |
