population structure of the peridomestic mosquito ochlerotatus notoscriptus in australia.ochlerotatus notoscriptus (skuse) (diptera: culicidae) is the predominant peridomestic mosquito in australia where it is the primary vector of dog heartworm, dirofilaria immitis (leidy), and a potentially important vector of arboviruses (barmah forest, ross river) with geographical variation of vector competence. although widespread, oc. notoscriptus has low dispersal ability, so it may have isolated subpopulations. the identification of gene flow barriers may assist in understanding arbovirus e ...200415189244
preliminary report on the northern australian melioidosis environmental surveillance project.an environmental surveillance programme was developed to determine whether water supplies could be a source of burkholderia pseudomallei as noted during previous melioidosis outbreak investigations. water supplies to communities in the three northern australian jurisdictions (western australia, northern territory and queensland) were sampled periodically during 2001 and 2002. water and soil samples were collected from communities known to have had recent culture-positive melioidosis cases and ne ...200415473143
dog health program in numbulwar, a remote aboriginal community in east arnhem land. 200616958628
detection of anaplasma platys and babesia canis vogeli and their impact on platelet numbers in free-roaming dogs associated with remote aboriginal communities in australia.to detect anaplasma platys and babesia canis vogeli infection, using polymerase chain reaction (pcr)-based assays, in free-roaming dogs associated with eight aboriginal communities in remote areas of australia and to determine the impact of infection through the assessment of platelet numbers.200616958629
cross-sectional study of canine leptospirosis in animal shelter populations in mainland australia.to measure the prevalence of canine leptospirosis in queensland and to detect infection, if present, in new south wales, victoria, south australia, western australia and the northern territory by measuring the serological titres of dogs held in animal shelters.200818673473
skin infections and infestations in aboriginal communities in northern australia.the most important skin infections in aboriginal communities in central and northern australia are scabies and streptococcal pyoderma. scabies is endemic in many remote aboriginal communities, with prevalences in children up to 50%. the cycles of scabies transmission underlie much of the pyoderma. up to 70% of children have skin sores, with group a streptococcus (gas) the major pathogen. group a streptococcus is responsible for the continuing outbreaks of post-streptococcal glomerulonephritis an ...200010954983
genetically distinct dog-derived and human-derived sarcoptes scabiei in scabies-endemic communities in northern australia.overcrowding is a significant factor contributing to endemic infection with sarcoptes scabiei in human and animal populations. however, since scabies mites from different host species are indistinguishable morphologically, it is unclear whether people can be infected from scabies-infested animals. molecular fingerprinting was done using three s. scabiei-specific single locus hypervariable microsatellite markers, with a combined total of 70 known alleles. multilocus analysis of 712 scabies mites ...199910548286
dirofilaria immitis in the dingo (canis familiaris dingo) in a tropical region of the northern territory, australia.the heart and lungs from 32 adult dingoes (canis familiaris dingo) were examined for canine heartworm (dirofilaria immitis) infection. eighteen of 32 (56%) samples were infected, with intensity of infection ranging from 1 to 31 worms per animal. seven of 18 (39%) infections were single sex infections. large numbers of circulating microfilariae were present in blood from all dingoes infected with both sexes of worms.19883352087
dna relatedness and biochemical features of campylobacter spp. isolated in central and south australia.investigations of the etiology of diarrhea in patients in south australia and the northern territory showed that campylobacter spp. other than campylobacter jejuni and c. coli were common in children. campylobacters which were hippurate positive, nitrate negative, and susceptible to cephalothin and polymyxins were shown to be closely related to c. jejuni by dna studies. thermotolerant catalase-negative campylobacters were also isolated. these were h2s negative and biochemically resembled the cat ...19852991331
oocysts and high seroprevalence of neospora caninum in dogs living in remote aboriginal communities and wild dogs in australia.canines are definitive hosts of neospora caninum (apicomplexa). for horizontal transmission from canines to occur, viable oocysts of n. caninum must occur in the environment of susceptible intermediate hosts. canids in australia include wild dogs and aboriginal community dogs. wild dogs are those dogs that are not dependent on humans for survival and consist of the dingo, feral domestic dog and their hybrid genotypes. aboriginal community dogs are dependent on humans, domesticated and owned by a ...201122245069
Molecular evidence of Rickettsia felis infection in dogs from Northern Territory, Australia.The prevalence of spotted fever group rickettsial infection in dogs from a remote indigenous community in the Northern Territory (NT) was determined using molecular tools. Blood samples collected from 130 dogs in the community of Maningrida were subjected to a spotted fever group (SFG)-specific PCR targeting the ompB gene followed by a Rickettsia felis-specific PCR targeting the gltA gene of R. felis. Rickettsia felis ompB and gltA genes were amplified from the blood of 3 dogs. This study is the ...201121989454
peruvian horse sickness virus and yunnan orbivirus, isolated from vertebrates and mosquitoes in peru and australia.during 1997, two new viruses were isolated from outbreaks of disease that occurred in horses, donkeys, cattle and sheep in peru. genome characterization showed that the virus isolated from horses (with neurological disorders, 78% fatality) belongs to a new species the peruvian horse sickness virus (phsv), within the genus orbivirus, family reoviridae. this represents the first isolation of phsv, which was subsequently also isolated during 1999, from diseased horses in the northern territory of a ...200919766284
genetic epidemiology of sarcoptes scabiei (acari: sarcoptidae) in northern australia.utilising three hypervariable microsatellite markers we have previously shown that scabies mites on people are genetically distinct from those on dogs in sympatric populations in northern australia. this had important ramifications on the formulation of public health control policies. in contrast phylogenetic analyses using mitochondrial markers on scabies mites infecting multiple animal hosts elsewhere in the world could not differentiate any genetic variation between mite haplotype and host sp ...200415157767
the mitochondrial 12s gene is a suitable marker of populations of sarcoptes scabiei from wombats, dogs and humans in australia.we sequenced part of the mitochondrial 12s ribosomal rna gene of 23 specimens of sarcoptes scabiei from eight wombats, one dog and three humans. twelve of the 326 nucleotide positions varied among these mites and there were nine haplotypes (sequences) that differed by 1-8 nucleotides. phylogenetic analyses indicated that these mites were from two lineages: (1) mites from wombats from victoria, australia, and mites from the humans and dog from the northern territory, australia (haplotypes 1-4, 9) ...200211999028
