| salmonella javiana infection in an infant associated with a marsupial, the quokka, setonix brachyurus, in western australia. | salmonella javiana, a serotype rarely isolated in australia, has been recovered from the faeces of a 14-month-old infant with symptoms of enteritis.the child had been closely associated with a marsupial species, the quokka, during a vacation on rottnest island in western australia, and s. javiana was isolated from faecal pellets from adult quokkas, and also from a snake collected on the island.sampling revealed a high incidence of salmonella infection in the quokkas. in all, 62 out of 87 animals ... | 1973 | 4518341 |

| identification of novel babesia and theileria genotypes in the endangered marsupials, the woylie (bettongia penicillata ogilbyi) and boodie (bettongia lesueur). | piroplasms, which include the genera theileria and babesia, are blood-borne parasites transmitted mainly by tick vectors. relatively little is known about their prevalence and clinical impact in australian marsupials. in the present study the occurrence and molecular phylogeny of these parasites were studied in both wild and captive marsupials from western australia (wa) and queensland (qld). blood samples were screened by microscopy and molecular methods, using pcr and dna sequencing of the 18s ... | 2012 | 22433913 |
| molecular characterization of native australian trypanosomes in quokka (setonix brachyurus) populations from western australia. | the quokka, setonix brachyurus, is a vulnerable, small marsupial endemic to western australia. blood samples were collected from quokkas from three different geographical locations; two peoples bay, bald island and rottnest island. the overall prevalence of trypanosomes by nested pcr at the 18s ribosomal rna gene was 57.3% (63/110) with prevalences of 91.4%, 85.3% and 4.9% respectively for two peoples bay, bald island and rottnest island. phylogenetic analysis conducted on 47 18s pcr positives i ... | 2016 | 26697991 |
| eimeria collieie n. sp. (apicomplexa:eimeriidae) from the western long-necked turtle (chelodina colliei). | a new species, eimeria collieie n. sp., is described from the western long-necked turtle (chelodina colliei). sporulated oocysts (n = 35) are spherical to subspherical, with colourless single layer oocyst wall, 0.6 ± 0.2 (0.4-0.7) µm thick. oocyst with elongated ellipsoid sporocysts. oocyst length, 29.8 ± 0.4 (28.2-31.0) µm; oocyst width, 29.4 ± 0.3 (28.0-30.8) µm; oocyst length/width (l/w) ratio, 1.0 ± 0.03 (1.0-1.05). micropyle, oocyst residuum and polar granule were absent. sporocysts with sp ... | 2015 | 25917644 |
| effect of available surface water on levels of antidiuretic hormone (lysine vasopressin) and water and electrolyte metabolism of the rottnest island quokka (setonix brachyurus). | a sensitive radioimmunoassay was developed to measure circulating levels of the neurohypophysial peptide lysine vasopressin (lvp) in the marsupial quokka (setonix brachyurus), which is abundant on rottnest island off the coast of western australia. animals from locations on the island where free water is completely absent were compared in midsummer with animals from sites where brackish water is available and utilized by the quokkas. in the animals from west end, where free water is absent, circ ... | 1990 | 2295426 |
| further characterisation of two eimeria species (eimeria quokka and eimeria setonicis) in quokkas (setonix brachyurus). | the identification and characterisation of novel eimeria species has largely been based on sporulated oocyst and sporocyst morphology, the host species and the geographical range. variation in the size and shape of eimeria oocysts across their host range however, make the identification and characterisation of novel species using traditional methodologies alone problematic. the use of molecular markers and phylogenetic analysis has greatly advanced our ability to characterise eimeria species and ... | 2014 | 24508502 |
