| hematological and serum biochemical reference values and cohort analysis in the gilbert's potoroo (potorous gilbertii). | hematology and serum biochemistry blood values are tabulated for australia's most critically endangered mammal, the gilbert's potoroo (potorous gilbertii). significant differences were found between origin (captive or wild individuals) and age (subadult or adult) of animals. sex, and presence or absence of treponema infection, had minimal significance on blood values. typical cell morphology is discussed, and hemoparasite examination identified theileria spp. and breinlia spp. eighty samples wer ... | 2009 | 19569474 |
| sequence analyses at mitochondrial and nuclear loci reveal a novel theileria sp. and aid in the phylogenetic resolution of piroplasms from australian marsupials and ticks. | the order piroplasmida encompasses two main families: babesiidae and theileriidae, containing tick-borne pathogens of veterinary and medical importance worldwide. while only three genera (babesia, cytauxzoon and theileria) comprising piroplasm parasites are currently recognised, phylogenetic studies at the 18s rrna (18s) gene suggest that these organisms represent at least ten lineages, one of which comprises the relatively unique and highly diverse theileria spp. from australian marsupials and ... | 2019 | 31851687 |

| investigation of the morphological diversity of the potentially zoonotic trypanosoma copemani in quokkas and gilbert's potoroos. | trypanosomes are blood-borne parasites that can cause severe disease in both humans and animals, yet little is known of the pathogenicity and life-cycles of trypanosomes in native australian mammals. trypanosoma copemani is known to be infective to a variety of australian marsupials and has recently been shown to be potentially zoonotic as it is resistant to normal human serum. in the present study, in vivo and in vitro examination of blood and cultures from australian marsupials was conducted u ... | 2015 | 26160545 |
| 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 |
| Balanoposthitis, dyspareunia, and treponema in the critically endangered Gilbert's potoroo (Potorous gilbertii). | The Gilbert's potoroo (Potorous gilbertii) is one of Australia's most critically endangered mammals with a current estimated population of 70 individuals. Both the wild and captive populations have a long history of balanoposthitis with associated crusting, ulceration, and preputial discharge. We sought to identify the microbial species found in the discharge, determine their significance in causing balanoposthitis, and correlate these findings with reproductive success and survivorship. Bacteri ... | 2011 | 22102677 |
| vector of trypanosoma copemani identified as ixodes sp. | summarya total of 41 ticks were collected from 15 quokkas on bald island and 2 ticks from a gilbert's potoroo from two peoples bay. three species of ixodid ticks ixodes australiensis, ixodes hirsti and ixodes myrmecobii were identified on the quokkas known to have a high prevalence of trypanosoma copemani. tick faeces from ticks isolated from 8 individual quokkas and a gilbert's potoroo were examined with one identified as positive for trypanosomes. faecal examination revealed trypanosomes simil ... | 2011 | 21518469 |
| theileria gilberti n. sp. (apicomplexa: theileriidae) in the gilbert's potoroo (potorous gilbertii). | the morphology and genetic characterisation of a new species of piroplasm identified in the blood of the gilbert's potoroo (potorous gilbertii) from the two peoples bay nature reserve near albany, western australia, is described from blood and tissue samples from 16 gilbert's potoroos. microscopy of blood showed these parasites are highly pleomorphic with a mean length of 1.8 mum and mean width of 0.85 mum. phylogenetic analysis of 18s rrna sequence data identified the piroplasm as a new species ... | 2009 | 19527357 |
| morphological and molecular characterization of trypanosoma copemani n. sp. (trypanosomatidae) isolated from gilbert's potoroo ( potorous gilbertii) and quokka ( setonix brachyurus). | little is known of the prevalence and life-cycle of trypanosomes in mammals native to australia. native australian trypanosomes have previously been identified in marsupials in the eastern states of australia, with one recent report in brush-tailed bettongs (bettongia penicillata), or woylie in western australia in 2008. this study reports a novel trypanosoma sp. identified in blood smears, from 7 critically endangered gilbert's potoroos (potorous gilbertii) and 3 quokkas (setonix brachyurus) in ... | 2009 | 19416553 |
| cryptococcosis in gilbert's and long-nosed potoroo. | two cases of fatal cryptococcosis are described, one of cryptococcus neoformans infection in a gilbert's potoroo (potorous gilbertii) and one of cryptococcus gattii infection in a long-nosed potoroo (potorous tridactylus). the diagnoses were confirmed by culture and specific immunohistochemistry, respectively. the long-nosed potoroo tested positive using the latex cryptococcal antigen test (lcat), whereas the gilbert's potoroo had a negative lcat result despite having advanced disease of some du ... | 2007 | 18229862 |
| molecular phylogenetic relationships of two extinct potoroid marsupials, potorous platyops and caloprymnus campestris (potoroinae: marsupialia). | complete 12s rrna and partial cytochrome b (cytb) gene sequences have been obtained from museum samples of two recently extinct potoroids-potorous platyops and caloprymnus campestris. phylogenetic analyses based on these mitochondrial dna sequences suggest that the broad-faced potoroo (p. platyops) was a close relative of the recently discovered potorous longipes and the recently re-discovered potorous gilberti. although the extinct desert rat-kangaroo (c. campestris) was clearly resolved as a m ... | 2004 | 15062789 |
| hyperoxaluria, hyperglycoluria and renal oxalosis in gilbert's potoroos (potorous gilbertii). | six gilbert's potoroos (potorous gilbertii) in a captive colony, five of which were closely related, died or were euthanased with severe renal disease. clinical signs were mostly non-specific. renal calculi were seen on ultrasound of two affected potoroos and oxalate crystalluria was seen in two of three affected potoroos that had urine samples examined. necropsies revealed extensive severe renal oxalosis in all affected potoroos. these findings and markedly increased concentrations of glycolate ... | 2017 | 28653383 |
| monitoring reproduction in the critically endangered marsupial, gilbert's potoroo (potorous gilbertii): preliminary analysis of faecal oestradiol-17beta, cortisol and progestagens. | gilbert's potoroo (potorous gilbertii) was rediscovered in 1994 after having been presumed extinct for 120 years. estimates indicate fewer than 40 individuals remain at two peoples bay nature reserve on the south coast of western australia although a translocated population of approximately 20 animals has recently been established on nearby bald island. a captive breeding facility has been established adjacent to the mainland population but few young have been produced (8 since 1995). faecal lev ... | 2010 | 19539621 |
