Genetic characterization of flea-derived Bartonella species from native animals in Australia suggests host-parasite co-evolution.Fleas are important arthropod vectors for a variety of diseases in veterinary and human medicine, and bacteria belonging to the genus Bartonella are among the organisms most commonly transmitted by these ectoparasites. Recently, a number of novel Bartonella species and novel species candidates have been reported in marsupial fleas in Australia. In the present study the genetic diversity of marsupial fleas was investigated; 10 species of fleas were collected from seven different marsupial and pla ...201121856444
in situ hybridization to detect bandicoot papillomatosis carcinomatosis virus type 1 in biopsies from endangered western barred bandicoots (perameles bougainville).the western barred bandicoot (perameles bougainville) is an endangered australian marsupial species in which a papillomatosis and carcinomatosis syndrome occurs. bandicoot papillomatosis carcinomatosis virus type 1 (bpcv1) is associated with the lesions of this progressively debilitating syndrome. five digoxigenin-labelled dna probes were generated for in situ hybridization (ish) and the technique was optimized and performed on formalin-fixed paraffin-embedded (ffpe) biopsies. staining of kerati ...200818198372
hematologic characteristics of captive western barred bandicoots (perameles bougainville) from western australia.the western barred bandicoot (perameles bougainville) is an australian marsupial species now considered endangered as a consequence of habitat destruction and predation. a recently discovered papillomatosis syndrome is hindering efforts to repopulate this species. hematology reference intervals have been lacking for p bougainville, preventing optimal interpretation of hematology results from wart-affected and clinically normal animals.200718041700
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.

One of 13 tick samples and 1 of 12 P. bougainville fecal samples were positive for C. burnetii DNA using quantitat ...201122167449
diversity of bartonella species detected in arthropod vectors from animals in australia.a variety of bartonella species were detected in two species of ticks and three species of fleas collected from marsupial hosts; brush-tailed bettong or woylie (bettongia penicillata) and western barred bandicoots (perameles bougainville) and from a rodent host; rattus fuscipes in western australia. bartonella species were detected using nested-pcr of the glta gene and the 16s-23s ribosomal internal transcribed spacer region (its), and species were characterized using dna sequencing of the 16s r ...201121862131
insights into polyomaviridae microrna function derived from study of the bandicoot papillomatosis carcinomatosis viruses.several different members of the polyomaviridae, including some human pathogens, encode micrornas (mirnas) that lie antisense with respect to the early gene products, the tumor (t) antigens. these mirnas negatively regulate t antigen expression by directing small interfering rna (sirna)-like cleavage of the early transcripts. mirna mutant viruses of some members of the polyomaviridae express increased levels of early proteins during lytic infection. however, the importance of mirna-mediated nega ...201121345962
cutaneous papillomatosis and carcinomatosis in the western barred bandicoot (perameles bougainville).a progressive wart-like syndrome in both captive and wild populations of the western barred bandicoot (wbb) is hindering conservation efforts to prevent the extinction of this endangered marsupial. in this study, 42 wbbs exhibiting the papillomatosis and carcinomatosis syndrome were examined. the disease was characterized by multicentric proliferative lesions involving cutaneous and mucosal surfaces, which were seen clinically to increase in size with time. grossly and histologically the smaller ...200818192585
a novel virus detected in papillomas and carcinomas of the endangered western barred bandicoot (perameles bougainville) exhibits genomic features of both the papillomaviridae and polyomaviridae.conservation efforts to prevent the extinction of the endangered western barred bandicoot (perameles bougainville) are currently hindered by a progressively debilitating cutaneous and mucocutaneous papillomatosis and carcinomatosis syndrome observed in captive and wild populations. in this study, we detected a novel virus, designated the bandicoot papillomatosis carcinomatosis virus type 1 (bpcv1), in lesional tissue from affected western barred bandicoots using multiply primed rolling-circle am ...200717898069
ocular chlamydiales infections of western barred bandicoots (perameles bougainville) in western australia.the western barred bandicoot (perameles bougainville) is an endangered species, free ranging on only two islands off the coast of western australia (dorre and bernier islands). conservation efforts are currently directed at reintroducing these marsupials into predator-proof enclosures and habitats in historical distribution ranges on the mainland in the southwest of western australia and in south australia. in september 2000, 19 western barred bandicoots were captured on bernier island for trans ...200517315464
molecular characterization of chlamydophila pneumoniae isolates from western barred bandicoots.chlamydophila pneumoniae is an obligate intracellular respiratory pathogen that has been associated with pneumonia and chronic bronchitis, atherosclerosis, asthma and other chronic diseases in humans. however, c. pneumoniae is not restricted to humans, as originally thought, and can cause infections in several animal hosts. c. pneumoniae was isolated in cell culture from nine western barred bandicoots (perameles bougainville) from australia. the sequences of five genomic regions were determined, ...200717314374
a new eimeria species parasitic in western barred bandicoots, perameles bougainville (marsupialia: peramelidae), in western australia.feces from western barred bandicoots, perameles bougainville, examined during routine monitoring of captive breeding colonies and wild populations were frequently found to contain oocysts. fecal oocysts from 1 individual housed at kanyana wildlife rehabilitation centre were allowed to sporulate in 2% potassium dichromate (k2cr2o7) at room temperature. sporulated oocysts are subspheroidal 18.8 x 17.9 (16.9-21.0 x 16.0-19.9) microm, with length/width (l/w) ratio of 1.05 (1.00-1.15), lack a micropy ...200617304809
