| serodiagnosis of acute toxoplasmosis in macropods. | the sera of 34 australian macropods, the brains of which had been bioassayed for toxoplasma gondii, were used to establish that a titre greater than 1/32 was significant for a direct agglutination test against toxoplasmosis. in addition, the concentration of 2-mercaptoethanol required to destroy the igm fraction of macropod serum was confirmed in a modified direct agglutination test. to further validate the tests, the serological responses of three eastern grey kangaroos (macropus giganteus) dos ... | 1989 | 2588468 |
| isolation, partial sequence and asynchronous appearance during lactation of lysozyme and alpha-lactalbumin in the milk of a marsupial, the common ringtail possum (pseudocheirus peregrinus). | 1. lysozyme and alpha-lactalbumin from the milk of the common ringtail possum have been purified and partially sequenced. 2. the lysozyme had similar enzymic activity to the c-type lysozyme of the domestic hen and 43% homology over the n-terminal 49 residues. 3. alpha-lactalbumin was present in the milk in two biologically active forms; the more acidic form had 66% sequence homology with the n-terminal 35 residues of red-necked wallaby, 54% with human and 43% with bovine alpha-lactalbumin. 4. sd ... | 1989 | 2605916 |
| observations on the treatment of necrobacillosis in wallabies. | clinical experience of 73 cases of necrobacillosis in red-necked wallabies (macropus rufogriseus) over a 6-year period is reviewed. diagnostic methods and the medical and surgical treatment options are detailed. it is suggested that survival curves are necessary to assess the outcome of treatment. | 1989 | 2775989 |
| pharmacokinetics of oxytetracycline in clinical cases in the red-necked wallaby (macropus rufogriseus). | oxytetracycline, administered at 40 mg kg-1 by intravenous injection, was used as part of the treatment of three female red-necked wallabies, macropus rufogriseus, with suspected fusobacterium necrophorum infections. the plasma concentrations of this drug in blood samples collected at intervals up to 24 hours after administration were measured using a biological assay. the pattern of decline in plasma oxytetracycline concentration with time was consistent with a two-compartment model. the half-l ... | 1988 | 3406529 |
| prevalence of toxoplasma gondii antibody in wild macropods. | an enzyme-linked immunosorbent assay (elisa) was developed to measure total antibody to toxoplasma gondii in serum samples from macropods. the validity of the assay was established by comparing parasite isolation in mice for 17 tasmanian pademelons (thylogale billardierii) and 17 bennett's wallabies (macropus rufogriseus rufogriseus). the elisa was then used to detect antibody against t. gondii in serum from 236 macropods, collected from 21 locations in tasmania, including flinders island. antib ... | 1988 | 3421883 |
| susceptibility of wallabies to fusobacterium necrophorum. | wallabies (macropus rufogriseus) were not appreciably more susceptible than rabbits or mice to fusobacterium necrophorum, a fact established by the subcutaneous injection of a series of graded doses into animals of each species. the strikingly frequent occurrence of necrobacillosis in captive macropods is therefore not due to a uniquely high susceptibility. a vaccine containing inactivated f necrophorum culture emulsified with freund's complete adjuvant failed to increase the resistance of walla ... | 1986 | 3739178 |
| provisional mapping of the gene for a cell surface marker, ga-1, in the red-necked wallaby macropus rufogriseus. | a series of m. rufogriseus-mouse somatic cell hybrids was constructed and analysed cytologically, enzymatically and immunologically. a monoclonal antibody, ga-1, was prepared against an m. rufogriseus cell surface antigen on an m. rufogriseus-mouse somatic cell hybrid. a gene determining the expression of this antigen was provisionally assigned to the long arm of the m. rufogriseus chromosome 3. the monoclonal antibody also reacted with an m. rufus (red kangaroo)-mouse somatic cell hybrid contai ... | 1985 | 3834888 |

| dietary partitioning of australia's two marsupial hypercarnivores, the tasmanian devil and the spotted-tailed quoll, across their shared distributional range. | australia's native marsupial fauna has just two primarily flesh-eating 'hypercarnivores', the tasmanian devil (sarcophilus harrisii) and the spotted-tailed quoll (dasyurus maculatus) which coexist only on the island of tasmania. devil populations are currently declining due to a fatal transmissible cancer. our aim was to analyse the diet of both species across their range in tasmania, as a basis for understanding how devil decline might affect the abundance and distribution of quolls through rel ... | 2017 | 29176811 |
| comparative nmr studies of diffusional water permeability of red blood cells from different species: xv. agile wallaby (macropus agilis), red-necked wallaby (macropus rufogriseus) and goodfellow's tree kangaroo (dendrolagus goodfellowi). | the water diffusional permeability (p(d)) of red blood cells (rbc) from agile wallaby (macropus agilis), red-necked wallaby (macropus rufogriseus) and goodfellow's tree kangaroo (dendrolagus goodfellowi) was monitored using an mn(2+)-doping (1)h nuclear magnetic resonance (nmr) technique at 400 mhz. the p(d) (cm s(-1)) values of agile wallaby rbcs were 7.5 x 10(-3) at 25 degrees c, 9 x 10(-3) at 30 degrees c, 11 x 10(-3) at 37 degrees c, and 13 x 10(-3) at 42 degrees c. the inhibitory effect of ... | 2009 | 19463965 |
| seroprevalence of retrovirus in north american captive macropodidae. | laboratory records of serology results from captive macropodidae sampled between 1997 and 2005 were reviewed to assess the seroprevalence of retrovirus exposure. serum samples from 269 individuals (136 males, 133 females) representing 10 species of macropods housed in 31 north american captive collections were analyzed for retrovirus antibody using an indirect immunofluorescent assay. the prevalence of positive antibody titers comparing male versus female, between species, between age groups, an ... | 2008 | 18816994 |
| reproductive disorders of marsupials. | marsupial reproduction differs significantly in anatomy and physiology from that of placental mammals. the gastrointestinal and urogenital tracts empty into a cloaca. reproductive parameters include gestation and pouch time, as the fetus develops outside of the uterus. captive marsupials discussed include sugar gliders), short-tailed opossums, virginia opossums, and tammar and bennett's wallabies. common disease conditions include joey eviction, pouch infections, mastitis, metritis, prostatitis, ... | 2017 | 28169182 |
| immunome database for marsupials and monotremes. | to understand the evolutionary origins of our own immune system, we need to characterise the immune system of our distant relatives, the marsupials and monotremes. the recent sequencing of the genomes of two marsupials (opossum and tammar wallaby) and a monotreme (platypus) provides an opportunity to characterise the immune gene repertoires of these model organisms. this was required as many genes involved in immunity evolve rapidly and fail to be detected by automated gene annotation pipelines. | 2011 | 21854560 |
| genomic instability within centromeres of interspecific marsupial hybrids. | several lines of evidence suggest that, within a lineage, particular genomic regions are subject to instability that can lead to specific types of chromosome rearrangements important in species incompatibility. within family macropodidae (kangaroos, wallabies, bettongs, and potoroos), which exhibit recent and extensive karyotypic evolution, rearrangements involve chiefly the centromere. we propose that centromeres are the primary target for destabilization in cases of genomic instability, such a ... | 2007 | 18073443 |
| host-parasite associations of eimeria spp. (apicomplexa:eimeriidae) in kangaroos and wallabies of the genus macropus (marsupialia:macropodidae). | faecal samples from 514 kangaroos and wallabies representing 12 species of the genus macropus were examined for oocysts of eimeria spp. six species of eimeria were redescribed from their type hosts, and on the basis of finding homologous oocysts in the faeces of other macropus spp., host ranges for these coccidia were extended. eimeria hestermani mykytowycz, 1964 is redescribed from m. giganteus (eastern grey kangaroo) and is described from m. fuliginosus (western grey kangaroo), m. rufogriseus ... | 1989 | 2759765 |
| repeated dna sequences and kangaroo phylogeny. | three highly repeated dna sequences have been used to determine relationships of species within the macropodidae (kangaroos and wallabies). two highly repeated dna sequences were isolated as buoyant density satellites in the red-necked wallaby and in the wallaroo-euro group. the third probe was a cloned representative of one class of highly repeated species from the red kangaroo. radioactively labelled probes of these three repeated sequences were used to determine the incidence and distribution ... | 1981 | 7295212 |
| composition of marsupial zona pellucida: a molecular and phylogenetic approach. | the zona pellucida (zp) is an extracellular matrix that surrounds mammalian oocytes. in eutherians it is formed from three or four proteins (zp1, zp2, zp3, zp4). in the few marsupials that have been studied, however, only three of these have been characterised (zp2, zp3, zp4). nevertheless, the composition in marsupials may be more complex, since a duplication of the zp3 gene was recently described in one species. the aim of this work was to elucidate the zp composition in marsupials and relate ... | 2017 | 29162213 |
| isolation of major histocompatibility complex class i genes from the tammar wallaby (macropus eugenii). | the major histocompatibility complex (mhc) plays an essential role in the adaptive immune system of vertebrates through antigen recognition. although mhc genes are found in all vertebrates, the mhc region is dynamic and has changed throughout vertebrate evolution, making it an important tool for comparative genomics. marsupials occupy an important position in mammalian phylogeny, yet the mhc of few marsupials has been studied in detail. we report the isolation and analysis of expressed mhc class ... | 2006 | 16568263 |
| therapeutics of companion exotic marsupials. | exotic marsupials are becoming popular companion pets, yet little pharmacologic information is available to the practitioner. species include sugar gliders (petarus breviceps), south american (brazilian) short-tailed opossums (monodelphis domestica), brushtail possum or "phalanger" (trichosurus vulpecula), and wallabies: bennett's (macropus rufogriseus rufogriseus) and tammar or dama (macropus eugenii). guidelines for logical choices of medications based on allometric scaling, gastrointestinal t ... | 2000 | 11228826 |
| mesotocin and luteal function in macropodid marsupials. | pituitary glands and corpora lutea collected at various stages of the reproductive cycle of the tammar wallaby (macropus eugenii), were extracted and fractionated by high-performance liquid chromatography, and specific radioimmunoassays were used to measure mesotocin ([ile8]-oxytocin) and oxytocin. mesotocin, but not oxytocin, was identified in extracts of pituitary; the mean concentration of mesotocin in this tissue was 0.75 nmol/g wet weight. neither mesotocin nor oxytocin was detected in extr ... | 1988 | 3392493 |
| ecological specialisation in habitat selection within a macropodid herbivore guild. | specialist species show stronger resource selection, narrower niches and lower niche overlap than generalist species. we examined ecological specialisation with respect to habitat selection in a macropodid community comprising the western grey kangaroo macropus fuliginosus, red-necked wallaby m. rufogriseus and swamp wallaby wallabia bicolor in the grampians national park, victoria, australia. we used radio tracking to quantify habitat selection. we predicted that because the fitness benefits of ... | 2016 | 26621691 |
| early expression of manual lateralization in bipedal marsupials. | robust lateralization in forelimb use has recently been found in bipedal, but not quadrupedal, marsupial mammals. the link between bipedality and handedness, occurring in both marsupials and primates, remains to be investigated. to shed light on the developmental origins of marsupial manual lateralization, infants of macropod marsupials were examined before and shortly after the acquisition of habitual bipedal posture and locomotion. forelimb preferences were assessed in natural, not artificiall ... | 2017 | 28287756 |
| interspecific variation in the diets of herbivores in an industrial environment: implications for exposure to fluoride emissions. | atmospheric fluorides (gaseous and particulate) are deposited on, and absorbed by, vegetation. ingested fluoride accumulates in calcified tissues of vertebrates, and if it is excessive, it may lead to dental and skeletal fluorosis. the prevalence, form and severity of the effects vary greatly between species. foraging strategy can be an important determinant of fluoride exposure in herbivores, because foliar fluoride concentrations vary between plant species, for example, according to vertical a ... | 2016 | 26873827 |
| dental fluorosis and skeletal fluoride content as biomarkers of excess fluoride exposure in marsupials. | particulate and gaseous fluoride emissions contaminate vegetation near fluoride-emitting industries, potentially impacting herbivorous wildlife in neighboring areas. dental fluorosis has been associated with consumption of fluoride-contaminated foliage by juvenile livestock and wildlife in europe and north america. for the first time, we explored the epidemiology and comparative pathology of dental fluorosis in australian marsupials residing near an aluminium smelter. six species (macropus gigan ... | 2015 | 26188404 |

| newly described toxoplasma gondii strain causes high mortality in red necked wallabies (macropus rufogriseus) in a zoo. | this manuscript describes an outbreak of fatal toxoplasmosis in wallabies. ten adult red necked wallabies (macropus rufogriseus) were imported from new zealand to the virginia zoo. agglutination testing upon admission into quarantine showed all animals to be negative for antibodies to toxoplasma gondii. nine of these wallabies died from acute toxoplasmosis within 59-565 (average 224) days after being moved onto exhibit. clinical signs included lethargy, diarrhea, tachypnea, and ataxia that progr ... | 2017 | 28920810 |
| use of oral fluoxetine for the treatment of abnormal aggression in two red-necked wallabies (macropus rufogriseus). | : abnormal inter- and intraspecies aggression, perceived to be anxiety related, was identified in two male red-necked wallabies (macropus rufogriseus) housed within a zoo. aggressive episodes were directed at conspecifics, other exhibit animals, and, in one case, human caretakers. the clinical use of oral fluoxetine (0.5 mg/kg po bid) for a period of approximately 4 mo was effective in eliminating aggression towards humans and other animals in these two individuals. there was no evidence of recr ... | 2017 | 28920807 |
| pharmacokinetics of intravenous clindamycin phosphate in captive bennett's wallabies (macropus rufogriseus). | this study was designed to investigate the pharmacokinetics of clindamycin, a lincosamide antibiotic, in bennett's wallabies. the pharmacokinetic properties of a single intravenous (iv) dose of clindamycin were determined in six wallabies. a single 20-min iv infusion of 20 mg/kg of clindamycin was administered, followed by blood collection prior to, and up to 12 hr after clindamycin administration. plasma clindamycin concentrations were determined by high-pressure liquid chromatography (hplc) wi ... | 2017 | 28568310 |
| comparison of medetomidine-ketamine and butorphanol-azaperone-medetomidine in captive bennett's wallabies (macropus rufogriseus). | the objective of this study was to compare a traditional partially reversible medetomidine-ketamine sedation with a more reversible butorphanol-azaperone-medetomidine combination in bennett's wallabies ( macropus rufogriseus ) maintained in a zoological collection. fourteen animals were divided into two treatment groups. individuals in group 1 received an intramuscular (i.m.) injection of butorphanol (0.54 ± 0.05 mg/kg), azaperone (0.22 ± 0.02 mg/kg), and medetomidine (0.16 ± 0.02 mg/kg). indivi ... | 2016 | 28080912 |
| ultrasound-guided femoral and sciatic nerve blocks for repair of tibia and fibula fractures in a bennett's wallaby (macropus rufogriseus). | locoregional anesthetic techniques may be a very useful tool for the anesthetic management of wallabies with injuries of the pelvic limbs and may help to prevent capture myopathies resulting from stress and systemic opioids' administration. this report describes the use of ultrasound-guided femoral and sciatic nerve blocks in bennett's wallaby (macropus rufogriseus) referred for orthopaedic surgery. ultrasound-guided femoral and sciatic nerve blocks were attempted at the femoral triangle and pro ... | 2016 | 27803817 |
| prothrombin time and activated partial thromboplastin time using a point-of-care analyser (abaxis vspro®) in bennett's wallabies (macropus rufogriseus). | there are few reports of coagulation times in marsupial species. blood samples collected from 14 bennett's wallabies (macropus rufogriseus) under anaesthesia during routine health assessments were analysed for prothrombin time (pt) and activated partial thromboplastin time (aptt) using a point-of-care analyser (poc) (abaxis vspro®). the wallabies had an aptt mean of 78.09 s and median of 78.1 s. the pt for all wallabies was greater than 35 s, exceeding the longest time measured on the poc. altho ... | 2016 | 27671083 |
| motor and postural asymmetries in marsupials: forelimb preferences in the red-necked wallaby (macropus rufogriseus). | in the last decades, several studies on mammal motor lateralization have been carried out. however, data on marsupials are still underrepresented in the literature, despite their importance in tracing the evolution of motor laterality and its functional value. this study aimed at investigating motor lateralization in a sample of captive red-necked wallabies (macropus rufogriseus), considering different daily unimanual activities and forelimb implication in postural support. data on forelimb pref ... | 2016 | 27150458 |
| surgical correction of a cervical spinal fracture in a bennett's wallaby (macropus rufogriseus). | macropods are susceptible to trauma, and fractures of the cervical vertebrae due to collisions are relatively common. a 4-yr-old, intact male bennett's wallaby (macropus rufogriseus) was presented acutely nonambulatory and tetraparetic but with motor function present in all limbs. cervical radiographs revealed a c4 vertebral fracture. surgical stabilization was obtained through a ventral midline approach whereby the vertebral bodies were distracted and then secured with screws and polymethylmeth ... | 2016 | 27010308 |
| phylogenetic relationships of species of the oesophageal parasitic nematode genera cyclostrongylus and spirostrongylus (strongyloidea: chabertiidae: cloacininae) with their wallaby hosts (marsupialia: macropodidae). | a phylogeny for seven species of cyclostrongylus and the monotypic genus spirostrongylus (nematoda: chabertiidae), all highly host specific parasites of the oesophagi of wallabies (marsupialia: macropodidae), was constructed using sequence data for the first and second internal transcribed spacers (its-1 and its-2) of the nuclear ribosomal dna. there was no evidence for co-speciation, or for the sympatric or synxenic speciation of cyclostrongylus alatus and cyclostrongylus perplexus, both of whi ... | 2016 | 26802594 |
| peace-making in marsupials: the first study in the red-necked wallaby (macropus rufogriseus). | the issue of reconciliation has been widely investigated in many eutherian mammal species. nevertheless, no data are available for marsupial mammals. indeed, the majority of reports focus on group dynamics from an ecological and reproductive perspective, but no study has investigated them from a social point of view. we observed the red-necked wallaby colony (macropus rufogriseus) hosted at the tierparc zoo berlin (germany) and collected data on aggressive and post-conflict interactions between ... | 2014 | 24489796 |
| naturally acquired visceral leishmaniosis in a captive bennett's wallaby (macropus rufogriseus rufogriseus). | a high prevalence of leishmaniosis has been reported from an increasing number of domestic and wild mammals around the world. in australian macropods, leishmania spp infection has been occasionally described in its cutaneous form only. the purpose of this report is to present a case of fatal visceral leishmaniosis in a captive bennett's wallaby in madrid, spain, which was investigated by detailed macroscopic, histologic, and immunohistochemical examinations. | 2013 | 22692623 |
| methane production by red-necked wallabies (macropus rufogriseus). | the claimed low production of ch(4) by kangaroos and marsupials in general has been questioned because of a lack of data. the extent of their ch(4) production is of interest both from the point of view of discussing meat production of marsupials and as a basis for developing methods to reduce ch(4) production from ruminants. in the present experiment, the ch(4) production of 8 red-necked wallabies (macropus rufogriseus) was measured of which 4 were fed 2 different diets in an open-circuit respir ... | 2012 | 22408184 |
| evaluation of medetomidine-alfaxalone and medetomidine-ketamine in semi-free ranging bennett's wallabies (macropus rufogriseus). | twenty-six adult semi-free-ranging bennett's wallabies were anesthetized. animals in group ma received medetomidine 0.1 mg/kg and alfaxalone 4 mg/kg i.m. in a 5-ml dart, whereas those in group mk received medetomidine 0.1 mg/kg and ketamine 5 mg/kg i.m. in a 3-ml dart. dosages were based on estimated body weights. the wallabies were allowed to recover spontaneously or, if still nonresponsive at the end of the procedure, were given atipamezole 0.5 mg/kg (half the dose via i.m. and the other half ... | 2011 | 22204056 |
| sperm motility activation, sperm heterogeneity and sperm-female tract interactions in bennett's wallaby (macropus rufogriseus rufogriseus). | sperm-oviduct interactions in bennett's wallaby (macropus rufogriseus rufogriseus) were investigated using in vitro cocultures of cauda epididymal spermatozoa and oviducal epithelial cells. kidney epithelial cells were used as non-reproductive control tissues. spermatozoa attached to epithelial cells of both origins, but sperm survival and activity was higher when cocultured with oviducal cells. new findings during live sperm-epithelial interactions included: (1) a high frequency of reversible h ... | 2011 | 21557927 |
