| the geographic distribution and host range of capillaria hepatica (bancroft) (nematoda) in australia. | the geographic distribution, host range and prevalence of capillaria hepatica were recorded in 4629 house mice, mus domesticus, 263 black rats, rattus rattus, and 58 norway rats, r. norvegicus. the parasite was found at five localities, all in or near large towns along the coast. the two rattus species appeared to be the primary hosts of c. hepatica in australia. published and unpublished data on helminth infections of australian native mammals from 1162 murids (26 species), 3018 marsupials (67 ... | 1991 | 1787037 |
| introduction of a brachylaima species (digenea: brachylaimidae) to australia. | a brachylaima species recorded previously from the house mouse (mus domesticus) in south australia is shown to use the introduced european snails cernuella virgata and cochlicella barbara as first intermediate hosts, and the same two species and theba pisana as second intermediate hosts. the life cycle is typical of brachylaima species. the parasite is capable of infecting at least two species of native australian rodent, rattus fuscipes and leporillus conditor. because of the intermediate hosts ... | 1990 | 2242962 |

| immunological types of lymphoproliferative disorders in a cohort: a 4-year study. | immunological testing of malignant cells and serum from most cases of lymphoproliferative disorders (lpd) allows the cell type to be characterised as of b, t or "null" lymphocyte origin. regional differences in the incidence of neoplasms of these types have been reported. furthermore, most published series have drawn cases from referral institutions rather than the general population. in order to determine the true incidence of a cohort we surveyed an entire population, that of tasmania, an isla ... | 1982 | 6814410 |
| locally acquired brachylaima sp. (digenea: brachylaimidae) intestinal fluke infection in two south australian infants. | eggs of a small intestinal trematode were found in the faeces of two 21-month-old children from the same rural district of south australia who presented 18 months apart with mild abdominal pain and diarrhoea. treatment with praziquantel resulted in egg clearance and resolution of gastrointestinal symptoms. a brachylaimid intestinal trematode involving the common house mouse, poultry and introduced european helicid snails is well established in south australia. both infants had been seen eating r ... | 1996 | 8614338 |
| true enamel covering in teeth of the australian lungfish neoceratodus forsteri. | lungfish are a unique order of sarcopterygian fish cleidographically positioned between tetrapods and fish. an uninterrupted 400-million-year-old fossil record has documented lungfish skeletal elements to remain virtually unchanged since the early devonian. in the current study we investigated the enamel layer of lungfish teeth in order to determine whether there was evidence for higher vertebrate "true" enamel in the australian lungfish. juvenile lungfish from the brisbane river were processed ... | 2000 | 10654067 |
| identification of a novel coch mutation, i109n, highlights the similar clinical features observed in dfna9 families. | hereditary hearing loss is a heterogeneous condition at both the genetic and clinical levels. we have recruited an australian family with dominant sensorineural nonsyndromic late onset hearing loss. the hearing loss typically begins in the second or third decade of life as a high frequency loss which progresses to a severe to profound loss by the sixth to seventh decade. all affected family members presented with concomitant vestibular dysfunction. vertigo is a less common feature. the causative ... | 2001 | 11295836 |
| preliminary evidence of toxicity associated with the benthic cyanobacterium phormidium in south australia. | in april 2000, the water supply for yorke peninsula in south australia was deemed non-potable when extracts from a proliferation of the benthic cyanobacterium phormidium aff. formosum in upper paskeville reservoir were found to be lethally toxic by intraperitoneal injection into mice (400 mg kg-1). routine water quality monitoring had failed to detect the development of the phormidium until complaints of musty taste and odour, attributable to the production of 2-methyl-isoborneol (mib), were rec ... | 2001 | 11769248 |
| experimental comparisons of data entry by automated speech recognition, keyboard, and mouse. | in a series of experiments isolated-word automated speech recognition (asr) was compared with keyboard and mouse interfaces for three data entry tasks: textual phrase entry, selection from a list, and numerical data entry. to effect fair comparisons, the tasks were designed to minimize the transaction cycle for each input mode and data type, and the main comparisons used times from only correct data entries. with the hardware and software employed the results indicate that for inputting short ph ... | 2002 | 12452268 |
| isolation and characterization of melanopsin (opn4) from the australian marsupial sminthopsis crassicaudata (fat-tailed dunnart). | melanopsin confers photosensitivity to a subset of retinal ganglion cells and is responsible for many non-image-forming tasks, like the detection of light for circadian entrainment. recently, two melanopsin genes, opn4m and opn4x, were described in non-mammalian vertebrates. however, only one form, opn4m, has been described in the mammals, although studies to date have been limited to the placentals and have not included the marsupials. we report here the isolation and characterization of an opn ... | 2007 | 17785267 |
| temporal deposition and spatial distribution of cytoskeletal proteins in the sperm head of an australian rodent. | the australian murine rodent, the plains mouse (pseudomys australis), possesses a highly complex sperm head, in which there are, in addition to an apical hook, two ventral processes that extend from its upper concave surface. the present study set out to determine the temporal deposition and distribution of the proteins within these structures during late spermiogenesis by light and electron microscopy using various antibodies to bull and laboratory rat sperm-head cytoskeletal proteins. the find ... | 2009 | 19261220 |
| ddx4 (vasa) is conserved in germ cell development in marsupials and monotremes. | ddx4 (vasa) is an rna helicase expressed in the germ cells of all animals. to gain greater insight into the role of this gene in mammalian germ cell development we characterized ddx4 in both a marsupial (the tammar wallaby) and a monotreme (the platypus). ddx4 is highly conserved between eutherian, marsupial and monotreme mammals. ddx4 protein is absent from tammar fetal germ cells but is present from day 1 postpartum in both sexes. the distribution of ddx4 protein during oogenesis and spermatog ... | 2011 | 21653890 |
