myxomatosis on the western plains of victoria.myxomatosis on the western plains is an enzootic disease in contrast with the epizootic pattern which is general in eastern australia. the most unusual aspects are the presence of significant numbers of diseased rabbits throughout the winter and the continuously low percentage of rabbits with antibodies to myxoma virus. climatic and topographic conditions are unsuited to the production of the high densities of mosquitoes necessary for widespread epizootics. under these conditions the effects of ...197720473
myxomatosis: the transmission of a highly virulent strain of myxoma virus by the european rabbit flea sphilopsyllus cuniculi (dale) in the mallee region of victoria.the european rabbit flea spilopsyllus cuniculi (daley was introduced into australia to act as a vector of myxoma virus. it was first released in the semi-arid mallee region of victoria in 1970 where epizootics cuased by field strains of myxoma virus occur each summer. introductions of the readily identified lausanne strain were made annually following the release of the flea. the introductions were successful and the strain persisted for up to 16 weeks despite competition from field strains. the ...1977270525
myxomatosis: the release and spread of the european rabbit flea spilopsyllus cuniculi (dale) in the central district of victoria.the european rabbit flea was first released in victoria in august 1969 at werribee. releases were made on five different land forms. at one site the first flea was recovered 2 weeks after release. fleas were recovered between 4 and 6 weeks after release at the other sites. differences in establishment and spread on the different land forms were due to physically restricted movement of some rabbit populations. by june 1971 80% of rabbits were infested but an occasional young uninfested rabbit was ...1979489962
myxomatosis: changes in the epidemiology of myxomatosis coincident with the establishment of the european rabbit flea spilopsyllus cuniculi (dale) in the mallee region of victoria.outbreaks of myxomatosis during the winter or spring have coincided with the establishment of the european rabbit flea in the mallee region. the severity of these outbreaks has varied from causing complete suppression of the normal spring increase in rabbit numbers to being completely ineffective in a year in which late spring rains allowed rabbit breeding to extend into the early summer.in 1973 and 1974 effective spring myxomatosis caused heavy mortality in kittens before they emerged from the ...1978569676
myxomatosis in the mallee region of victoria, australia.sharp reductions in the wild rabbit (oryctolagus cuniculus (l.)) population in the mallee are associated with annual myxomatosis epizootics. the extent to which the population reductions are the direct result of the epizootics varies with time of epizootic occurrence. all grazing animals in the mallee are under nutritional stress each summer and autumn. when the epizootic occurs during the early summer heavy losses occur in a previously healthy population. similar losses which occur in the late ...1978701787
myxomatosis: the occurrence of antibody to a soluble antigen of myxoma virus in wild rabbits, oryctolagus cuniculus (l.), in victoria, australia.the occurrence of antibody of myxoma virus in wild rabbits following epizootics is highest in the semi-arid north-west of victoria and lowest in temperate southern victoria. occurrence ranges up to about 90% in the north-west and to about 70% in the south except on the western plains where epizootics are rare and antibody occurrence seldom exceeds 30%. the establishment of the european rabbit flea may be changing the pattern of occurrence of antibody in the north-west by causing spring outbreaks ...1978701788
replantation and reconstructive microvascular surgery. part i.although the operating microscope was introduced more than 50 years ago, its use was at first confined to otolaryngology and, later, to ophthalmology. more recently its use in the development of microvascular techniques has led to spectacular advances in the field of replantation and reconstructive surgery. the organization of microsurgical research at st vincent's hospital, melbourne, is briefly described and clinical experience at this hospital over the past 10 years is reviewed. this includes ...1976817640
population genetics of aa and ab immunoglobulin allotypes in wild rabbits of south-eastern australia. i. allotype frequencies.aa and ab allotype frequencies have been investigated in wild rabbit populations throughout victoria and south-east south australia. the overall mean allele frequencies for thirty-three populations are 0-53:0-12:0-36 for a1:a2:a3 and 0-72:0-22:0-05 for b4:b5:b9. the b6 allele was not found anywhere. the a1 frequency has been found to increase in proportion to increases in mean annual rainfall. while considerable variations exist in allotype and allele frequencies from area to area, the relations ...1977925349
myxomatosis: the virulence of field strains of myxoma virus in a population of wild rabbits (oryctolagus cuniculus l.) with high resistance to myxomatosis.the virulence of field strains of myxoma virus is increasing in the mallee region of victoria where the resistance of the rabbit to myxomatosis is high. this suggests that the climax association will be a moderately severe disease.19751056963
molecular and serological analyses of two bovine rotaviruses (b-11 and b-60) causing calf scours in australia.fecal specimens from 78 calves involved in outbreaks of calf diarrhea which occurred in three farms in victoria, australia, in 1988 were analyzed for rotaviruses. thirty-eight samples were positive for group a virus antigen by enzyme-linked immunosorbent assay, and 20 of these contained viral double-stranded rnas that could be detected by polyacrylamide gel electrophoresis. two major electropherotypes could be observed, and a representative isolate of each electropherotype (isolates b-11 and b-6 ...19921310336
review of animal mycoses in australia.this review covers the available literature on the mycoses of animals in australia since the last review published in 1967. of the cutaneous infections, dermatophytoses have been recorded in a wide range of animals: cattle, horses, goats, pigs, sheep, cats, dogs, mice, guinea-pigs, rabbits, a lion, kangaroos, a camel, koalas and wallabies. these infections were caused by several species and varieties of the genera, microsporum and trichophyton. eight agents of ringworms have been recorded in the ...19902233984
enzyme-linked immunosorbent assays for detecting antibody to rickettsia australis in sera of various animal species.new endemic areas of spotted fever-like rickettsial disease have been found in south-eastern australia (gippsland, victoria and flinders island, tasmania). the rickettsia responsible is currently unknown although it may be rickettsia australis. to investigate serological evidence of rickettsial exposure in various wild animal species, a competitive elisa was developed which detected antibodies to r. australis. it was based on inhibition of an indirect elisa detecting antibody to r. australis in ...19902292182

levels of trace elements in the liver and diet of free-living koalas, phascolarctos cinereus (goldfuss).the mean liver concentrations of copper, manganese, zinc and cobalt were 0.25, 0.20, 2.97 mmol/kg and 2.81 mumol/kg respectively in free-living koalas in victoria, australia. the mean plasma copper concentration was 9.2 mmol/liter which was somewhat below the level in other hindgut fermenters. the mean concentrations of copper, manganese and zinc in their diet (eucalyptus spp.) were 0.08, 4.46 and 0.27 mmol/kg respectively. analysis of the data established a significant correlation between the a ...19846492324
lack of serological evidence for venereal spirochaetosis in wild victorian rabbits and the susceptibility of laboratory rabbits to treponema paraluis-cuniculi.sera from 608 wild rabbits were examined using serological tests for syphilis as an indicator of infection with treponema paraluis-cuniculi. only eight sera gave positive or weakly positive results in the rapid plasma reagin (rpr) test, and none of these eight sera gave positive results in the treponema pallidum haemagglutination assay (tpha). thus, it appears that wild rabbit populations in victoria, australia, are not naturally infected with t paraluis-cuniculi. normal australian laboratory ra ...19806893808
an investigation of encephalitozoon cuniculi in the wild rabbit oryctolagus cuniculus in victoria, australia.sera from 823 wild rabbits (oryctolagus cuniculus) collected from a number of geographic regions of victoria, australia over the past eight years were examined for antibodies to encephalitozoon cuniculi, along with sera from 46 hares (lepus europaeus) (pallas) and 57 new zealand wild rabbits. no sera were positive, implying that this common laboratory rabbit parasite is absent from wild rabbits in these areas. however, wild rabbits were found to be readily infected by the oral route with small n ...19806987299
toxoplasmosis and the wild rabbit oryctolagus cuniculus in victoria, australia with suggested mechanisms for dissemination of oocysts.sera or serum eluates from 1697 wild rabbits [oryctolagus cuniculus (l)], collected over the past 10 years from 24 sites in 5 geographic regions of victoria, were examined for antibodies to toxoplasma gondii. sera generally were classified into three broad groups, negative (titre less than 10), weakly reactive (titre 10 to 100) and strongly positive (titre greater than 1000). strongly positive sera came from rabbits collected in a small number of localized areas, most significantly the melbourne ...19817026675

a molecular taxonomy for cricket paralysis virus including two new isolates from australian populations of drosophila (diptera: drosophilidae).two new isolates of cricket paralysis virus, tar and sim, are described that were originally isolated from laboratory colonies of drosophila melanogaster and drosophila simulans respectively. using a combination of biological, serological and molecular characters it was possible to distinguish the sim isolate from all other isolates and it is thus described as a new strain; crpvsim. the tar isolate however, was indistinguishable from the crpv reference isolate crpvvic/gm/d2(2)/gm/d2(2) (teleogry ...19968856030
geographically diverse australian isolates of melissococcus pluton exhibit minimal genotypic diversity by restriction endonuclease analysis.melissococcus pluton, the causative agent of european foulbrood is an economically significant disease of honey bees (apis mellifera) across most regions of the world and is prevalent throughout most states of australia. 49 isolates of m. pluton recovered from diseased colonies or honey samples in new south wales, queensland, south australia, tasmania and victoria were compared using sds-page, western immunoblotting and restriction endonuclease analyses. dna profiles of all 49 geographically div ...199910227161
genetically distinct dog-derived and human-derived sarcoptes scabiei in scabies-endemic communities in northern australia.overcrowding is a significant factor contributing to endemic infection with sarcoptes scabiei in human and animal populations. however, since scabies mites from different host species are indistinguishable morphologically, it is unclear whether people can be infected from scabies-infested animals. molecular fingerprinting was done using three s. scabiei-specific single locus hypervariable microsatellite markers, with a combined total of 70 known alleles. multilocus analysis of 712 scabies mites ...199910548286
serological responses against the pathogenic dimorphic fungus mucor amphibiorum in populations of platypus (ornithorhynchus anatinus) with and without ulcerative mycotic dermatitis.mucor amphibiorum, a dimorphic fungus, causes ulcerative dermatitis and systemic infections in the platypus ornithorhynchus anatinus in some river systems in tasmania but apparently not in other regions of australia. as yet there are no suitable tests for population surveys, nor for detection of internal lesions in live animals. consequently, immunoglobulins were purified from the serum of platypuses and anti-immunoglobulin antisera were prepared in rabbits in order to develop an enzyme-linked i ...200212079747
the early days of ivf outside the uk.in this article the history of ivf in geographical regions outside the uk are traced by pioneers of that time. following the birth of louise brown in 1978, live births after ivf occurred in australia in 1980, in the usa in 1981 and in sweden and france in 1982. following the first ivf birth in australia, the government of victoria established a review of ivf research and practice which led to the proclamation of the infertility (medical procedures) act 1984, the first legislation to regulate ivf ...200515923202
in vitro oncosphere-killing assays to determine immunity to the larvae of taenia pisiformis, taenia ovis, taenia saginata, and taenia solium.taeniid cestodes infect humans and livestock, causing considerable morbidity and mortality, as well as economic loss. substantial progress has been made toward the production of recombinant vaccines against cysticercosis in livestock animals. further development of these vaccines would be aided if a reliable in vitro test were available to measure host-protective immune responses in vaccinated animals. here, we describe in vitro oncosphere-killing assays for the quantification of host-protective ...200616729683
deliberate introduction of the european rabbit, oryctolagus cuniculus, into australia.the european rabbit was brought to australia as a companion animal by early settlers. it sometimes escaped, but failed to survive in the australian bush. in 1879 wild rabbits were deliberately sent to victoria to provide game for wealthy settlers to shoot. they soon spread all over australia, except in the tropics, and became australia's major animal pest. after careful testing in australian wildlife and in humans, control by myxoma virus was introduced at various sites between 1937 and 1950, sp ...201020617651
molecular detection of cryptosporidium cuniculus in rabbits in australia.in the united kingdom, rabbits have been reported to harbour genotypes of cryptosporidium (now recognized as c. cuniculus) identical to those from human patients exhibiting symptoms of cryptosporidiosis. the high density of rabbits in many regions of australia, including both rural and urban as well as natural water catchments areas, and the absence of any information on cryptosporidium from lagomorphs in this country stimulated the present study. we undertook an epidemiological study that genet ...201020691809
disease control during the colonial period in australia.the first permanent european settlers of australia arrived in 1788 to establish a penal colony at sydney, new south wales (nsw). as the colony grew and wool production increased, more free settlers and emancipists developed farming in inland australia. during the 1840s veterinarians commenced arriving in small numbers but they were not closely associated with the development and execution of disease control programs, which was left to lay inspectors of stock. the arrival of william tyson kendall ...201121696369
interspecific and geographic variation in the diets of sympatric carnivores: dingoes/wild dogs and red foxes in south-eastern australia.dingoes/wild dogs (canis dingo/familiaris) and red foxes (vulpes vulpes) are widespread carnivores in southern australia and are controlled to reduce predation on domestic livestock and native fauna. we used the occurrence of food items in 5875 dingo/wild dog scats and 11,569 fox scats to evaluate interspecific and geographic differences in the diets of these species within nine regions of victoria, south-eastern australia. the nine regions encompass a wide variety of ecosystems. diet overlap be ...201525790230
