the prevalence of sarcosporidiosis in australian meat animals.the prevalence of sarcocystis infectious in tasmanian sheep, cattle and pigs was assessed during february 1974. serological results indicated that over 90% of sheep and cattle were infected. macroscopic sarcocysts were found in 0.6% of lambs, 8.8% of 2- to 6-tooth (1 to 4 years old) sheep and 66% of full-mouth (4 years and older) sheep. the minimum prevalence in pigs, as determined by microscopic examination of muscle tissues, was 1.4% for animals less than 12 months old and 16.7% for animals ol ...1975812465
the control of hydatid disease and ovine cysticercoses in the australian capital territory and southern new south wales.a survey of human hydatid disease in new south wales and the australian capital territory over the period 1968 to 1973 was made from hospital records in sydney and canberra. the 162 new cases found represent an incidence, of 0-57 per 100,000 per annum, but the 20 patients living in the central west statistical division of new south wales at the time of admission to hospital represent an incidence of 12-6 per 100,000 per annum in that area. a survey of a.c.t. farms revealed dogs carrying the caus ...1977875855
internal parasites of feral cats from the tasmanian midlands and king island.eighty-six feral cats from a sheep grazing area in the tasmanian midlands and 21 from king island were examined for internal parasites. major food items in order of decreasing prevalence in stomach contents were insects, lizards, birds, rodents and frogs in the midlands, and rodents, birds, insects, and lizards on king island. feral cats from the midlands had 4 cestode, 7 nematode, 2 trematode and 3 protozoan parasites as follows: spirometra erinacei (66.3%), taenia taeniaeformis (2.3%), dipylid ...1976985246
congenital bovine epizootic arthrogryposis and hydranencephaly in australia. distribution of antibodies to akabane virus in australian cattle after the 1974 the end of the 1974 epizootic of bovine congenital arthrogryposis and hydranencephaly in south-eastern new south wales, an australia-wide serological survey (about 4,000 serums) was made to determine the ditribution of cattle possessing serum neutralising antibodies against akabane virus. eighty per cent of the serums from cattle in northern australia (western australia, northern territory, and queensland) were positive. a detailed study in the epizootic area in new south wales (particularly ...19761016149
a reconsideration of the echinococcus granulosus strain situation in australia following rflp analysis of cystic material.restriction fragment length polymorphism (rflp) analysis, previously shown to be a relatively simple and reproducible method for distinguishing discrete strains of e. granulosus, could not discriminate between e. granulosus originating from central queensland macropod marsupials, australian mainland sheep or united kingdom sheep. furthermore, sheep cyst material from tasmania and the australian mainland was indistinguishable using this approach. as a result of this dna analysis, the existence of ...19911680829

control of echinococcus granulosus in cyprus and comparison with other island models.a control programme directed against echinococcus granulosus was introduced into the republic of cyprus in 1971. in 1974, this was restricted to the areas controlled by the government of the island. the force used in the 'attack' phase included a major dog control programme. this and other measures led to the rapid 'disappearance' of the parasite and control was terminated in 1985. subsequent studies during 1993-1996 revealed that the parasite was present in 82 (20%) villages in either dogs or f ...19989806495
molecular epidemiology of mycobacterium avium subsp. paratuberculosis: is900 restriction fragment length polymorphism and is1311 polymorphism analyses of isolates from animals and a human in australia.the distribution and prevalence of strains of mycobacterium avium subsp. paratuberculosis were determined among sheep, cattle, and other species with johne's disease in australia. a total of 328 isolates were evaluated from numerous farms in new south wales, victoria, tasmania, and south australia, australia. restriction fragment length polymorphism (rflp) analysis of genomic dna using bsteii and an is900 probe and is1311 polymorphism analysis using pcr and restriction endonuclease analysis (pcr ...200010970365

hydatid control in australia: where it began, what we have achieved and where to from here.echinococcus granulosus was imported into australia with domestic livestock about 200 years ago. it spread rapidly through domestic animals and quickly became a public health problem in the new colony. control was hampered by ignorance of the transmission pattern. the association between metacestodes and tapeworms was not elucidated until 63 years after the arrival of the first fleet. australian wildlife were highly susceptible to infection with e. granulosus and wildlife/domestic animal interac ...200515907851
control of cystic echinococcosis/hydatidosis: 1863-2002.echinococcosis/hydatidosis, caused by echinococcus granulosus, is a chronic and debilitating zoonotic larval cestode infection in humans, which is principally transmitted between dogs and domestic livestock, particularly sheep. human hydatid disease occurs in almost all pastoral communities and rangeland areas of the underdeveloped and developed world. control programmes against hydatidosis have been implemented in several endemic countries, states, provinces, districts or regions to reduce or e ...200616735171
blowfly succession from possum (trichosurus vulpecula) carrion in a sheep-farming zone.the significance of brushtail possum, trichosurus vulpecula kerr (diprotodontia: phalangeridae) carcasses to the succession and production of diptera species and its relevance to fly strike management in tasmania, australia was examined. calliphora stygia (fabricius), lucilia sericata (meigen) and calliphora vicina robineau-desvoidy (diptera: calliphoridae) were found to be the most abundant and lucilia cuprina (wiedemann) (diptera: calliphoridae) always the least abundant (< 1%) of the putative ...200617199756
maternal alcohol intake and offspring pulse wave velocity.intrauterine exposure to alcohol may affect cardiovascular development, increasing risk of cardiovascular malformations. intrauterine exposure to light maternal alcohol intake has been reported to affect human umbilical arterial contractility, and adult sheep exposed in utero have had altered cerebrovascular reactivity. in human adults, alcohol intake affects arterial stiffness.201019864927
growth and genotypes of echinococcus granulosus found in cattle imported from australia and fattened in the abattoir on study in miyazaki, japan, 9537 imported cattle from australia in average were slaughtered annually in the last 5years (2006 to 2010) and hydatid cysts were constantly detected in about 1.8% of the cattle. in order to assess the risk of echinococcus granulosus delivered to japan by imported cattle, 250 cysts found in 103 cattle at the abattoir were examined for their biological characteristics and genotypes. the cattle slaughtered were imported from australia at an age of 10-12 ...201121930239
linkage disequilibrium compared between five populations of domestic sheep.the success of genome-wide scans depends on the strength and magnitude of linkage disequilibrium (ld) present within the populations under investigation. high density snp arrays are currently in development for the sheep genome, however little is known about the behaviour of ld in this livestock species. this study examined the behaviour of ld within five sheep populations using two ld metrics, d' and x2'. four economically important australian sheep flocks, three pure breeds (white faced suffol ...200818826649
farm injury in tasmania.the aim of the study was to provide information about the type and severity of farming injury. data were collected from industrial members of the tasmanian farmers and graziers association, using a valid and reliable self administered retrospective questionnaire covering the previous 2 years. a total of 506 responses were obtained, with 38% indicating there had been at least one injury sustained on their farm during this period. of those reporting an injury, 18% were admitted, 30% attended an em ...200111736843

embryonic duplications in sheep.twenty-seven embryonic duplications were examined during a 3-year investigation into the causes of perinatal lamb mortality. twenty of the 27 were anomalous twins with 19 being conjoined (diplopagus 9 and heteropagus 10). the various duplications were: haloacardius acephalus 1, diprosopus 2, dicephalus 2, dipypus 3, diprosopus dipygus 1, syncephalus dipygus 1, pygopagus parasiticus 1, heteropagus dipygus 3, melodidymus 6, polyury 4, penile duplication 2, and bilateral otognathia 1. four lambs we ...19751172431
the incidence of dystocia in dorset horn ewes.the incidence of dystocia was recorded in flocks of dorset horn ewes lambing in winter, spring or summer and grazed at 8, 12 or 16 ewes per hectare over a ten-year period. the mean incidence of dystocia was 34% of ewes lambing. significantly more ewes experience a difficult birth at winter (35%) and spring (39%) than summer (26%) lambings. neither stocking rates nor pre-lambing ewe bodyweight were related to the incidence of dystocia. the incidence of dystocia was significantly greater in 2-year ...19761016153
plasma thyroxine concentrations in grazing sheep in several areas of australia.plasma thyroxine concentrations were measured by radioimmunoassay in plasma samples from 691 lactating ewes in 26 areas of new south wales, queensland, western australia and tasmania. sheep sampled in new south wales and tasmania had significantly lower plasma thyroxine values (4.0 and 4.3 microgram/100 ml respectively) than those sampled in queensland and western australia (5.4 and 5.3 microgram/100 ml respectively). however, sheep in some districts in southern queensland also had low plasma th ...1978567054
human behaviour and the ethics of coercion.there is an assumption that legislation against unhealthy behaviour would be unethical, or at best unenforceable and counterproductive. however, the ethics of coercion depend on the manner in which such coercion is introduced, the essential precondition being wide, favourable community consensus. two recent australian examples have been the victorian seat-belt legislation and the tasmanian hydatid campaign. hydatid control in tasmania began with a voluntary campaign in the farming community whic ...19883336342
