determination of mosquito (diptera: culicidae) bloodmeal sources in western australia: implications for arbovirus transmission.a double-antibody enzyme-linked immunosorbent assay was used to determine the bloodmeal sources of adult mosquitoes (diptera: culicidae) collected in encephalitis vector surveillance mosquito traps in western australia between may 1993 and august 2004. in total, 2,606 blood-fed mosquitoes, representing 29 mosquito species, were tested, and 81.7% reacted with one or more of the primary antibodies. aedes camptorhynchus (thomson) and culex annulirostris skuse were the most common species tested, ma ...200919769051
biological control of nematode parasites in sheep.in a world in which sheep producers are facing increasing problems due to the rapid spread of anthelmintic resistance, the battle against gastrointestinal parasitic nematodes is a difficult one. one of the potential new tools for integrated control strategies is biological control by means of the nematode-destroying microfungus duddingtonia flagrans. this fungus forms sticky traps that catch developing larval stages of parasitic nematodes in the fecal environment. when resting spores (chlamydosp ...200616582084
sensitivity and specificity of two serological tests for the detection of ovine paratuberculosis.to determine the sensitivity and specificity of an absorbed elisa and an agid test for the detection of clinical and subclinical paratuberculosis in sheep.200011194475
dna tests in prolific sheep from eight countries provide new evidence on origin of the booroola (fecb) mutation.recent discoveries that high prolificacy in sheep carrying the booroola gene (fecb) is the result of a mutation in the bmpib receptor and high prolificacy in inverdale sheep (fecx(i)) is the result of a mutation in the bmp15 oocyte-derived growth factor gene have allowed direct marker tests to be developed for fecb and fecx(i). these tests were carried out in seven strains of sheep (javanese, thoka, woodlands, olkuska, lacaune, belclare, and cambridge) in which inheritance patterns have suggeste ...200212021074
a survey of western australian sheep, cattle and kangaroos to determine the prevalence of coxiella burnetii.the objective of this study was to investigate the prevalence of coxiella burnetii in two domestic ruminant species (cattle and sheep) and the western grey kangaroo (macropus fuliginosus) in western australia (wa). the idexx chekit q fever elisa and cft were used to test sera from 50 sheep and 329 head of cattle for anti-c. burnetii antibodies and 343 kangaroo sera were tested using an indirect elisa developed specifically for this study. faecal or urine samples collected from the same animals w ...201020036083

toxigenicity of enniatins from western australian fusarium species to brine shrimp (artemia franciscana).the high prevalence (14 of 24 isolates) of enniatin-producing isolates from western australian fusarium species isolated from pasture legumes associated with sheep feed refusal and rat deaths, and the high toxicity of their crude extracts to brine shrimp (artemia franciscana) from a previous study warranted further investigation of this class of mycotoxin. crude extracts from fusarium acuminatum, fusarium avenaceum, fusarium tricinctum and fusarium sambucinum, along with enniatins a, a1, b and b ...201121352844
age and nutrition influence the concentrations of three branched chain fatty acids in sheep fat from australian abattoirs.the characteristic mutton odour, associated with the cooked meat of older sheep, can be problematic for some consumers who find the odour disagreeable. branch chain fatty acids (bcfas) are considered to be the main determinants of mutton odour. in this study, the aim was to identify the factors influencing the bcfa content of animals at abattoirs in australia. samples of subcutaneous fat from over the chump (gluteus medius) were collected from 533 sheep carcasses at abattoirs in new south wales, ...201020696535
association between nematode larvae and "low worm egg count diarrhoea" in sheep in western australia.nine flocks of sheep with a high prevalence (>30%) of diarrhoea and severe breech faecal soiling were investigated over a three-year period to examine the causes of diarrhoea in sheep with low mean faecal worm egg counts (wec). all nine flocks were located in the southwest of western australia in areas with a winter rainfall pattern (mediterranean climate). there was no difference (p=0.304) in wec of diarrhoeic sheep (loose faeces and severe breech faecal soiling) and "normal sheep" (pelleted fa ...200919682795

variable ventilation improves ventilation and lung compliance in preterm lambs.purpose: in adult animals, ventilation with variable tidal volume and rate improves lung mechanics, arterial oxygenation and ventilation compared to a monotonously controlled ventilation pattern. we assessed the physiological consequences of variable ventilation in the immature lung. methods: lambs delivered at 129 days (term = 150 days) were euthanised (n = 9) or anaesthetised, tracheostomised and suctioned prior to prophylactic intra-tracheal surfactant instillation (curosurf(®), 100 mg/kg) an ...201121567115
pulmonary and systemic expression of monocyte chemotactic proteins in preterm sheep fetuses exposed to lipopolysaccharide-induced chorioamnionitis.monocyte chemoattractant proteins (mcp-1 and mcp-2) mediate monocyte and t-lymphocyte chemotaxis, and il-1 contributes to the pathogenesis of chorioamnionitis-induced lung inflammation and fetal inflammatory responses. we tested the hypothesis that il-1 mediates the systemic and pulmonary induction of mcp-1 and mcp-2 in response to lipopolysaccharide (lps)-induced chorioamnionitis. mcp-1 mrna, mcp-2 mrna, and mcp-1 protein expression were measured in two models: 1) intra-amniotic lps and 2) intr ...201020703142

prevalence and molecular characterisation of cryptosporidium and giardia species in pre-weaned sheep in australia.a total of 477 faecal samples from pre-weaned sheep from 5 different farms in the south west of western australia were screened for the presence of cryptosporidium and giardia using pcr. there were substantial differences in prevalence between the farms and overall prevalence was 24.5% and 11.1%, respectively for cryptosporidium and giardia. at the 18s locus, 66 cryptosporidium positives were identified, the majority of which were c. bovis (n=52), followed by the cervid genotype (n=10) and c. pa ...200919195787
current value of historical and ongoing surveillance for disease freedom: surveillance for bovine johne's disease in western australia.'confidence' in freedom from disease is generally derived from multiple sources of varied surveillance information, and typically this surveillance evidence has been accumulated over time. in the state of western australia (wa) the main surveillance evidence supporting free zone status in the national bovine johne's disease (bjd) program comprises periodic surveys and the ongoing clinical diagnostic system. this paper illustrates a simple approach to current valuation of historical surveillance ...200818243373
detection and diversity of a putative novel heterogeneous polymorphic proline-glycine repeat (pgr) protein in the footrot pathogen dichelobacter nodosus.dichelobacter nodosus, a gram-negative anaerobic bacterium, is the essential causative agent of footrot in sheep. currently, depending on the clinical presentation in the field, footrot is described as benign or virulent; d. nodosus strains have also been classified as benign or virulent, but this designation is not always consistent with clinical disease. the aim of this study was to determine the diversity of the pgr gene, which encodes a putative proline-glycine repeat protein (pgr). the pgr ...201120655152
understanding the molecular epidemiology of the footrot pathogen dichelobacter nodosus to support control and eradication programs.the gram-negative anaerobe dichelobacter nodosus is the primary etiologic agent of ovine footrot. few studies of the genetic diversity and epidemiology of d. nodosus have been done, despite the economic cost and welfare implications of the disease. this study examined a large collection of australian isolates; 735 isolates from footrot-infected sheep from 247 farms in western australia (wa) were tested by pulsed-field gel electrophoresis (pfge), and a subset of 616 isolates was tested by infrequ ...201020071558

a note on the reproductive performance of damara, dorper and merino sheep under optimum management and nutrition for merino ewes in the eastern wheatbelt of western australia.the reproductive performance of 48 damara, 42 dorper and 46 merino ewes was evaluated under an optimum nutritional regime for merino ewes that included one annual joining in a mixed (cropping and sheep) farming system in the eastern wheatbelt of western australia (w.a.) over a 3-year period. in 2005, when the damara, dorper and merino ewes were aged between 8 and 9-ámonths at joining and weighed 41.2, 42.4 and 33.3-ákg with average body condition scores of 2.3, 2.4 and 1.8, respectively, their w ...201121725705
prevalence and on-farm risk factors for diarrhoea in meat lamb flocks in western australia.diarrhoea is a widespread problem for sheep enterprises worldwide. a cross-sectional epidemiological study was conducted using a questionnaire to determine the prevalence of diarrhoea and associated risk factors where there was evidence of recent diarrhoea (active diarrhoea or fresh faecal soiling of breech fleece) for meat lambs on farms in southern western australia during 2010. the response rate was 41.4% (139/336). evidence of recent diarrhoea was reported on 64.8% of farms, with a mean of 6 ...201121903430
estimated intakes of meat and fish by children and adolescents in australia and comparison with recommendations.long-chain n-3 pufa are considered important for cardiovascular health and brain development. meat other than fish contributes significantly to total intakes of long-chain n-3 pufa in adults; however, there are limited published data examining the intake of individual meat sources in children and adolescents in the australian population. a review of literature was conducted using pubmed, agricola and cab abstracts using the terms 'intake', 'beef', 'lamb', 'pork', 'poultry', 'fish', 'children' an ...200919055853
longitudinal investigation of protozoan parasites in meat lamb farms in southern western australia.in this study, 96 faecal samples were collected from pregnant merino ewes, at two broad-acre, commercial sheep farms in southern western australia, on two separate occasions (16 and 2 weeks prior to lambing). following lambing, 111 (farm a) and 124 (farm b) female crossbred lambs (2-6 weeks old), were individually identified using ear tags (a numbered tag and a radio-frequency tag). a total of 1155 faecal samples were collected only from these individually identified lambs on five separate sampl ...201121733584
calm merino ewes have a higher ovulation rate and more multiple pregnancies than nervous ewes.in 1990, two selection lines of merino sheep were established for low and high behavioural reactivity (calm and nervous temperament) at the university of western australia. breeding records consistently showed that calm ewes weaned 10% to 19% more lambs than the nervous ewes. we hypothesise that calm ewes could have a higher ovulation rate than nervous ewes and/or calm ewes could have a lower rate of embryo mortality than nervous ewes. we tested these hypotheses by comparing the ovulation rate a ...201728183365
