Meningoencephalomyelitis in a foal due to Salmonella agona infection     

Patterson-Kane JC  Bain FT  Donahue JM  Harrison LR 《New Zealand veterinary journal》2001,49(4):159-161

CASE HISTORY: A neonatal Thoroughbred foal was presented with rib fractures and left forelimb lameness secondary to dystocia. CLINICAL FINDINGS: The foal developed a head tilt, seizures and watery diarrhoea during hospitalisation and died at 7 days of age. Histological examination of the brain and spinal cord revealed a suppurative meningoencephalomyelitis with vasculitis, and numerous intralesional, gram-negative bacilli. Similar microscopic lesions were noted in the lungs, renal medullary interstitium, and umbilicus. Bacilli in the brain, spinal cord and umbilicus were identified immunohistochemically as Salmonella group B. Salmonella agona was isolated in pure culture from the brain, lung, liver, kidney, and intestine. CONCLUSION: This is the first report of meningoencephalomyelitis and septicaemia due to Salmonella infection in an equine neonate.  相似文献   

Depoliticizing land and water “grabs” in Colombia: the limits of Bonsucro certification for enhancing sustainable biofuel practices     

Theresa Selfa  Carmen Bain  Renata Moreno 《Agriculture and Human Values》2014,31(3):455-468

As concerns heighten over links between biomass production and land grabs in the global south, attention is turning to understanding the role of governance of biofuels systems, whereby decision-making and conduct are not solely determined through government regulations but increasingly shaped by non-state actors, including multi-stakeholder initiatives (MSI). Launched in 2005, Bonsucro is the principal MSI that focuses on sustainability standards for sugar and sugarcane ethanol production. Bonsucro claims that because it is free from government interference and draws on scientific metrics, their standards transcend localized, political–economic contexts. In this paper, we illustrate how the local context shapes the prospects for Bonsucro sustainably certified biofuel production in relation to land and water grabs. To accomplish this, our case focuses on Colombia, which has used a range of national policy mandates to establish itself as one of the larger producers of agrofuels in Latin America. We draw on interviews with stakeholders in the sugar and ethanol industries, paired with an examination of Bonsucro principles on land rights and water use, to illustrate how the sugar industry is framing their participation in Bonsucro, and the effects of the increasing intensification of sugarcane for ethanol production on land and water access for communities. We find that within the context of Colombia, efforts such as Bonsucro provide a veil of legitimacy and authority to a system that is premised on deeply entrenched historical patterns of inequitable land ownership patterns and access to natural resources.  相似文献

Data from the Global Oscillation Network Group (GONG) project and other helioseismic experiments provide a test for models of stellar interiors and for the thermodynamic and radiative properties, on which the models depend, of matter under the extreme conditions found in the sun. Current models are in agreement with the helioseismic inferences, which suggests, for example, that the disagreement between the predicted and observed fluxes of neutrinos from the sun is not caused by errors in the models. However, the GONG data reveal subtle errors in the models, such as an excess in sound speed just beneath the convection zone. These discrepancies indicate effects that have so far not been correctly accounted for; for example, it is plausible that the sound-speed differences reflect weak mixing in stellar interiors, of potential importance to the overall evolution of stars and ultimately to estimates of the age of the galaxy based on stellar evolution calculations.  相似文献

Rates and processes of mineral weathering in soils developed on greywackes and shales in the Southern Uplands of Scotland     

D. C. Bain  D. M. L. Duthie  C. M. Thomson 《Water, air, and soil pollution》1995,85(3):1069-1074

Critical loads of acid deposition are exceeded in parts of the Southern Uplands of Scotland where base saturation in the topmost mineral horizons in many soils developed on greywackes and shales is <10%. Long-term weathering rates calculated by the elemental depletion method from nine soil profiles across a 200 km transect indicate losses of base cations in the range 4–31 meq m^?2a^?1. In every profile the most depleted base cation is Mg which is directly related to the weathering of chlorite which is often present at the 20–40% level in basal horizons but is often completely weathered out in E horizons. The second most depleted base cation is usually K, and this is clearly related to the weathering of mica to a vermiculitic mineral which, in the clay fractions, contains polymeric hydroxyaluminium in the interlamellar space if the soil pH is >4.3. The base cation least depleted is Ca and this is in sharp contrast to current weathering rates calculated from input-output budgets where Ca is the main base cation being exported. This discrepancy may be due to a contribution to the output from easily soluble Ca-bearing minerals (e.g. calcite) in narrow veins and fractures in the bedrock.  相似文献

Effects of a selective serotonin reuptake inhibitor on urine spraying behavior in cats.     

P A Pryor  B L Hart  K D Cliff  M J Bain 《Journal of the American Veterinary Medical Association》2001,219(11):1557-1561

OBJECTIVE: To determine the effectiveness of a readily available selective serotonin reuptake inhibitor (SSRI), fluoxetine hydrochloride, on reducing problem urine spraying in cats. DESIGN: Randomized placebo-controlled double-blind clinical trial. ANIMALS: 17 neutered cats > 1 year old with objectionable urine spraying behavior. Procedure-Owners recorded urine-spraying events for 2 weeks (baseline). Cats that vertically marked a mean of > or = 3 times per week were treated for 8 weeks with fluoxetine or fish-flavored liquid placebo. If urine spraying was not reduced by 70% by weeks 4 through 5, the dosage was increased by 50% for weeks 7 and 8. After discontinuation of treatment at the end of 8 weeks, owners recorded daily urine marks for another 4 weeks. RESULTS: The mean (+/- SE) weekly rate of spraying episodes in treated cats was 8.6 (+/- 2.0) at baseline, decreased significantly by week 2 (1.7 +/- 0.6), and continued to decrease by weeks 7 and 8 (0.4 +/- 0.2). The mean weekly spraying rate of cats receiving placebo was 7.8 (+/- 1.5) at baseline, decreased only slightly during week 1 (5.5 +/- 1.8), and did not decline further. When treatment was discontinued after 8 weeks, the spraying rate of cats that had received treatment varied. The main adverse reaction to the drug was a reduction in food intake, which was observed in 4 of 9 treated cats. CONCLUSIONS AND CLINICAL RELEVANCE: Administration of fluoxetine hydrochloride for treatment of urine spraying in cats can be expected to considerably reduce the rate of urine marking. The frequency of spraying before treatment is predictive of the spraying rate when the drug is discontinued.  相似文献   

Determination of albumin in caprine serum     

M S Bain 《Research in veterinary science》1986,41(1):82-84

Dye-binding techniques using bromocresol green (BCG) and bromocresol purple (BCP) were compared with cellulose acetate electrophoresis for the determination of caprine serum albumin. When a caprine standard was used the electrophoretic values showed little difference from those obtained with BCG. However, when a bovine standard or BCP were used, there were differences. Bias was detected between the values determined with bovine and caprine albumin standards owing to the different absorbances of the dye-protein mixtures. Using BCG, a closer correlation was obtained between the electrophoretic and caprine standard values than between the electrophoretic and bovine standard values, but with BCP the reverse was true although these differences were not significant. BCP was considered a less suitable dye than BCG for routine analysis because of low absorbance changes and the resulting poor precision.  相似文献   

Canine histiocytic ulcerative colitis   总被引：1，自引：0，他引：1  

RK CHURCHER  ADJ WATSON 《Australian veterinary journal》1997,75(10):710-713

Objective To assess prevalence, breed predilection, response to therapy and prognosis of canine histiocytic ulcerative colitis (CHUC).
Design A retrospective study of cases of CHUC seen at Sydney University Veterinary Teaching Hospital (SUVTH) over a 20-year period (1975 -1994).
Procedure Case records of all dogs in which colitis was suspected were reviewed. Dogs were diagnosed with CHUC based on colonorectal biopsy and histopathological examination.
Results CHUC was diagnosed in 8 of 57 dogs presented for colitis. All affected dogs were Boxers and six were female. Dogs with milder clinical signs showed moderately good response to therapy. Four dogs were still alive 1 to 7 years after diagnosis. Three dogs were euthanased, one for reasons other than CHUC, and one was lost to follow-up.
Conclusions Young boxer dogs with relatively mild signs of CHUC may respond moderately well to medical and dietary therapy with fair prognosis. Euthanasia early in the course of the disease may be unwarranted. Prevalence may be increasing within the SUVTH referral population.  相似文献
