AN IN-VITRO TECHNIQUE FOR STUDYING FLEECE-ROT AND FLY STRIKE IN SHEEP   总被引：1，自引：0，他引：1  

G.C. Merritt  J.E. Watts 《Australian veterinary journal》1978,54(11):513-516

Fleece-rot was experimentally induced in-vitro by wetting and incubating Merino wool samples embedded in serum-agar. Gravid Lucilia cuprina were readily-attracted to these wool culture plates to oviposit. Where serum was freely available to newly-hatched larvae, fly strike and larval development ensued. Using this technique, fleece-rot and oviposition were found to be markedly influenced by the availability of protein and by bacterial activity, particularly that of Pseudomonas spp. The results indicated that odours emanating from wool culture plates containing the latter species played an important role in oviposition. Furthermore, these events varied according to the type of fleece selected, and could be prevented by the addition of a bactericide.  相似文献   

Septic epiglottic chondritis with abscessation in 2 young Thoroughbred racehorses     

Infernuso T  Watts AE  Ducharme NG 《The Canadian veterinary journal. La revue veterinaire canadienne》2006,47(10):1007-1010

Septic epiglottic chondritis with abscessation diagnosed in 2 Thoroughbred racehorses. Infected cartilage removed videoendoscopically followed by systemic antibiotics. The infectious process was successfully controlled, but permanent dorsal displacement of the soft palate (DDSP) with a shortened, deformed epiglottic cartilage developed. Surgery for the DDSP using bilateral partial sternothyroidectomy or laryngeal tie-forward failed.  相似文献

Digital hypothermia inhibits early lamellar inflammatory signalling in the oligofructose laminitis model     

van Eps AW  Leise BS  Watts M  Pollitt CC  Belknap JK 《Equine veterinary journal》2012,44(2):230-237

Reasons for performing study: The pathophysiological events inhibited by prophylactic digital hypothermia that result in reduction of the severity of acute laminitis are unknown. Objectives: To determine if digital hypothermia inhibits lamellar inflammatory signalling during development of oligofructose (OF) induced laminitis. Methods: Fourteen Standardbred horses were given 10 g/kg bwt OF by nasogastric tube with one forelimb (CRYO) continuously cooled by immersion in ice and water and one forelimb (NON‐RX) at ambient temperature. Lamellae were harvested prior to the onset of lameness (24 h post OF administration, DEV group, n = 7) or at the onset of lameness (OG1 group, n = 7). Lamellar mRNA was purified and cDNA produced for real time‐quantitative PCR analysis of mRNA concentrations of cytokines (IL‐6, IL‐1β, IL‐10), chemokines (CXCL1, CXCL6, CXCL8/IL‐8, MCP‐1, MCP‐2), cell adhesion molecules (ICAM‐1, E‐selectin), COX‐2 and 3 housekeeping genes. Data were analysed (NON‐RX vs. CRYO, NON‐RX vs. archived control [CON, n = 7] lamellar tissue) using nonparametric tests. Results: Compared with CON, the OG1 NON‐RX had increased (P<0.05) lamellar mRNA concentrations of all measured mediators except IL‐10, IL‐1β and MCP‐1/2, whereas only CXCL8 was increased (P<0.05) in DEV NON‐RX. Within the OG1 group, CRYO limbs (compared with NON‐RX) had decreased (P<0.05) mRNA concentrations of the majority of measured inflammatory mediators (no change in MCP‐1 and IL‐10). Within the DEV group, mRNA concentrations of CXCL‐1, ICAM‐1, IL‐1β, CXCL8 and MCP‐2 were decreased (P<0.05) and the anti‐inflammatory cytokine IL‐10 was increased (compared with NON‐RX limbs; P<0.05). Conclusions: Digital hypothermia effectively blocked early lamellar inflammatory events likely to play an important role in lamellar injury including the expression of chemokines, proinflammatory cytokines, COX‐2 and endothelial adhesion molecules. Potential relevance: This study demonstrates a potential mechanism by which hypothermia reduces the severity of acute laminitis, and may help identify molecular targets for future laminitis intervention.  相似文献   

Hindlimb laminar inflammatory response is similar to that present in forelimbs after carbohydrate overload in horses     

Leise BS  Faleiros RR  Watts M  Johnson PJ  Black SJ  Belknap JK 《Equine veterinary journal》2012,44(6):633-639

Reasons for performing study: A significant proinflammatory response is known to occur in the forelimb lamina after carbohydrate administration. As the hindlimbs are often less affected by laminitis compared with the forelimbs, we assessed hindlimb inflammatory response in the early stages of carbohydrate‐induced laminitis to determine whether differences in the response existed. Objective: To determine whether a similar proinflammatory response occurs in the hindlimb laminae to that previously reported for the forelimb. Methods: Archived laminar samples from 12 horses administered 17.6 g of starch (85% corn starch, 15% wood flour)/kg bwt via nasogastric tube that were anaesthetised either after developing a temperature >38.9°C (DEV; n = 6) or at the onset of Obel grade 1 lameness (OG1; n = 6) were used in addition to 6 control horses (CON) that were anaesthetised 24 h after administration of water. Real‐time quantitative polymerase chain reaction for selected proinflammatory mediators and MAC387 immunohistochemistry were performed. The data were analysed nonparametrically to compare groups. Results: Increases in laminar MAC387‐positive leucocytes and laminar messenger ribonucleic acid (mRNA) concentrations (P<0.05) for interleukin‐1β, interleukin‐6, cyclo‐oxygenase‐2, chemokine (C‐X‐C motif)ligand (CXCL)1 and CXCL8 were present in both fore‐ and hindlimb laminae from horses with OG1 lameness. Both CXCL1 and CXCL8 were also increased in forelimb and hindlimb laminae in the DEV horses. Conclusions: Administration of carbohydrate resulted in a similar inflammatory response in the hindlimb laminae to that previously reported for the forelimb laminae. These findings suggest that other factors, such as weightbearing, may play an important role in the development of laminitis after a systemic inflammatory condition develops. Potential relevance: Evidence of inflammation in the hindlimb laminae suggests that the hindfeet should be addressed in the septic horse at risk for laminitis; however, laminitis is often less severe in the hindlimbs due to other factors, such as weightbearing and hoof angle.  相似文献

Wetting of agricultural soil measured by a simplified capillary rise technique     

G. P. Matthews    C. W. Watts    D. S. Powlson    J. C. Price  & W. R. Whalley 《European Journal of Soil Science》2008,59(4):817-823

We describe the use of a capillary rise method to measure the wettability of 10 samples of agricultural soil from Rothamsted long-term experimental sites. The samples have very similar clay contents, but organic carbon (C) contents range from 11.5 to 31.2 g kg⁻¹. Their wetting rates were interpreted by an improved method of data analysis, consistent with the Washburn equation, and showed an increase in the effective contact angle between the water meniscus and the soil with increasing C content. This corresponds to a decrease in wettability with increasing C content, and accords with other results reported in the literature. By contrast with water, we found that capillary rise for n -hexane into soil did not depend on the soil's bulk density or C content. A priori calculations of the expected wetting rates from fluid properties and an effective hydraulic radius estimated by other methods gave magnitudes and trends that agreed with our experimental data. The results show that estimates of effective hydraulic radius can provide a useful approximation for characterizing soil wetting, but that further modelling should be carried out.  相似文献
