Fatal extraintestinal toxoplasmosis in a young male cat with enlarged mesenteric lymph nodes     

Tamara M. Cohen  Shauna Blois  Andrew R. Vince 《The Canadian veterinary journal. La revue veterinaire canadienne》2016,57(5):483-486

A 22-month-old indoor/outdoor neutered male domestic short-haired cat had a history of progressive lethargy, vomiting, and decreased appetite. Abdominal ultrasound revealed an irregular hyperechoic mass in the mid-abdomen. He was unresponsive to symptomatic medical management and was euthanized after 3 days of hospitalization. A diagnosis of disseminated extraintestinal toxoplasmosis was made based on the finding of intracytoplasmic protozoan parasites on histopathological examination of mesenteric lymph nodes, hepatic and intestinal samples, and on immunohistochemistry.  相似文献   

Diagnosis and treatment of presumptive postobstructive pulmonary edema in a Florida panther (Puma concolor coryi).

A free-ranging, adult male Florida panther (Puma concolor coryi) was immobilized and evaluated for hematuria following routine capture. Prior to anesthetic recovery, the panther was fitted with a telemetry collar. After an initially quiet recovery, the panther began thrashing in the transport cage, and was again immobilized. Pink foam was evident from the nostrils, and crackles were ausculted over the chest, indicating pulmonary edema. Postobstructive pulmonary edema was diagnosed based on history, clinical signs, radiographic evaluation, and blood gas analysis. The animal was treated intensively for several hours with diuretics, oxygen, and manual ventilation. The panther responded rapidly to therapy and was released back into the wild 48 hr after presentation. Postobstructive pulmonary edema, also called negative-pressure pulmonary edema, may be underrecognized in veterinary medicine. In this case, the telemetry collar, in conjunction with anesthetic recovery in a small transport crate, may have contributed to tracheal obstruction. Wildlife veterinarians and biologists should be aware of the risk of airway obstruction when placing tracking collars, and animals should be continuously monitored during anesthetic recovery to ensure the presence of a patent airway.  相似文献   

Landscape ecology of <Emphasis Type="Italic">Phragmites australis</Emphasis> invasion in networks of linear wetlands     

Mathieu Maheu-Giroux  Sylvie de Blois 《Landscape Ecology》2007,22(2):285-301

The interaction between landscape structure and spatial patterns of plant invasion has been little addressed by ecologists despite the new insights it can provide. Because of their spatial configuration as highly connected networks, linear wetlands such as roadside or agricultural ditches, can serve as corridors facilitating invasion at the landscape scale, but species dynamics in these important habitats are not well known. We conducted a landscape scale analysis of Phragmites australis invasion patterns (1985–2002 and 1987–2002) in two periurban areas of southern Québec (Canada) focusing on the interaction between the network of linear wetlands and the adjacent land-uses. Results show that, at the beginning of the reference period, the two landscapes were relatively non-invaded and populations occurred mostly in roadside habitats which then served as invasion foci into other parts of the landscape. The intrinsic rates of increase of P. australis populations in linear anthropogenic habitats were generally higher than those reported for natural wetlands. Riparian habitats along streams and rivers were little invaded compared to anthropogenic linear wetlands, except when they intersected transportation rights-of-way. Bivariate spatial point pattern analysis of colonization events using both Euclidian and network distances generally showed spatial dependence (association) to source populations. An autologistic regression model that included landscape and edaphic variables selected transportation rights-of-way as the best predictor of P. australis occurrence patterns in one of the landscapes. Given the high invasion rates observed, managers of linear wetlands should carefully monitor expansion patterns especially when roads intersect landscapes of conservation or economic value.  相似文献   

ULTRASONOGRAPHIC, GROSS, AND HISTOLOGIC EVALUATION OF A TENDINITIS DISEASE MODEL IN THE HORSE     

Gareth H.  Spurlock  DVM  MS  Shauna L.  Spurlock  DVM  MS  George A.  Parker  DVM 《Veterinary radiology & ultrasound》1989,30(4):184-188

Collagenase-induced lesions of the superficial digital flexor tendon were monitored using diagnostic ultrasound and subsequently compared with gross and microscopic findings. The postinjury sonograms demonstrated hypoechoic or anechoic areas corresponding to areas of hemorrhage and necrosis. The size of the lesion increased and the echogenicity decreased with increasing units of collagenase injected into the tendon. As postinjury time increased, echogenicity increased, which corresponded to fibrous-tissue invasion and collagen deposition. The extent of tendon injury produced correlated with the amount of collagenase injected into the tendon. Diagnostic ultrasound is useful in evaluating injury and healing in collagenase— induced tendinitis.  相似文献

Thromboelastography platelet mapping in healthy dogs using 1 analyzer versus 2 analyzers     

Shauna L. Blois  Amrita Banerjee  R. Darren Wood  Fiona M. Park 《Canadian journal of veterinary research》2013,77(3):231-236

The objective of this study was to describe the results of thromboelastography platelet mapping (TEG-PM) carried out using 2 techniques in 20 healthy dogs. Maximum amplitudes (MA) generated by thrombin (MA_thrombin), fibrin (MA_fibrin), adenosine diphosphate (ADP) receptor activity (MA_ADP), and thromboxane A₂ (TxA₂) receptor activity (stimulated by arachidonic acid, MA_AA) were recorded. Thromboelastography platelet mapping was carried out according to the manufacturer’s guidelines (2-analyzer technique) and using a variation of this method employing only 1 analyzer (1-analyzer technique) on 2 separate blood samples obtained from each dog. Mean [± standard deviation (SD)] MA values for the 1-analyzer/2-analyzer techniques were: MA_thrombin = 51.9 mm (± 7.1)/52.5 mm (± 8.0); MA_fibrin = 20.7 mm (± 21.8)/23.0 mm (± 26.1); MA_ADP = 44.5 mm (± 15.6)/45.6 mm (± 17.0); and MA_AA = 45.7 mm (± 11.6)/45.0 mm (± 15.4). Mean (± SD) percentage aggregation due to ADP receptor activity was 70.4% (± 32.8)/67.6% (± 33.7). Mean percentage aggregation due to TxA₂ receptor activity was 77.3% (± 31.6)/78.1% (± 50.2). Results of TEG-PM were not significantly different for the 1-analyzer and 2-analyzer methods. High correlation was found between the 2 methods for MA_fibrin [concordance correlation coefficient (r) = 0.930]; moderate correlation was found for MA_thrombin (r = 0.70) and MA_ADP (r = 0.57); correlation between the 2 methods for MA_AA was lower (r = 0.32). Thromboelastography platelet mapping (TEG-PM) should be further investigated to determine if it is a suitable method for measuring platelet dysfunction in dogs with thrombopathy.  相似文献

Crafting an Antidote to Fast Fashion: The Case of Toronto's Independent Fashion Design Sector     

Deborah Leslie  Shauna Brail  Mia Hunt 《Growth and change》2014,45(2):222-239

The fashion industry has undergone a profound transformation in business practices and production systems over the past several decades. These shifts include the globalisation of production chains and the emergence of a new model of “fast fashion.” This paper investigates the response of independent fashion designers in Toronto, Canada to the growing competition posed by fast fashion. It identifies a number of strategies utilised by designers to compete, arguing that they are increasingly adopting a new model of “slow fashion,” which opens up possibilities for forging locally and ethically based relationships in the fashion sector.  相似文献
