A bitch was inoculated subcutaneously and intramuscularly with Neospora caninum tachyzoites on Day 35 of pregnancy. Eight pups were born 28 days later. Five pups became ill and necropsies were performed before 20 days of age. Three pups and the bitch remained clinically normal for 7 weeks after parturition when they were intramuscularly injected with 40 mg kg-1 methylprednisolone acetate weekly to activate chronic N. caninum infection. Necropsies were performed 48, 17, 18, and 18 days respectively after administration of corticosteroids. Hepatic necrosis, pneumonia, encephalomyelitis, and myonecrosis were the main changes seen in these dogs.  相似文献

The clinical and radiographic signs of panosteitis in seven dogs are described and also the histological and fluorochrome-labelled appearance of the lesions in one of them. The condition was seen in three immature German Shepherd dogs, three immature mongrels, of which two were littermates, and an adult Doberman Pinscher which presented with lesions of its metacarpus.  相似文献

Ketamine in dogs   总被引:1,自引:0,他引:1  
The cardiopulmonary consequences of ketamine (10 mg/kg, IV) were evaluated in 18 dogs. Heart rate, cardiac output, systemic blood pressure, left ventricular work, oxygen transport, oxygen consumption, carbon dioxide production, and core temperature increased. Breathing rate, minute ventilation, and arterial partial pressure of oxygen transiently decreased. Arterial partial pressure of carbon dioxide, alveolar-arterial oxygen gradient, and venous admixture transiently increased. The duration of action of ketamine for surgical anesthesia was short. Muscle tone and salivation were excessive, and spontaneous muscular activity was prominent.  相似文献
