摘要:

ABSTRACTSix cases of neosporosis in dogs were diagnosed on the basis of clinical signs, serology and immunohistochemistry. The brains and spinal cords, at several levels, and various other tissues were examined usinganti‐Neospora caninumserum by an immunoperoxidase technique. Parasite density varied markedly from case to case. Although found most consistently in the cerebrum, parasites were distributed throughout the central nervous system (CNS), both within the grey and white matter and within nerve roots. Clinical signs were not related to the position of parasites. Tissue cysts were found infrequently in all areas of the CNS, but not in other tissues. Parasite density was not related to the age of the dog or whether treatment had been given. However, with the exception of the only adult dog examined, more CNS parasites were found in dogs with a longer duration of illness and with higher antibody titres. Tachyzoites were present in skeletal muscles, in the muscularis of the oesophagus, in heart, lung and, less frequently, liver, and rarely in the adrenal gland, thyroid gland and uterus; no clinical signs were seen resulting from damage to these organs. Parasites were not observed in lymphoid tissue. In visceral organs, parasites were most widely distributed in peracute cases. For post mortem diagnosis of neosporosis, the CNS, particularly the cerebrum, is the optimum tissue to examine but parasites may also be found in many other tissues, especially in acute cases. Muscle biopsy of appropriate muscles (as suggested by the clinical signs) provides the possibility of a definitive pre‐mortem diagno

摘要:

ABSTRACTThirty cats with untreated hyperthyroidism were blood sampled and their calcium homeosta‐tic mechanisms and renal function assessed. The results were compared with those obtained from 38 age‐matched control cats. The hyperthyroid group of cats were found to have significantly lower blood ionised calcium and plasma creatinine concentrations and significantly higher plasma phosphate and parathyroid hormone concentrations. Hyperparathyroidism occurred in77per cent of hyperthyroid cats, with parathyroid hormone concentrations reaching up to 19 times the upper limit of the normal range. The aetiology, significance and reversibility of hyperparathyroidism in feline hyperthyroidism remains to be established but could have important implications for both bone strength and renal funct

ABSTRACTThis report describes the presenting features, radiographic changes, biochemical alterations and clinical progress of two kittens, from separate litters, which were found to have a growth plate disturbance initially diagnosed and treated as vitamin D3‐dependent rickets, but subsequently suspected to be a metaphyseal chondrodysplasi

摘要:

ABSTRACTA seven‐year‐old entire male Irish setter was presented because of a neck mass, prolapse of the third eyelid and apparent drooping of the upper eyelid. Historical findings included increased appetite as well as polyuria and polydipsia for about two weeks. The most remarkable findings on physical examination were right‐sided Horner's syndrome, pre‐scapular lymphadenopathy and a large, ventral cervical mass. Lateral cervical radiographs showed a large, soft tissue opacity surrounding the trachea and retropharyngeal area which was causing displacement and narrowing of the cervical trachea and oesophagus. Results of thyroid testing suggested hyperthyroidism. At necropsy, a large, invasive tumour was identified in the ventral cervical region and multiple metastases of various sizes were detected in the lungs. Histopathological examination of the tumour revealed follicular thyroid carcinoma and confirmed widespread pulmonary met

摘要:

ABSTRACTCanine angiostrongylosis was diagnosed in a whippet with typical signs of respiratory and circulatory distress. SubclinicalAngiostrongylus vasoruminfections were also demonstrated in two other whippets belonging to the same owner. All three dogs were given standard anthelmintic levamisole treatment combined with corticosteroids. Two days after initiation of treatment, one of the subclinically infected dogs developed severe hypovolaemic shock that required intravenous fluid therapy and corticosteriods to save its life. The shock is believed to have been caused by an anaphylactic reaction triggered by the rapid release of a large amount of worm antigen in the blood due to the rapid death of adult worms by levamisole. Thus, dog owners should be instructed to monitor dogs undergoing levamisole treatment againstA vasorum.Alternatives to levamisole treatment of canine angiostrongylosis should be considered.

摘要:

ABSTRACTA 12‐year‐old male shih tzu dog was diagnosed as having a calcifying epithelial odontogenic tumour. One and a half years prior to presentation, a mass was noticed on the right mandible by the owners. Radiography revealed irregular, faintly radiopaque material within the tumour. A right hemimandibulectomy was performed, based on the clinical diagnosis of osteosarcoma. Histopathological evaluation of the mandibular mass showed that it was composed of a polyhedral odontogenic epithelial cell nest, fibrous stroma, homogeneous eosinophilic material and rounded calcifying material. The eosinophilic material was visualised by staining with Congo red, and observed under green birefringence by polarisation microscopy. Although the tumour had not recurred 12 months after surgery, the dog was euthanased because of aspiratic pharyngitis. The literature on the clinical behaviour of calcifying epithelial odontogenic tumours in dogs and cats is revie
