A case of bilateral, upper urinary tract infection caused by haemolytic E coli in a female Birman cat is presented. Ultrasonographic examination of the kidneys documented changes in size, outline, echogenicity and architecture. Ultrasound guided fine needle aspiration of fluid from the renal pelvis was used to make the diagnosis. Fluid was submitted for culture and sensitivity and based on the results, antimicrobial therapy was initiated. The treatment was monitored over a 406-day follow-up period. Despite extensive treatment with specific antibiotics and supportive therapy, recurrence of urinary tract infection occurred. 相似文献

Fructosamines are glycated serum proteins that reflect long-term serum glucose concentrations in humans and several animal species. In the present study, blood samples were drawn from three populations of diabetic cats: untreated diabetic cats with clinical symptoms prevailing only a few days (n = 1), untreated diabetic cats with symptoms lasting more than two weeks (n = 6) and clinically well stabilised diabetic cats receiving insulin twice daily which showed no signs of disease (n = 4). All untreated diabetic cats showed elevated fructosamine measurements. Based on fructosamine measurements, clinically well stabilised diabetic cats could be subdivided further according to the degree of glycaemic control. Diabetic cats with satisfactory glycaemic control revealed fructosamine concentrations within or close to the reference range (146 to 271 umol/litre), whereas fructosamine concentrations above 400 umol/litre indicated insufficient glycaemic control. This study suggests that the fructosamine assay reflects persistently elevated serum glucose concentrations in cats and is a useful parameter for diagnosing and monitoring diabetes mellitus in cats. 相似文献

The aims of this study were to evaluate the ability of diagnostic methods to detect naturally occurring Cheyletiella infestation in dogs, and to quantify and relate the number of mites and eggs present to clinical signs. Privately owned dogs with skin problems were eligible for inclusion in the study. Four diagnostic tests were performed on each dog in the following order: tape impression, hair plucking, skin scraping and vacuum cleaning. Dogs with positive test results for Cheyletiella infestation in at least one of the tests under evaluation were included in the study (n=27). The severity of pruritus and scaling was graded on a four-point fixed scale. The diagnostic findings in vacuum cleaning samples provided a semiquantitative measure of the grade of infestation. The vacuum cleaning test gave a positive test result in all dogs and was significantly more efficient than the other tests evaluated (P<0.01). The number of diagnostic findings varied considerably among the different vacuum samples. No significant relationship between the number of diagnostic findings and severity of clinical signs was detected. 相似文献

A five-year-old intact male rottweiler was presented with a history of episodic weakness and mild generalised seizures. A tentative diagnosis of an insulin-secreting tumour in the pancreas was made based on fasting hypoglycaemia with concomitant hyperinsulinaemia and a subnormal fructosamine value. The diagnosis was confirmed by exploratory coeliotomy, intravenous infusion of methylene blue, histopathology and immuno-histochemical analysis of suspected neoplastic tissue. Fructosamine assays are traditionally used for monitoring the metabolic status of diabetics where a single elevated measurement reflects persistent hyperglycaemia. This report suggests that a single low measurement of fructosamine may indicate persistent hypoglycaemia and may be helpful, in conjunction with an insulin measurement, in the diagnosis of insulin-secreting tumours. 相似文献
