Three adult Pomeranian dogs, full siblings from 2 litters, were diagnosed with primary hypoadrenocorticism following onset of hypoadrenal crisis. Review of the family history revealed the dogs’ maternal grandmother also had hypoadrenocorticism. All 4 dogs were pedigree-certified by the American Kennel Club. An inherited basis for hypoadrenocorticism is proposed in these Pomeranian dogs. 相似文献

Background
Bluetongue virus (BTV) is an insect-transmitted virus, which causes bluetongue disease (BT) in sheep and a fatal hemorrhagic infection in North American white-tailed deer. However, in cattle the disease is typically asymptomatic and no overt clinical signs of disease appear to be associated with BTV infection. Serological evidence and isolation of different BTV serotypes have been reported in Sudan, however, no information is currently available in regard to previous exposure of Sudanese livestock to BTV infection in East Darfur State, Sudan.Aims
To determine the prevalence of BTV antibodies and to identify the potential risk factors associated with BTV infection among cattle in East Darfur State, Sudan.Methods
A total of 224 blood samples were collected randomly from five localities in East Darfur State, Sudan. The serum samples were screened for detection of BTV-specific immunoglobulin G (IgG) antibodies using a competitive enzyme-linked immunosorbent assay (c-ELISA).Results
Serological evidence of BTV infection was observed in 150 out of 224 animals accounting for a 67% prevalence rate among cattle in East Darfur State. Older cattle (>2 years of age) were six times more likely to be infected with BTV (OR = 6.62, CI = 2.87-15.26, p-value = 0.01). Regarding animal source (contact with other herds) as a risk factor, it was shown that cattle purchased from market or introduced from other herds were 3 times at higher risk of being infected with BTV (OR = 3.87, CI = 1.07-13.87, p value = 0.03). Exposure of cattle to the insect vector increased the risk of contracting BTV infection by six times compared to non-exposed cattle (OR = 6.44, CI = 1.53-27.08, p value = 0.01).Conclusion
The present study indicated that age, animal source and the intensity of the insect vector are influential risk factors for BTV infection in cattle in the Darfur region. Surveillance for BTV infection should be extended to include other susceptible ruminants and to study the distribution of the insect vectors to better predict and respond to a possible BTV outbreak in the State of East Darfur, Sudan. 相似文献4.

OBJECTIVE: To compare effects of short-term administration of a soy diet with those of a soy-free diet on serum thyroid hormone concentrations in healthy adult cats. ANIMALS: 18 healthy adult cats. PROCEDURE: Cats were randomly assigned to receive either a soy or soy-free diet for 3 months each in a crossover design. Assays included CBC, serum biochemical profile, thyroid hormone analysis, and measurement of urinary isoflavone concentrations. RESULTS: Genistein, a major soy isoflavone, was identified in the urine of 10 of 18 cats prior to dietary intervention. Compared with the soy-free diet, cats that received the soy diet had significantly higher total thyroxine (T4) and free T4 (fT4) concentrations, but unchanged total triiodothyronine (T3) concentrations. The T3/fT4 ratio was also significantly lower in cats that received the soy diet. Although the magnitudes of the increases were small (8% for T4 and 14% for fT4), these changes resulted in an increased proportion of cats (from 1/18 to 4/18) that had fT4 values greater than the upper limit of the laboratory reference range. There was no significant effect of diet on any other measured parameter. CONCLUSIONS AND CLINICAL RELEVANCE: Short-term administration of dietary soy has a measurable although modest effect on thyroid hormone homeostasis in cats. Increase in T4 concentration relative to T3 concentration may result from inhibition of 5'-iodothyronine deiodinase or enhanced T3 clearance. Soy is a common dietary component that increases serum T4 concentration in cats. 相似文献

The goal of this randomized, double‐blind study was to compare the effects of feeding a low carbohydrate, high protein diet versus a maintenance diet in a group of cats with diabetes mellitus treated with insulin glargine twice daily. All cats with naturally occurring diabetes mellitus not currently treated with insulin glargine or diabetogenic drugs or being fed a low carbohydrate, high protein diet were eligible for inclusion. Baseline testing included a physical examination, complete blood count, serum biochemistry profile, urinalysis and urine culture, serum thyroxine concentration, and serum fructosamine concentration. All cats were treated with insulin glargine (starting dose of 0.25 U/kg) twice daily. Insulin was adjusted as needed for glucose regulation. Cats were randomized to receive either a low carbohydrate, high protein diet or a feline maintenance diet. Re‐evaluations were performed on all cats at weeks 1, 2, 4, 6 and 10, and included an assessment of clinical signs, physical examination, 12‐h blood glucose curve, and serum fructosamine concentrations. Changes in continuous variables over the course of the study were analyzed using analysis of variance with repeated measures. p < 0.05 was considered statistically significant. Ten cats have completed the study. There were no significant differences between diet groups at baseline for age, gender, weight, body condition score, serum glucose or fructosamine concentrations. Although there was not a significant difference over time in clinical signs, insulin doses, or peak or nadir glucose concentrations between diet groups, diet did have a significant effect on serum fructosamine concentrations (p = 0.01). Six of the 10 cats that have completed the study achieved complete remission by the end of the study period, with no statistical difference between diets. The study's results indicate that diet can have significant effects on glucose regulation in cats receiving insulin glargine for treatment of feline diabetes mellitus. 相似文献

Bronchoscopy is a useful tool in the evaluation and management of canine and feline respiratory diseases. Diagnostic indications include the evaluation of structural diseases (tracheobronchial collapse, stricture, intraluminal mass); inflammatory conditions (chronic bronchitis, pneumonia); and traumatic injuries. Several airway-sampling techniques are available with bronchoscopy; bronchoalveolar lavage has proved to be the most satisfactory specimen-collection technique. Therapeutic indications of bronchoscopy at this time in veterinary medicine are mainly limited to foreign body removal. As advances are made in veterinary bronchopulmonary medicine, other therapeutic applications of the bronchoscope may be realized. 相似文献

The goals of this study were to compare the efficacy of once-daily administered Glargine insulin to twice-daily administered Lente insulin in cats with diabetes mellitus and to describe the use of a high-protein, low-carbohydrate diet designed for the management of diabetes mellitus in cats. All cats with naturally occurring diabetes mellitus were eligible for inclusion. Baseline testing included a physical examination, serum biochemistry, urinalysis and urine culture, serum thyroxine concentration, and serum fructosamine concentration. All cats were fed the high-protein, low-carbohydrate diet exclusively. Cats were randomized to receive either 0.5 U/kg Lente insulin q12h or 0.5 U/kg Glargine insulin q24h. Re-evaluations were performed on all cats at weeks 1, 2, 4, 8, and 12, and included an assessment of clinical signs, physical examination, 16-hour blood glucose curve, and serum fructosamine concentrations. Thirteen cats completed the study (Lente, n = 7, Glargine, n = 6). There was significant improvement in serum fructosamine and glucose concentrations in all cats but there was no significant difference between the 2 insulin groups. Four of the 13 cats were in complete remission by the end of the study period (Lente, n = 3; Glargine, n = 1). The results of the study support the use of once-daily insulin Glargine or twice-daily Lente insulin in combination with a high-protein, low-carbohydrate diet for treatment of feline diabetes mellitus. 相似文献
