OBJECTIVE: To determine effects of lufenuron treatment in cats on the establishment and course of Microsporum canis infection following exposure to infected cats. DESIGN: Experimental trial. ANIMALS: 24 healthy juvenile domestic shorthair cats. PROCEDURE: 8 cats were given lufenuron PO (133 mg/cat/mo, equivalent to a dose of 100 to 130 mg/kg [45 to 59 mg/lb] at the beginning of the study and 25 to 35 mg/kg [11 to 16 mg/lb] at the end of the study), and 8 were given lufenuron SC (40 mg every 6 months). The remaining 8 were used as untreated control cats. After 4 months, cats were challenged by the introduction of cats with mild, experimentally induced M canis infection into the rooms where cats were housed. Extent of resulting infections in the na?ve cats was monitored for 22 weeks by physical examination and fungal culture. RESULTS: All lufenuron-treated and control cats became infected with M canis. Cats treated with lufenuron had significantly lower infection scores, compared with control cats, during the early weeks following exposure, and there was a more prolonged initial progression phase of the infection. Once infections reached peak intensity, they resolved over similar periods in lufenuron-treated and control cats. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggested that oral or SC administration of lufenuron to cats, at the dosages used and under the conditions of this study, did not prevent establishment of dermatophytosis following exposure to infected cats. Infection was established more slowly among cats treated with lufenuron, but once established, infection resolved in approximately the same amount of time in lufenuron-treated as in control cats.  相似文献

proPlant expert.com – an online consultation system on crop protection in cereals,rape, potatoes and sugarbeet*     

M. Newe  H. Meier  A. Johnen  T. Volk 《EPPO Bulletin》2003,33(3):443-449

The internet‐based system proPlant expert.com assists farmers in making field‐specific decisions on fungicide and growth regulator application in cereals, insecticide and growth regulator application in rape, and fungicide application in potatoes and sugarbeet. Any consultation is based on both agricultural data and weather reports drawn from official meteorological services. Together with information on the infestation level, the system processes this data to develop a recommendation on the application of a specific plant protection product, if necessary. Farmers and consultancies have been using the service in Germany and other European countries since 2001. Before starting the service in other countries, parts of the software had to be altered to meet the specific requirements of our partners outside Germany.  相似文献

Post‐transplant malignant neoplasia associated with cyclosporine‐based immunotherapy: prevalence,risk factors and survival in feline renal transplant recipients          下载免费PDF全文

C. Wormser  A. Mariano  E. S. Holmes  L. R. Aronson  S. W. Volk 《Veterinary and comparative oncology》2016,14(4):e126-e134

The study objective was to compare the prevalence of malignant neoplasia in feline renal transplant recipients (n = 111) with a control population of cats that did not receive transplantation (n = 142); and to determine whether the development of post‐transplant malignant neoplasia (PTMN) affects long‐term survival. Twenty‐five (22.5%) renal transplant recipients were diagnosed with PTMN, and of those 14 (56%) were diagnosed with lymphoma. The overall survival time in cats that developed PTMN following renal transplantation (median 646 days, IQR 433–1620 days) was not significantly different from the survival time in cats that did not develop PTMN (median 728 days, IQR 201–1942 days), although median survival after diagnosis of PTMN was only 13 days. Six control cats (4.2%) were diagnosed with malignant neoplasia. Compared to the control population, transplant cats had a 6.6 times higher odds of developing malignant neoplasia and a 6.7 times higher odds of developing lymphoma.  相似文献

Incidence rate of musculoskeletal injuries and determinants of time to recovery in young Australian Thoroughbred racehorses     

N Cogger  DL Evans  DR Hodgson  SW Reid  N Perkins 《Australian veterinary journal》2008,86(12):473-480

Objective To describe the incidence rate of musculoskeletal (MS) injuries and investigate the factors that influence recovery from MS injury in young Thoroughbred horses in Australia. Methods Training and injury data were collected at fortnightly intervals from 14 trainers in New South Wales. Incidence rates were calculated for initial injuries stratified by age‐class and sex. Survival analysis methods were used to investigate the time to recovery after the first MS injury (measured as a start in a race or barrier trial). Results For the 248 racehorses enrolled, there were 428 injuries recorded; 2‐year‐olds were 2.99‐fold more likely than 3‐year‐olds to sustain an MS injury. The cumulative percentage of horses that had recovered within 6 months was 55%. The time to recovery was longest in horses whose fast gallop speed prior to injury was < 890 m/min. Conclusion This study supports the finding that shin soreness is the most common MS injury in young Australian Thoroughbreds. There was an increased rate of MS injury in 2‐year‐olds compared with 3‐year‐olds. However, it was impossible to determine if the increased risk in 2‐year‐olds was related to age, the start of training or a combination of both. The study also found that horses performing at higher exercise speeds prior to injury were more likely to recover. There was a significant effect of trainer, suggesting that other factors related to trainer may influence the time to the recovery. Additional research is required to understand the determinants of time to recovery.  相似文献

Variable-rate fungicide spraying in real time by combining a plant cover sensor and a decision support system     

K.-H. Dammer  H. Thöle  T. Volk  B. Hau 《Precision Agriculture》2009,10(5):431-442

In recent years, real-time technology has been introduced into the practice of spraying variable fungicide rates in cereal fields. Plant parameters for characterising heterogeneous plant growth such as biomass or plant surface area can be indirectly detected by the sensor CROP-Meter. The sensor signal is correlated with the Leaf Area Index, which can be used to adapt the application rate. However, this relatively simple method of controlling variable-rate fungicide application does not take into account the differences in disease distribution. In practice, decision support systems such as proPlant expert.classic can provide information about disease infection probabilities, application time, fungicide products and application rates for uniform spraying. A prototype of the system proPlant expert.precise was developed to estimate infection risks from fungal diseases using weather and field-specific data for up to three management areas with different yield expectations. The system also considers economic factors such as expected yield and costs of the fungicide products in generating a spraying map with different fungicide dosages. The information from the CROP-Meter (sensor) and from the decision support system proPlant expert.precise (map) was combined to provide a real-time spraying system with map overlay. The system was tested in 2007 in three winter wheat fields. Compared with conventional uniform spraying the CROP-Meter with map overlay treatment resulted in up to 32.6% fungicide savings (CROP-Meter versus uniform: up to 20.3%). There was no yield reduction on average when the sensor-controlled spraying technologies were used.  相似文献
