Necrotizing Meningoencephalitis in Atypical Dog Breeds: A Case Series and Literature Review

Background

Canine necrotizing meningoencephalitis (NME) is a fatal, noninfectious inflammatory disease of unknown etiology. NME has been reported only in a small number of dog breeds, which has led to the presumption that it is a breed‐restricted disorder.

Hypothesis/Objectives

Our objective was to describe histopathologically confirmed NME in dog breeds in which the condition has not been reported previously and to provide preliminary evidence that NME affects a wider spectrum of dog breeds than previously reported.

Animals

Four dogs with NME.

Methods

Archives from 3 institutions and from 1 author''s (BS) collection were reviewed to identify histopathologically confirmed cases of NME in breeds in which the disease has not been reported previously. Age, sex, breed, survival from onset of clinical signs, and histopathologic findings were evaluated.

Results

Necrotizing meningoencephalitis was identified in 4 small dog breeds (Papillon, Shih Tzu, Coton de Tulear, and Brussels Griffon). Median age at clinical evaluation was 2.5 years. Histopathologic abnormalities included 2 or more of the following: lymphoplasmacytic or histiocytic meningoencephalitis or encephalitis, moderate‐to‐severe cerebrocortical necrosis, variable involvement of other anatomic locations within the brain (cerebellum, brainstem), and absence of detectable infectious agents.

Conclusions and Clinical Importance

Until now, NME has only been described in 5 small dog breeds. We document an additional 4 small breeds previously not shown to develop NME. Our cases further illustrate that NME is not a breed‐restricted disorder and should be considered in the differential diagnosis for dogs with signalment and clinical signs consistent with inflammatory brain disease.

膨化浮性鱼饲料的特点及应用

随着水产养殖业向规模化、集约化、专业化的方向发展,对水产饲料的要求也越来越高,传统的粉状配合饲料和颗粒配合饲料存在着水中稳定性差,沉降速度快,易造成饲料散失浪费和水质污染等弊端,已越来越不适应现代水产养殖的需要,而浮性饲料能较好地克服粉状和颗粒饲料的...     

不同猪群营养系列化配方研究试验（小试）

本试验采用单因子三处理试验设计,分别选择HB920、YX和YW三种预混料对湖北白猪进行对比饲养试验.全程共分四个阶段,第一阶段从0~45日龄断奶,第二阶段从45~75日龄,第三阶段从75~120日龄,第四阶段从120日龄至结束.试验结果表明,三种料型对平均日增重、料肉比和瘦肉率三项指标作用差异均不显著.
