Equine herpesvirus-1 is a highly prevalent and frequently pathogenic infection of equids. The most serious clinical consequences of infection are abortion and equine herpesvirus myeloencephalopathy (EHM). In recent years, there has been an apparent increase in the incidence of EHM in North America, with serious consequences for horses and the horse industry. This consensus statement draws together current knowledge in the areas of pathogenesis, strain variation, epidemiology, diagnostic testing, vaccination, outbreak prevention and control, and treatment. 相似文献

Objective – To describe a case of Dieffenbachia ingestion in a dog presented for dysphagia and airway obstruction successfully treated with a temporary tracheostomy and supportive care beyond that reported in the veterinary literature. Case Summary – An 8‐year‐old male neutered Labrador Retriever, weighing 30 kg, was presented with the complaint of choking and gagging. Abdominal radiographs showed that he had a distended stomach full of foreign material and a gastrotomy was performed. After receiving preanesthetic medication, the dog developed inspiratory stridor and during anesthetic induction, marked oropharyngeal swelling complicated tracheal intubation. During surgery a large amount of dog bedding and Dieffenbachia plant material was removed. Because of the severity of the oropharyngeal swelling, the dog required a temporary tracheostomy and treatment for an acute allergic reaction related to the Dieffenbachia ingestion. The patient was discharged after 6 days in the hospital and had no significant complications. New or Unique Information Provided – To our knowledge, this is the first reported case of successful treatment of an airway obstruction related to the toxicity of Dieffenbachia ingestion. 相似文献

Under experimental challenges, the gastrointestinal (GI) tract of fish has been proposed as an infectious route of several pathogenic bacteria. Is this also the case for diseased fishponds? A field research was conducted to verify this hypothesis. A crucian carp (Carassius carassius) reared fishpond with motile Aeromonas septicaemia outbreak was sampled in this study. A total of 62 strains of Aeromonas hydrophila were isolated and identified. The clonal relationship among these strains was determined by sequencing the gyrB gene, ERIC‐PCR, RAPD‐PCR, and the presence of seven virulence genes. Strains with identical genotypes were further confirmed as the same clone by multilocus sequence typing analysis. Experimental infection assays were also conducted in zebrafish (Danio rerio). The results show that the same clone strains identical to those in the blood of diseased fish existed in the intestinal digesta of diseased and uninfected fish. Regardless of their origins, all these strains were highly pathogenic to zebrafish. The result indicates that pathogenic strains of A. hydrophila had existed in the GI tract of fish before the infection occurred. This increases our knowledge on infectious route of A. hydrophila in crucian carp. 相似文献

The aim of the present study was to evaluate the effects of three formulated diets: wheat‐gluten‐protein‐based diets supplemented with Lys‐Gly dipeptide (LG) or free lysine and glycine (FL), a control diet without lysine supplementation (C) and commercial starter Bio Oregon (BO) for on the growth and digestive system morphology of yellow perch. After 48 days of experimental feeding, fish fed LG diet showed the highest body mass. Fish fed LG diet showed the highest number of gastrin/cholecystokinin positive cells and the lowest number of CD3‐positive cells. The brush border of anterior intestine was the most PepT1 immunopositive in fish fed LG diet, the weakest in fish fed C diet. The largest hepatocytes were observed in fish fed BO, while the smallest in those fed FL diet, the difference being statistically significant. Relative hepatocyte cytoplasm volume occupied by lipids was higher in fish fed BO and FL compared to those fed C and LG. Number of proliferating cell nuclear antigen‐positive hepatocyte nuclei did not significantly differ among experimental groups. These results indicate that wheat‐gluten‐protein‐based diets supplemented with dipeptide Lys‐Gly (LG) were appropriate for yellow perch. 相似文献

将海洋红酵母(Rhodotorula sp.) C11以104、105和106 CFU/g饵料添加到基础饵料中,每一剂量组设3个平行,每一平行50头幼参,用100 L塑料桶进行30 d静水充气养殖试验。试验期间每日投饵1次,投喂量为幼参体重的5%。投喂试验结束后,评估其对幼参消化酶及免疫反应的影响。结果显示,与对照组比较,投喂海洋红酵母C11 104、105 CFU/g,显著提高了幼参肠道胰蛋白酶活力(P<0.05);投喂海洋红酵母C11 104 CFU/g,显著增加淀粉酶活力(P<0.05)。投喂海洋红酵母C11 105 CFU/g,幼参体腔细胞的吞噬活力显著高于对照组(P<0.05)。与投喂基础饵料的幼参比较,投喂海洋红酵母C11 105、106 CFU/g,幼参具有较高的体腔液溶菌酶(LSZ)活力(P<0.05)。投喂海洋红酵母C11 104 CFU/g,幼参具有较高的体腔细胞裂解液(CLS)LSZ活力(P<0.05)。投喂海洋红酵母C11 104 CFU/g,幼参体腔液总一氧化氮合酶(T-NOS)活力显著增加(P<0.05),投喂海洋红酵母C11 104、105、106 CFU/g,幼参CLS的T-NOS活力显著提高(P<0.05)。本研究表明,饵料补充海洋红酵母C11可促进幼参的消化酶活力和免疫反应。 相似文献

为探究福寿螺(Pomacea canaliculate)能否有效利用草鱼(Ctenopharyngodon idellus)摄食水葫芦(Eichhornia crassipes)后产生的粪便,该研究对草鱼粪便、水葫芦饵料处理组福寿螺的生长、体组成、消化酶活力、氮磷富集量等进行比较分析。结果显示:1)两组福寿螺体质量均极显著增加(P<0.01),其中水葫芦组特定生长率(SGR)、食物转化率(FCR)均极显著高于草鱼粪便组(P<0.01);成活率(SR)无显著差异(P>0.05);2)两组福寿螺软体部的体组成差异不显著(P>0.05);3)水葫芦组的胃淀粉酶活力显著高于草鱼粪便组(P<0.05),纤维素酶、脂肪酶活力无显著差异(P>0.05);4)两组福寿螺均能有效富集氮(N)、磷(P)元素,且两组间无显著差异(P>0.05)。结果表明福寿螺摄食草鱼粪便不仅能满足螺本身的基本生长需求,还能间接减轻水体中的N、P负荷,表明在已有的“水体-水葫芦-草鱼”养殖模式中,可利用福寿螺解决草鱼粪便污染问题。 相似文献
