为了解新疆马疱疹病毒1型（EHV-1）主要毒力基因遗传进化情况并构建TK基因缺失株，本研究以EHV-1 XJ2015株DNA为模板，对其主要毒力基因TK、gI和gE全长进行克隆、测序及生物信息学分析，并扩增TK基因左右重组臂TKL和TKR，构建质粒pUC-TKLR，将扩增后的增强绿色荧光蛋白（EGFP，含有CMV+polyA）插入pUC-TKLR质粒，构建TK基因缺失打靶质粒。TK、gI和gE基因同源性分析结果显示，XJ2015株与国外EHV-1分离株TK、gI和gE基因同源性均较高，分别为99.8%~100.0%、99.6%~100.0%和99.9%~100.0%；与EHV-3分离株同源性均最低，分别为72.9%、59.4%和62.1%；遗传进化分析显示，3个基因均与国外EHV-1同属于一个遗传进化分支，与EHV-9和EHV-4进化关系较近，但与EHV-3进化关系较远，表明XJ2015毒株与国外EHV-1毒株TK、gI、gE基因核苷酸上差异不明显，没有明显的地域性特征，功能基因保守且进化缓慢，同源基因功能相同或相近；经PCR扩增、酶切、测序及转染鉴定，本试验成功构建了用于TK基因缺失的打靶质粒pUC-TKLR-EGFP。通过对EHV-1主要毒力基因的分析及TK基因缺失打靶载体的构建，为新疆地区马鼻肺炎流行病学调查分析、TK基因缺失株的构建提供理论依据。  相似文献

Surgical repair of skull fractures in four horses using cuttable bone plates.     

B A Dowling  A J Dart  G Trope 《Australian veterinary journal》2001,79(5):324-327

Three horses with severely comminuted, open facial bone fractures and one horse with a comminuted, open orbital rim fracture were referred for treatment. Severe facial bone asymmetry and epistaxis were apparent in all cases and subcutaneous emphysema was present in two, however physical and neurological examinations were otherwise normal. Radiography and endoscopy were of some use in assessing the degree of damage, although the true extent of the damage was more apparent at surgery. Surgical reduction of the fractures was recommended to maximise cosmetic and functional outcome. After surgical debridement and reduction of the fractures the bone fragments remained unstable and were not amenable to stabilisation with interfragmentary wires alone, so 2 mm cuttable bone plates were used to maintain fracture alignment. Screw migration occurred in three horses and in one of these horses the plate had to be removed. Other complications were minor and in all horses the fractures healed with good cosmetic and functional outcome. The use of cuttable bone plates should be considered as a reasonable alternative to inter-fragmentary wiring for unstable, comminuted fractures of the facial bones, even where fractures are open.  相似文献

How to perform transvenous electrical cardioversion in horses with atrial fibrillation   总被引：1，自引：1，他引：1  

M. Kimberly J. McGurrin DVM  Dipl ACVIM  Peter W. Physick-Sheard BVSc  MSc  FRCVS  Daniel G. Kenney DVM  Dipl ACVIM 《Journal of Veterinary Cardiology》2005,7(2):109

Electrical cardioversion of atrial fibrillation is a well-established technique for restoration of sinus rhythm in humans. While transthoracic cardioversion is more commonly used, transvenous electrical cardioversion (TVEC) has been reported as having higher efficacy at substantially lower energy levels. In horses, treatment of atrial fibrillation has essentially been limited to the administration of quinidine salts either orally or intravenously. TVEC provides an alternative to quinidine salts, especially for those animals in which quinidine is neither effective nor tolerated. The present report details this technique in horses, discusses possible complications of the procedure, and provides guidance for successful outcome. Still and video images are used to illustrate details with regard to TVEC techniques in horses. Please view supplemental material for the videos.  相似文献

Characterization of Nitrate-Reducing and Amino Acid–Using Bacteria Prominent in Nitrotoxin-Enriched Equine Cecal Populations     

《Journal of Equine Veterinary Science》2016

Horses can be at risk for nitropoisoning by consuming plants containing 3-nitro-1-propionic acid or 3-nitro-1-propanol and to a lesser extent by plants containing nitrate. Populations of equine cecal microbes enriched for enhanced rates of 3-nitro-1-propionic acid (NPA) or nitrate metabolism were cultured for NPA- or nitrate-metabolizing bacteria on basal enrichment medium or tryptose soy agar supplemented with either 5-mM NPA or nitrate and under H₂:CO₂ (20:80) as the energy source. After 72 hours, separated colonies picked from plates, or roll tubes were cultured in fresh broth medium for 72 hours and then identified by 16S rRNA gene sequencing. Isolates from the NPA-enriched populations were identified as Streptococcus lutetiensis (five strains), Escherichia coli (two strains), and Sporanaerobacter acetigens (one strain). Strains isolated from nitrate-enriched populations were identified as Escherichia coli (one strain) and Wolinella succinogenes (three strains). None of these strains degraded NPA. Enriched populations of equine cecal microbes, the isolated pure strains and the type strain of Denitrobacterium detoxificans, a competent NPA-metabolizing microbe, were examined using denaturing gradient gel electrophoresis (DGGE). The DGGE analysis indicated that none of the strains in the enriched population of equine cecal microbes were similar to D. detoxificans. However, we report for the first time the isolation of the anaerobic amino acid–using Sporanaerobacter acetigenes from the equine cecum.  相似文献   

Seroprevalence and Risk Factors Associated With Corynebacterium pseudotuberculosis Detectable Antibodies in Equids in Alabama     

《Journal of Equine Veterinary Science》2017

A cross-sectional serological survey was carried out to screen the equine population of the nonendemic state of Alabama for the presence of detectable antibody titers against Corynebacterium pseudotuberculosis. A second objective was to determine the association of detectable titers with risk factors such as exposure to ruminants or previous travel to endemic states. A total of 342 equine serum samples from 40 Alabama counties were analyzed using the synergistic hemolysis inhibition test (SHI). The prevalence of detectable antibody titers (≥1:8) was 52.5% (95% confidence interval [CI], 47%–57.9%). Titers ≥1:128 were detected in 2.63% (95% CI, 1.2%–4.9%), and titers ≥1:512 were detected in 0.3% (95% CI, 0%–1.6%) of the sampled population. In the final generalized linear model, age (P < .001), breed (P = .023), and contact with cattle (P = .05) were associated with increasing SHI titers. Contact with goats was associated in the initial but not in the final analysis (P = .19). Previous travel was not associated with increasing SHI titer (P = .97). The results demonstrated a high prevalence of low detectable titers and low prevalence of titers ≥ 1:128 in a nonendemic population. Further evaluation of SHI cutoff titers and accuracy is warranted to reduce the risk of a false positive diagnosis.  相似文献
