唾液可用于猪疾病诊断的样本

目前,猪的疾病防治仍然是养猪生产者迫切关心的问题,如何才能有效的防治猪疾病,保证猪的产量和收益?这就要对猪疾病的诊断有一定的了解,通常情况下,采用血液样本来检测猪疾病的状况,近年来,研究人员发现猪唾液样本同样能够诊断猪疾病,并且还有自身独特的优势,但这种技术还没有广泛推广,本文主要陈述了唾液样本用于猪疾病诊断的重要意义,同时还对猪唾液样本的发展现状进行了分析,此外,还论述了猪唾液样本检测疾病的发展前景,希望对猪疾病的诊断提供参考价值.     

当前猪病诊断方法存在的问题及解决途径

对疾病诊断是认识疾病的首要步骤，明确了病因才能为防控措施提供依据。多年来我国对猪病防控的收效难以达预期目的，虽原因众多，但其中关键原因之一是诊断不清，找不到真正病因，所以猪病就难以得到有效的控制，也就是这种诊断不明的状况，致使养猪生产者对猪病的防制无可适从。     

猪血液的实验室检测及数据分析技术

在现代养猪生产中,人们已经越来越不依赖于眼观和仅仅凭借经验来判断猪病了。那种认为"皮肤有出血点就是猪瘟","肝脏有坏死白点就是伪狂犬病","出现间质性肺炎就是弓形虫","出现腹泻不是PED就是TGE"等等观点早已被行业所抛弃。血液学的检测技术在当前的养猪生产中已经显得越来越重要。为指导养猪     

猪群监测新方法——唾液检测法

对猪群用唾液检测法来进行监测，这在国内正式报告尚属首次，但在美国已经在2年前用于检测PRRS病毒，而在人医上，唾液已经应用到检测艾滋病。人们习惯的血清学检测由于对血液采集技术要求高，对猪应激大，一些猪场往往只在发病时才对猪群进行检测，但如果唾液检测法能适用，     

今年上半年规模化养猪场猪病的特点

养猪生产中，由于亚临床感染、非典型感染及混合感染的存在，许多猪病若单凭临床症状分析则很难确诊。采用实验室检测、诊断技术对猪病的确诊就显得尤为重要。适时的、准确的诊断是猪病预防和控制的关键。通过实验室检测、诊断，一方面可以确定病原和猪体之间的关系，明确猪体（群）疫病存在状况，进而达到疫情监测的目的。     

浅谈中兽医的疾病诊断与防治方法

中兽医是祖国医学的重要组成部分,是我国劳动人民防治家畜疾病的经验与总结,中兽医对家畜疾病的诊断与防治具有独特的理论体系和丰富的经验。现将中兽医对疾病的诊断与防治方法简述如下,供参考。1诊断方法中兽医对疾病的诊断,临床上常用望、切、闻、问、触五种方法。1.1望诊就是观察病畜的神、色、形态及分泌物、排泄物的变化,主要包括观形（观外形）、察色（察口色）两部分。＂欲知内五行,先观外五行＂（内五行指     

猪胃肠炎的诊断与防治

胃肠炎是猪的一种常见、多发病,对养猪生产危害极大,可给养猪生产效益造成严重的经济损失。笔者于2000年以来,诊治本病共有千例有余,现将本病诊治技术及其体会报告如下：     

动物疾病诊断中问诊法的应用

随着近代科学的进展，应用于临床实际的各种检查方法十分复杂，特别是实验室的检查法、x射线诊断法、机能试验法以及心电描记、超声探查、放射性同位素的应用等方面的新技术在医学临床的普遍应用，使现代诊断技术有了很大的提高。     

猪血液的实验室检测及数据分析技术

血液学的检测技术在当前的养猪生产中已经显得越来越重要。为指导养猪生产提供更加科学的依据,为疫苗接种提供更加准确的评价标准,为饲养管理方式的采用和变更提供更加详实的数据,实验室检测结果的判定和数据分析技术越来越受到广大科技工作者和养猪生产者的关注,本文拟对此进行简述,以期抛砖引玉。     

Examination of body fluids

In dogs, the pericardial sac contains about 0.3 ml, and the pleural and peritoneal cavities 0-15 ml of clear, straw-colored fluid of pH 7.4, specific gravity 1.016, protein content less than 3.0 g/dl and cell count less than 3000/microliter. Fat can be cleared from chylous fluid with NaOH and ether. Inflammation is indicated by a cell count greater than 3000/microliter. Amylase levels in peritoneal fluid are elevated in necrotizing pancreatitis. The percentage of polymorphonuclear WBC exceeds 50% in bacterial inflammations. Normal joints contain less than 1 ml highly viscid, clear or straw-colored synovial fluid with less than 1000 nucleated cells/microliter. Synovial fluid becomes flocculent and less viscid in septic and occasionally in immune-mediated arthritis, often with cell counts greater than 75,000/microliter, with 75-90% polymorphonuclear WBC. Cerebrospinal fluid is normally acellular, clear and colorless but may be red, yellow or brown with intracranial hematomas. Viral or aseptic meningitis is characterized by mononuclear cell counts of less than 500/microliter. In acute bacterial meningitis, nucleated cell counts are greater than 1000/microliter, with most being polymorphonuclear WBC. Gram staining of cerebrospinal fluid is not useful.     

Oral pathology

Oral disease is exceedingly common in small animal patients. In addition, there is a very wide variety of pathologies that are encountered within the oral cavity. These conditions often cause significant pain and/or localized and systemic infection; however, the majority of these conditions have little to no obvious clinical signs. Therefore, diagnosis is not typically made until late in the disease course. Knowledge of these diseases will better equip the practitioner to effectively treat them. This article covers the more common forms of oral pathology in the dog and cat, excluding periodontal disease, which is covered in its own chapter. The various pathologies are presented in graphic form, and the etiology, clinical signs, recommended diagnostic tests, and treatment options are discussed. Pathologies that are covered include: persistent deciduous teeth, fractured teeth, intrinsically stained teeth, feline tooth resorption, caries, oral neoplasia, eosinophilic granuloma complex, lymphoplasmacytic gingivostomatitis, enamel hypoplasia, and "missing" teeth.
