水貂阿留申病的研究进展

水貂阿留申病(Aleutian disease of mink,ADM)是由水貂阿留申病细小病毒(Aleutian mink disease parvovirus,AD-MV)引起的一种慢性、进行性传染病,一直是危害世界养貂业健康发展最重要的疫病之一。到目前为止,还没有疫苗可成功用于ADM的预防,也没有特异有效的治疗方法,唯一可行的防治方法就是通过多次特异性检疫,淘汰病貂,净化貂群。笔者对阿留申病的病原学、发病机制、防治措施等方面进行概述,为临床防治水貂阿留申病提供了理论基础。     

猪咬尾症的发病原因分析

猪咬尾症在现代规模化养猪场常发的一种疾病,特别是在猪场饲养密度较大,饲养管理较差的情况下,发生猪咬尾症较多。如果对这种不良行为及时加以制止,则会发生猪的尾巴溃烂和化脓,严重者则死亡,继而对猪只的生长发育以及猪场的经济效益带来较大的影响。找出诱发猪咬尾症的真正原因是防治该病发生的关键所在。本文就猪咬尾症主要的发病原因进行了分析,为控制该病的发生提高依据。

COMPARISON OF UPPER GASTROINTESTINAL RADIOGRAPHIC FINDINGS TO HISTOPATHOLOGIC OBSERVATIONS: A RETROSPECTIVE STUDY OF 41 DOGS AND CATS WITH SUSPECTED SMALL BOWEL INFILTRATIVE DISEASE (1985 to 1990)

It was the intent of this study to define which, if any, radiographic observations corresponded with specific causes of diffuse infiltrative small bowel disease and if radiographic findings could differentiate inflammatory disease from neoplastic disease and either of them from normal. Bowel spasticity, luminal narrowing, and thumbprinting tend to indicate the presence of tumor more often than inflammatory disease. Increased bowel gas in cats and barium adhesion in dogs and cats suggest that a component of enteritis is present. Decreased bowel gas in dogs is more often associated with obstructive disease, but is not helpful in differentiating diffuse inflammatory disease from diffuse neoplastic disease. While several observations that can foster differentiation of neoplastic from inflammatory disease were found, this study also indicated that the UGI lacks a high degree of predictive value other than to indicate the presence of infiltrative small bowel disease.

裂谷热(RVF)是由蚊传播的急性、以高热为特征的病毒性传染病,主要感染牛、羊等哺乳动物,也可感染人,被OIE列为A类疫病.虽然我国目前尚未发生RVF的报道,但近年来该病的分布范围有不断扩大的趋势.随着经济全球化的发展,RVF对我国的畜牧业以及人类的健康构成威胁.在国内没有报告RVF病例的情况下,国内对RVF的认识普遍不足,因此需要国境口岸加强对裂谷热进行检测和监测,防止RVF传入是必需的,为加强对裂谷热检测技术的认识,现对裂谷热诊断技术的研究进展进行综述.     

Emergency Presentations of Exotic Mammal Herbivores

Companion exotic mammal herbivores may be diagnosed with chronic disease that the owner believes is causing acute clinical illness. It is generally believed that because of the enhanced disease-masking ability of these “prey” species, numerous disease states may go unnoticed for a significant period. A veterinarian should be knowledgeable about this behavior trait and consider its possible effects when assessing the patient's health status. In some cases, the chronic disease condition may respond rapidly to treatment, whereas with other diagnoses, treatment is more frustrating. This article describes a selection of chronic disease conditions that one may diagnose in guinea pigs (e.g., hypovitaminosis C, trixacariasis, urolithiasis, dental disease), chinchillas (e.g., dental disease), and rabbits (e.g., dental disease, renal failure, cranial thoracic mass disease). Gastrointestinal and cardiovascular disease problems diagnosed in companion exotic mammal herbivores are covered elsewhere in this journal issue.     

边界病的研究进展

边界病（border disease,BD）是由边界病病毒（border disease virus,BDV）引起绵羊和山羊感染的一种传染性疾病,在世界范围内给畜牧业生产造成巨大的经济损失。该病临床表现为母羊生殖障碍,羔羊畸形、震颤、多毛等。BDV在绵羊、牛和猪的种间传播经常发生,给该病的诊断带来困难。目前,尚无有效的疫苗用于边界病的防控,因此,了解不同区域的边界病流行情况有助于防止其传播并优化控制措施。结合国内外近期研究报道,从病原学、流行病学、诊断措施等方面对边界病进行综述,以期为该病的防控工作提供参考。     

电针配合药物治疗犬椎间盘突出

近年来,犬椎间盘突出症在宠物临床上越发的常见。由于本病的发病原因较为复杂、发病过程多为慢性,在诊断时难于判断,同时在治疗时以手术疗法为主治愈率较低。临床实践表明应用电针配合药物对该病进行治疗,治愈率大大提高。作者对犬椎间盘突出的病因与诊断进行了阐述,并说明了电针复合药物对该病的治疗机理,为该病的诊断提供系统的理论指导,为电针配合药物治疗方案的推广打下坚实的基础。     

Immunity to filarial nematodes

Mosquito-borne filarial nematodes cause the severe, debilitating disease of human lymphatic filariasis. In areas endemic for this disease, differential responses range from putative immunity through asymptomatic microfilaraemic infection to chronic pathology. Current research in mouse models of infection is elucidating the immunological mechanisms that can lead to immunity against this disease. In this review, the importance of different immunological pathways are discussed in relation to their role in human disease and in terms of their ability to kill separate developmental stages of the filarial parasite.

犬牙周病的临床研究进展

牙周病(periodontal disease, PD)是由细菌在牙齿表面聚集形成的牙菌斑和牙结石逐渐侵蚀牙周组织,引发周围组织炎症的一类疾病。根据疾病的发展进程,可分为齿龈炎与牙周炎2个阶段。在小动物临床疾病中牙周病尤为常见,世界范围内约有80%的成年犬患有该病。由于饲主对于犬的口腔保健意识薄弱且该疾病隐秘性较高,患犬就诊时往往已出现牙周支持组织不可逆的损伤,细菌及其毒力因子通过血液循环进入全身从而引发系统性疾病的风险大大提高。但目前犬牙周病的核心致病菌属、菌群失调的原因与发病机制尚不明确。因此,笔者基于高通量测序方法的病原学研究结果,分析与疾病发展相关的微生物群。同时,整合目前世界通用的最新犬牙周病临床诊断分级标准及犬牙周病的中西医防治方案,分析犬牙周病与全身系统性疾病之间的相关性,系统综述犬牙周病在国内外小动物临床领域的研究进展,以期为该类疾病的临床诊疗提供理论参考,推进兽医师在临床实践中更高效地开展该类疾病的诊疗工作,并为犬牙周病相关的临床研究提供思路。

Pneumonia of pigs: a review

Pneumonia of pigs is one of the more important disease factors limiting pig production. Of the varieties of pneumonia affecting this species enzootic pneumonia caused by Mycoplasma spp. is the most common and most important. The major effects of this disease are lowered food conversion ratio and poor weight gain. Deaths are usually the result of secondary infection by necrotising, pus-forming bacteria. Eradication of the disease is expensive and requires depopulation and restocking. Control and treatment by antimicrobial agents is most effective if the drug combination used takes regard of the bacteria complicating the disease on any particular property. Other forms of pneumonia such as those caused by Haemophilus pleuropneumoniae, Salmonella cholerae-suis and Aujeszky's disease virus can be important on individual farms. The role of other agents such as Bordetella bronchiseptica and adenoviruses in respiratory disease of pigs remain to be clarified.     

Recent research on bovine paratuberculosis in South Korea

Bovine paratuberculosis (Johne's disease), a chronic and debilitating disease of ruminants caused by Mycobacterium avium subspecies paratuberculosis (MAP), is a major cause of chronic ruminant enteritis. A national eradication program has been in place in South Korea since the first report of the disease in 1967; however, only limited data on bovine paratuberculosis in South Korea are available. Some research, such as investigations of the reactivity of animal sera against MAP antigens, has been done in localized areas and in limited animal species. Compared with the worldwide situation, the development of diagnostic methods in South Korea has shown similar results even though some data were obtained from international collaborative studies. MAP is considered by some to be zoonotic, noting an association with Crohn's disease, although this issue is still controversial; however, research into this association is limited. Decisions based on disease priorities have hampered active progress in research on the disease. In this paper, we reviewed the available results generated from South Korea compared with global research. Finally, we propose a theme for future research.
