绵羊痘病的诊治报告

绵羊痘是由痘病毒科的绵羊痘病毒引起的、危害极大的一种急性、热性、高度接触性传染病,其特征为：病羊的口腔、唇、乳房、尾部、四肢内侧等部位黏膜和皮肤以及被毛稀疏处发生特异性痘疹、痘块。绵羊痘是各种家畜痘病毒中危害最为严重的痘疹,可造成绵羊死亡、流产和死胎等。如早期发现,及时对症治疗,大部分成年绵羊可以耐过,死亡率也较低,但羔羊的死亡率可高达100%,造成严重的经济损失,所以对养羊业的危害特别大。

Passive protection of sheep against capripoxvirus

The close antigenic relationship between strains of capripox was shown by passively immunising sheep with serum against capripoxviruses isolated from a sheep and from a goat. Sheep immunised with immune serum to Oman sheep pox or Yemen goat pox resisted challenge with Yemen goat pox or Nigeria sheep pox respectively. Lambs born to sheep previously infected with isolates of capripox from the Sudan, India and Nigeria were also protected against challenge with Yemen goat pox.     

Sheep pox disease outbreaks in Madras Red and Mechery breeds of indigenous sheep in Tamilnadu, India

Sheep pox disease outbreaks were recorded among Madras Red (n=145) and Mechery (n=80) breeds of indigenous sheep on three farms in Tamilnadu. Over both breeds, adult mortality rate ranged from 2.66% to 37.5% and lamb mortality ranged from 10% to 17.33%. However, mortality was more in Mechery sheep (50% overall; 37.5% adults, 12.5% lambs) than in Madras Red sheep (24.28% overall; 10.34% adults, 13.79% lambs). The clinical signs observed were high fever, anorexia, respiratory distress, mucopurulent nasal discharge and in a few cases diarrhoea. Cutaneous lesions were mainly observed around nostrils, eyes, lips, ears and in the abdomen. Most of the lesions were covered with purulent materials and on cleaning with sterile swabs, fresh wounds were observed. Dry scabs were also observed over the oral commissure and maxillary areas, which on removal exposed fresh wounds. Important observations on necropsy were severe nodular lesions in the lungs and intestine. The disease was diagnosed as sheep pox by agar gel immunodiffusion test, isolation of virus and its neutralization in BHK(21) cells by specific antiserum and by electron microscopy.     

The current status of sheep pox disease

Sheep are the moving banks of shepherds and their economic contribution in terms of meat, wool and skin/hide is immense. Various infectious diseases jeopardize the optimum productivity; among which sheep pox is more important as the disease restricts the export of sheep and their products besides other economic losses. Although, clinical signs are indicative of the disease but a laboratory confirmation is necessary for unequivocal diagnosis and studying epidemiology. The causative agent, sheep pox virus (SPV), is antigenically and genetically closely related to goat pox virus (GPV) and lumpy skin disease virus (LSDV), the other members of the genus capripox virus. In some countries, SPV and GPV are cross infective to small ruminants posing problem in diagnosis and epidemiology. However, recent studies have showed that the viruses are phylogenetically distinct and can be differentiated by molecular tools. Prophylaxis using attenuated vaccines is the choice of control measure as the immunity is long lasting. Detailed information on isolation, identification, pathology, epidemiology, diagnosis and prophylaxis would not only help in updating the knowledge of scientific fraternity but will be useful to the policy makers in order to formulate appropriate measures for control and eradication of the disease. This synthesis is to present an up-to-date review of the disease and its control to provide the reader with an overview of the problem.     

羊痒病病原学特点与流行病学特征的研究进展

羊痒病是由羊痒病病毒在绵羊和山羊体内相互作用引起的一种中枢神经系统渐进性退化的疾病。该传染病的临床症状以潜伏期长、剧痒、中枢神经系统变性、共济失调和病死率高为主要特征。本病对养羊业危害较大,是最早所知的动物传染性海绵状脑病。羊痒病疫情虽然在中国发生较少,但目前在世界各地均有流行,对中国的潜在威胁也越来越大。因此,加强对该病的病原学、流行病学特征的认识对其综合防控具有十分重要的意义。作者主要介绍了目前国内外羊痒病病原学和流行病学特征的研究进展及综合性防控措施,以期为其防控提供一定的理论依据。     

羊痘的研究进展

羊痘病毒能引起山羊痘、绵羊痘和牛的结节性疹块病。羊痘是以发热、全身性的皮肤损伤、痘疹和淋巴结病变为特征。羊痘病毒是所有动物痘病毒中最为重要的一种，严重影响养羊业和国际贸易的发展。本文从病原学、流行病学、诊断和预防控制等方面对羊痘做一综述。虽然此病从临床症状和宿主特异性上很容易做出诊断，但进一步的实验室确诊还是必要的，现已有多种检测方法和诊断试剂。控制该病最有效的方法还是使用疫苗对易感动物进行免疫接种。

Understanding the epidemiology of sheep-pox outbreaks among vaccinated Algerian sheep and post vaccination evaluation of the antibodies kinetics of the commercially used vaccine

Sheep pox is a disease of veterinary concern to small ruminant producers and veterinary diagnosticians, because of the associated tangible economic losses. The epidemiological analysis of sheep pox, among vaccinated sheep flock in Algeria from 2007 to 2016, showed that the disease outbreaks occurred every year and across all Algeria region with an average of 44.9 outbreaks per year, these outbreaks correlate with the region climate, the flocks’ density and the transhumance practices. The one-year post vaccination antibody kinetics evaluation study of the commercially used vaccine in Algeria demonstrated a mild humoral response, the neutralization index range between 0.73 and 1.22. Therefore, the present study recommends a challenge study, using a virulent local strain, to evaluate the vaccine efficacy. Furthermore, quality control approach for the vaccine production processes is required.
