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.
绵羊是牧民移动的资源库,它们在肉类、羊毛和皮革方面的经济贡献巨大。各种传染病危及最佳生产力;其中绵羊痘更为重要,因为除了其他经济损失外,这种疾病还限制了绵羊及其产品的出口。虽然临床症状可指示该病,但明确诊断和研究流行病学仍需实验室确诊。病原体绵羊痘病毒(SPV)在抗原性和基因上与山羊痘病毒(GPV)和结节性皮肤病病毒(LSDV)密切相关,它们都是山羊痘病毒属的其他成员。在一些国家,SPV和GPV可交叉感染小型反刍动物,给诊断和流行病学带来问题。然而,最近的研究表明,这些病毒在系统发育上是不同的,可以通过分子工具进行区分。使用减毒疫苗进行预防是控制措施的选择,因为免疫力持久。关于分离、鉴定、病理学、流行病学、诊断和预防的详细信息不仅有助于更新科学界的知识,而且对政策制定者制定控制和根除该疾病的适当措施也将有用。本综述旨在对该病及其控制进行最新回顾,为读者提供该问题的概述。
