影响农村动物疫病防控工作的因素及对策 总被引：1，自引：1，他引：0
<正>近年来,口蹄疫、高致病性禽流感、高致病性蓝耳病等一些重大动物疫病呈高发态势。为了保障养殖业持续稳定发展和人体健康,维护公共卫生,动物疫病防控工作倍受各级政府重视,相关法律法规不断完善,防控措施不断加强,防控投入逐年加大,防控体系日渐完善,防控效果亦明显好转。但由于受诸多因素的影响,农村动物疫病防控工作在全国动物疫病防控体系中仍是最薄弱的一环,还存在着引发动物疫病发生和流行的隐患。根据当前农村动物疫病防控工作的实际,结合自己的工作实践就此谈一些看法,供商榷。 相似文献

近几年,市场上牛羊肉及其制品的需求量大幅增加,在一定程度上促进了牛羊养殖行业的发展,牛羊养殖的规模呈现出逐年扩大的趋势。值得注意的是,现阶段我国牛羊养殖过程中部分养殖人员对疫病防控工作的重视程度不够,对疫病防控技术的了解较少,疫病防控工作开展情况并不理想,对牛羊养殖业的发展造成了一些负面的影响。本文对牛羊动物疫病防控措施及技术进行了详细的阐述,以期能为养殖人员提供一些帮助。 相似文献

A virus from fish with lymphocystis disease was isolated in fish cell cultures. Eleven serial transfers were made and the pathognomonic lymphocystis cells were produced in vitro in each transfer. Fish inoculated with 6th- and 9th-passage material developed the disease, and virus was reisolated front them. 相似文献

A formalin-inactivated whole SIV vaccine confers protection in macaques 总被引：48，自引：0，他引：48

A vaccine against human immunodeficiency virus (HIV) would be highly effective in stopping the acquired immunodeficiency syndrome (AIDS) epidemic. A comprehensive evaluation of potential vaccine methodologies can be made by means of the simian model for AIDS, which takes advantage of the similarities in viral composition and disease potential between simian immunodeficiency virus (SIV) infection of rhesus macaques and HIV infection in humans. Immunization with a formalin-inactivated whole SIV vaccine potentiated with either alum and the Syntex adjuvant threonyl muramyl dipeptide (MDP) or MDP alone resulted in the protection of eight of nine rhesus monkeys challenged with ten animal-infectious doses of pathogenic virus. These results demonstrate that a whole virus vaccine is highly effective in inducing immune responses that can protect against lentivirus infection and AIDS-like disease. 相似文献

Chemokine receptors serve as portals of entry for certain intracellular pathogens, most notably human immunodeficiency virus (HIV). Myxoma virus is a member of the poxvirus family that induces a lethal systemic disease in rabbits, but no poxvirus receptor has ever been defined. Rodent fibroblasts (3T3) that cannot be infected with myxoma virus could be made fully permissive for myxoma virus infection by expression of any one of several human chemokine receptors, including CCR1, CCR5, and CXCR4. Conversely, infection of 3T3-CCR5 cells can be inhibited by RANTES, anti-CCR5 polyclonal antibody, or herbimycin A but not by monoclonal antibodies that block HIV-1 infection or by pertussis toxin. These findings suggest that poxviruses, like HIV, are able to use chemokine receptors to infect specific cell subtypes, notably migratory leukocytes, but that their mechanisms of receptor interactions are distinct. 相似文献

In China, a soil-borne virus causing a disease of winter wheat and associated with Polymyxa graminis, has been reported for many years and is now recognized as a new species, Chinese wheat mosaic virus (CWMV). Since the determination of its genomic sequence, more progress has been made in understanding its genomic structure and functions. Molecular and serological methods have been developed to help survey the distribution of the virus and to provide the basic information needed for disease forecasting and control. At present, the best countermeasure is cultivation of resistant wheat varieties. In addition, development and application of some auxiliary countermeasures, such as rotation of non-host crops, delayed seed-sowing, reasonable application of nitrogen fertilizer, and treatment of imported seeds with fungicides before sowing, may be helpful for controlling the disease. The viral distribution and damage, virion properties, genome organization and spontaneous mutation, temperature sensitivity, and disease management options are here reviewed and/or discussed to help in developing more cost-effective countermeasures to control the disease in the future. 相似文献

植物遭受病毒侵染后,常表现出花叶、发育畸形、褪绿、坏死等症状。在农业生产中,这些症状的发生直接导致作物的产量/品质下降,有些造成严重的经济损失。因而,病毒病症状发生的分子机制长期以来一直为人们所关注。本文结合近年来国内外最新的研究报道,分别从病毒和寄主两个方面,总结归纳了介导症状发生的病毒元件以及参与症状发生的寄主因子,并在此基础上分析讨论了病毒病症状发生的分子机制。 相似文献
