自2019年非洲猪瘟在我国首次出现以来,该疫病给我国养猪业造成了毁灭性的打击,造成国内生猪存栏急剧减少,猪肉产量降低,国内猪肉价格升高,对我国生猪养殖业和猪肉食品安全造成了严重的威胁。非洲猪瘟疫情是由非洲猪瘟病毒感染引起猪只大量死亡的一类烈性传染病,因此了解非洲猪瘟的流行病学特点和非洲猪瘟病毒的特征,在非洲猪瘟疫情防控方面十分重要。本文对非洲猪瘟病毒的病毒学特点和非洲猪瘟的流行病学特点等进行综述,为非洲猪瘟疫情的防控、相关抗非洲猪瘟病毒的药物和疫苗的研发提供参考。 相似文献

为了科学防控非洲猪瘟,国务院、农业农村部等先后出台多套防控非洲猪瘟的文件和措施,对科学防控非洲猪瘟起到了关键作用。虽然非洲猪瘟不传染人,但一旦在我国流行开来,将对我国养猪业带来不可估量的影响和损失。当前非洲猪瘟尚无有效的疫苗,发现非洲猪瘟只能通过封锁、扑杀、无害化处理等手段进行点状拔出。本文对非洲猪瘟的特点及其关键防控措施进行综述。 相似文献

非洲猪瘟（ASF）是由非洲猪瘟病毒（ASFV）引起的一种的热性、斑疹性、高度接触性的猪传染病。世界首例ASF于1909年在非洲肯尼亚被发现。由于其传染性强,且发病后致死率高,给生猪养殖带来极大的危害,且严重影响了畜牧经济的发展。特别是在全球禁抗背景下,提高猪只免疫力成为防控ASF的重要环节。文章就ASF特征、临床表现,就如何在禁抗下提高猪免疫力提出一些建议。 相似文献

非洲猪瘟是养猪业的第一杀手,自1921年东非国家肯尼亚首先出现非洲猪瘟疫情以来,这个病毒已经在非洲亚洲欧洲等区域传播了近百年,对世界养猪业造成了无可估量的损失。我国于2018年8月在辽宁省沈阳市首次发生非洲猪瘟疫情,并在极短的时间内传遍全国,对我国养猪行业的发展产生了巨大的影响,养猪业在近2年时间里发生了极大的变化。文章采用TaqMan探针实时荧光PCR技术,阐述一种快速、准确的非洲猪瘟病毒检测方法,并结合非洲猪瘟传播感染途径的特点,制定科学的诊断程序与防控措施来保证养猪业的生产安全。 相似文献

The known distribution of African swine fever (ASF) virus in Africa is reviewed in relation to the distributions of its free-living hosts as are the infection rates of these species in different localities in southern Africa. Mechanisms by which ASF virus is maintained in its sylvatic state and ways in which the infection may enter domestic pig populations are discussed. 相似文献

African swine fever (ASF) is one of the most complex infectious swine diseases and the greatest concern to the pig industry owing to its high mortality and no effective vaccines available to prevent the disease. Since the first outbreak of ASF in pig farms, ASF has been identified in 14 pig farms in four cities/counties in South Korea. The outbreak was resolved in a short period because of the immediate control measures and cooperative efforts. This paper reviews the ASF outbreak and the experience of successfully stopping ASF in pig farms in South Korea through active responses to prevent the spread of ASF. In addition, suitable changes to build a sustainable pig production system and collaborative efforts to overcome the dangerous animal disease, such as ASF, are discussed. 相似文献

We explored observed risk factors and drivers of infection possibly associated with African swine fever (ASF) epidemiology in Uganda. Representative sub-populations of pig farms and statistics were used in a case-control model. Indiscriminate disposal of pig viscera and waste materials after slaughter, including on open refuse dumps, farm-gate buyers collecting pigs and pig products from within a farm, and retention of survivor pigs were plausible risk factors. Wire mesh-protected windows in pig houses were found to be protective against ASF infection. Sighting engorged ticks on pigs, the presence of a lock for each pig pen and/or a gate at the farm entrance were significantly associated with infection/non-infection; possible explanations were offered. Strict adherence to planned within-farm and community-based biosecurity, and avoidance of identified risk factors is recommended to reduce infection. Training for small-scale and emerging farmers should involve multidimensional and multidisciplinary approaches to reduce human-related risky behaviours driving infection. 相似文献

非洲猪瘟疫情的暴发对我国生猪产业,尤其是生猪产业链价格产生巨大影响。为研究非洲猪瘟背景下河北省生猪产业链价格波动及传导机制,文章选取河北省2018年8月至2020年6月周度平均仔猪价格、生猪价格和猪肉价格作为生猪产业链价格代表,通过构建协整和误差修正模型、格兰杰因果检验方法分析非洲猪瘟对生猪产业链内部价格传导过程的影响。研究结果表明：非洲猪瘟背景下河北省生猪产业链价格存在长期均衡关系,但其上下游价格传导受阻,而屠宰场和销售市场的垂直整合度增强;生猪产业链中存在一定的反向误差修正机制;生猪产业链上、中游对下游价格的影响更为明显,并据此提出非洲猪瘟背景下河北省调控生猪产业链价格的政策建议。 相似文献

Fourteen African swine fever (ASF) outbreaks occurred in the pig farms in the northwestern region of South Korea, near the border with North Korea, from September 16, 2019 to October 9, 2019. Active and passive surveillance on the ASF-infected farms indicated that the infection was limited only to pigsties where the infected pigs were detected on the farm for the first time before further transmission to other pigsties and farms. This early detection could be one of the pivotal factors for the prompt eradication of ASF in domestic pig farms within 1 month in the northwestern region of South Korea. 相似文献
