高致病性禽流感是一种人兽共患的烈性传染病,在禽类感染此种疫病后发病急、传播快、发病率和病死率都很高。高致病性禽流感除直接影响养禽业的发展,还影响禽类产品的安全和影响国际、国内贸易,另外还会引起严重的公共卫生问题。文章就高致病性禽流感的流行特征及应对措施进行阐述,以便更好的防控高致病性禽流感的发生。 相似文献

禽流感是指由于禽流感病毒导致人与动物共患的一种急性传染病,主要发生在鸡、鸭等禽类中,严重时临床症状表现为全身败血症等。根据禽流感病原体的不同,可分为非致病性、低致病性和高致病性3种类型,其中高致病禽流感发病急、传播速度快、死亡率高,被世界卫生组织列为A类动物疫病。该文通过对高致病禽流感抗体检测过程中存在的问题进行探讨和分析,提出了有利于改善抗体检测的措施,为有效防控高致病禽流感提供参考。 相似文献

继10月18日欧盟25国外长在卢森堡召开紧急会议讨论应对禽流感措施后,联合国相关组织负责人杜曼奇目前担心候鸟会将疫情带到中东及非洲东部、北部,国外高致病性禽流感疫情呈明显扩散蔓延态势,全球严阵以待,拉响警报。我国农业部于9月29日召开了首次全国高致病性禽流感防控工作视频会议,国务院副总理回良玉10月20日主持召开了国务院防控高致病性禽流感工作会议,拉响了全国防控禽流感的警报。作为肉鸡从业者,去年的1月27日的禽流感疫情通报及政府相关部门采取的严密防控制度,给肉鸡业大洗牌的同时带来了后市的利好机遇,在各祖代肉种鸡企业尚未… 相似文献

Emergence of H5N1 highly pathogenic avian influenza in Democratic People's Republic of Korea 下载免费PDF全文
LIU Li-ling YANG Huan-liang GUO Fu-sheng WANG Xiu-rong DENG Guo-hua SHI Jian-zhong TIAN Guo-bin ZENG Xian-ying 《农业科学学报》2022,21(5):1534-1538
In the past decade, there has been extensive global surveillance for highly pathogenic avian influenza (HPAI) infection in both animals and humans, however, few studies on epidemiology of avian influenza in Democratic People's Republic of Korea (DPRK) were published. During the period 2013–2014, HPAI H5N1 viruses were detected with outbreaks in domestic poultry in DPRK. Phylogenetic analysis revealed that the hemagglutinin gene of all samples belonged to clade 2.3.2.1c with high homology. The HPAI H5N1 virus found in ducks at the Tudan Duck Farm in 2013 was might introduced by migratory birds and then led to the outbreaks on neighboring chicken farms in 2014. These data provide direct evidence for the transmission of avian influenza viruses from wild birds to waterfowl to terrestrial birds. Therefore, the monitoring and control of influenza virus in ducks must be given top priority, which are essential components to prevent and control HPAI. 相似文献

禽流感与人类健康 总被引:5,自引:0,他引:5
禽流感(avian influenza,AI)是由A型流感病毒(avian influenza virus)引起的一种禽类感染征或疾病综合症,高致病性禽流感(highly pathogenic avian influenza,HPAI)可引起禽类100%的死亡。由于抗原转变和抗原漂移,禽流感病毒是高度可变的。人禽流感是指高致病性禽流感病毒跨越物种界限,引起人类感染的一种新发传染病。目前,全球已发现H5N1、H7N7、H9N2等亚型禽流感病毒可感染人类。但目前还没有发现禽流感病毒具有在人群中相互传播的能力。对禽流感必须采用积极的预防策略。在加强监测的基础上,对家禽采用扑杀和免疫相结合的措施,可以有效地控制禽流感的流行。研制人类流感疫苗,是预防新的流感病毒株的流行的可靠保证。 相似文献

The H9N2 and H5N1 avian influenza viruses (AIVs) have been circulating in poultry in China and become endemic since 1998 and 2004, respectively. Currently, they are prevalent in poultry throughout China. This endemicity makes them actively involved in the emergence of the novel lineages of other subtypes of influenza viruses, such as the well-known viruses of the highly pathogenic avian influenza (HPAI) H5N2 and the 2013 novel H7N7, H7N9 and H10N8 subtypes, thereby threatening both the poultry industry and public health. Here, we will review briefly the prevalence and evolution, pathogenicity, transmission, and disease control of these two subtypes and also discuss the possibility of emergence of potentially virulent and highly transmissible AIVs to humans. 相似文献

Outbreaks of highly pathogenic avian influenza (HPAI) H5N 1 have taken place in 15 countries in Asia, Europe and Africa since 2003, and have caused great economic losses. Much likelihood has been considered as risk factors, of which wild birds are attributed as one of the main factors. This is related to the environmental deterioration in the wetland and expanse of human's activities in production. The risk analysis in this paper only focused on the effect of wild birds to HPAI, and confirmed the high risk of wild birds in the spread of AIVs. 相似文献

Vaccination for highly pathogenic avian influenza (HPAI) has been implemented in China for a decade, however, the virus is still present in poultry. A series of recombinant vaccines, Re-1 to Re-7, have been developed and used, and Re-8 will also be used in clinical settings to prevent the prevailing flu strains. The question remains, when can China eradicate the disease? Here, we review the epidemiology of H5 HPAI along with the development, usage and problems of vaccines. Further suggestions for controlling the disease in China are provided. 相似文献

试验通过对重组禽流感病毒(H5+H7)三价灭活疫苗(H5N1Re-11株+Re-12株+H7N9 H7Re-2株)在慢速型黄羽肉鸡上接种后产生抗体效价值的情况,来评价重组禽流感病毒(H5+H7)三价灭活疫苗(H5N1Re-11株+Re-12株+H7N9 Re-2株)对黄羽肉鸡预防高致病性禽流感疫病的效果。结果表明黄羽肉鸡在15日龄接种重组禽流感病毒(H5+H7)三价灭活疫苗(H5N1Re-11株+Re-12株+H7N9 H7Re2株),45日龄进行二次免疫,75日龄进行三免,产生H5N1Re-11株抗体滴度、H5N1Re-12株抗体滴度、H7N9 Re-2株抗体滴度都较高,从抗体消长规律来看对慢速型黄羽肉鸡出栏前都有很好的保护力。试验在黄羽肉鸡上接种重组禽流感病毒(H5+H7)三价灭活疫苗(H5N1Re-11株+Re-12株+H7N9 H7Re2株)首次免疫后14 d产生抗体有保护力,二免后28日龄抗体滴度达到高峰,对慢速型黄羽肉鸡有很好的保护力。 相似文献
