规模化蛋鸡场病原菌溯源与生物安全防控研究 总被引:1,自引:0,他引:1
细菌病严重威胁蛋鸡健康,以抗生素为主导的细菌病传统防控方式会导致病原菌耐药性严重、鸡蛋药物残留,影响蛋品安全。要保证蛋鸡产蛋期不用抗菌药物而又能生产出"无菌、无抗"的鸡蛋,是国内外技术难题。本团队以规模化蛋鸡场全封闭鸡舍为研究对象,基于PFGE、MLST、全基因组测序等技术,探明了蛋鸡病原菌的种类及基因组特征;对病原菌的耐药性研究表明,蛋鸡病原菌多重耐药严重,依靠药物防控的方式亟待转变;对规模化蛋鸡场细菌溯源研究结果表明,鸡舍生物媒介(鼠、苍蝇等)和非生物媒介(空气、饮水、饲料、鸡粪等)是蛋鸡病原菌的重要传染来源和传播途径;对规模化蛋鸡场生物安全量化评价结果表明,外部和内部生物安全权重高达92.2%。根据溯源和生物安全权重分析结果,提出了在规模化全封闭蛋鸡舍将蛋鸡细菌病从药物防控转变为生物安全防控的新策略;创新了规模化蛋鸡场细菌病防控的系统技术,实现蛋鸡规模养殖整个产蛋期不用抗生素,为生产"无菌、无抗"安全鸡蛋提供技术支撑。 相似文献

开展中美蛋鸡产业发展比较研究,有助于推进我国蛋鸡产业快速发展。在对比分析中美鸡蛋生产、国际贸易以及竞争力的基础上,梳理了影响蛋鸡产业竞争力提升的原因。研究发现:中国在蛋品出口类型以及出口量上与美国差距明显,虽然中国蛋鸡养殖在产蛋前成本、饲料费用等方面与美国相比不具优势,但中国蛋鸡养殖相对平稳。虽然中国蛋品国际市场占有率低于美国,但显示性比较优势指数表明中国蛋品国际竞争力略强于美国。中国与美国蛋鸡产业发展存在蛋鸡养殖集中化、标准化、自动化、机械化以及蛋鸡深加工等方面的差距。基于以上结论,提出了提高中国蛋鸡产业竞争力的对策建议。 相似文献

When early people made their appearance, zoonotic infectious diseases were already waiting, but epidemic diseases did not appear in human history until people began to live in large numbers under conditions of close contact, mainly during the last 10,000 years. Disease has decimated urban populations, conquered armies, and disrupted society. The focus here is on (1) the plague of Athens and the Black Death; (2) smallpox, influenza, and rabies; (3) avian influenza prion diseases, and foot & mouth disease; and (4) emerging and re-emerging diseases. All have veterinary public health associations. In Athens, Greece, in 430 BC, when the Spartans ravaged the countryside, hordes crowded into Athens so that orderly movements, space in which to live, and adequate supplies of food became impossible. Crowding of any population fosters disease transmission; chaos and disorder enhance it all the more. Out of northern Egypt came a terrible plague from across the Mediterranean Sea. The identity of the plague of Athens remains unsure, but the well-considered conclusion is Rift Valley Fever, a mosquito borne, viral zoonosis. The Black Death, also called the Plague, raged in Asia for centuries. In 1347, the Black Death was brought by a ship out of Asia to Sicily. The scenes of devastation were repeated throughout Europe, with 90% or more of the people dying in city after city. Influenza, too, has been a cause of periodic human epidemics, but the great pandemic of influenza occurred in the last months of World War I. In the years of highest occurrence, more than half the world's population became clinically infected. If veterinary public health had been born earlier, it could have led to elucidating the epidemiology of influenza and the plagues of Athens, Europe, and Asia. In turn, smallpox had also caused continual tragedy. In 1796, Edward Jenner began to harvest pustules of cowpox from children or infected cows and inject them into susceptible children. In 1980, the World Health Organization declared that smallpox had been eliminated from the world. Rabies, though, still strikes terror. A number of animal diseases, broadly termed emerging and re-emerging diseases, need surveillance because they have the potential to impact human health. From late in 2003 to 2007, the highly pathogenic H5N1 influenza virus in poultry infected at least 121 people and caused 62 deaths in four countries. The prion diseases, too, all have very high numbers in concentrated contacts. To control these diseases, veterinary public health is essential, with diagnosis, epidemiological surveillance, clinical manifestations, and prevention as primary measures. 相似文献

On 26th of july 2007 a new case of bluetongue was notified in the Netherlands and on 2nd of august 2007 foot-and-mouth disease was diagnosed in Surrey, England, which raised the threat of having both infections simultaniously in one area. Bluetongue and foot-and-mouth disease have a different pathogenesis, but symptoms may resemble each other at a later stage of infection. The pathogenesis and possible clinical symptoms of both infections are discussed and illustrated with pictures. 相似文献
