The primary mission of the USDA, Agricultural Research Service, Poultry Microbiological Safety Research Unit is to develop technology preventing commensal intestinal colonization of chickens by human bacterial enteropathogens, including Salmonella and Campylobacter. The different mechanisms of colonization and the wide variety of sources of these pathogens combined with the different factors that affect host susceptibility to colonization indicate that a multifaceted research approach will be required to control Salmonella and Campylobacter during poultry production. The working hypothesis is that only by delivering chickens free of Salmonella or Campylobacter to the processing plant can significant reductions in the number and levels of contamination of chickens leaving the plant with these pathogens be achieved. As the means are developed to substantially reduce or eliminate the intestinal colonization of chickens by these pathogens, the pathogen-free chickens can be delivered to the processing plant, thereby eliminating or at least reducing the prevalence and levels of Salmonella on processed broilers.
美国农业部农业研究局家禽微生物安全研究室的主要任务是研发技术,防止包括沙门氏菌和弯曲杆菌在内的人类细菌性肠道病原体在鸡的肠道内共生定殖。这些病原体的定殖机制各异、来源广泛,再加上影响宿主对定殖易感性的不同因素,这表明在家禽生产过程中控制沙门氏菌和弯曲杆菌需要采取多方面的研究方法。目前的工作假设是,只有将无沙门氏菌或弯曲杆菌的鸡送到加工厂,才能显著减少离开工厂的携带这些病原体的鸡的污染数量和水平。随着大幅减少或消除这些病原体在鸡肠道内定殖的方法的开发,无病原体的鸡可以被送到加工厂,从而消除或至少降低加工后肉鸡中沙门氏菌的流行率和水平。
