摘要
大肠杆菌感染是家禽在集约化养殖下经常爆发并迅速传播的一种疾病。该病能引起家禽局部或全身性感染,给广大养殖户带来巨大的经济损失。大肠杆菌既是家禽体内的正常菌群又是致病菌,不同类型的大肠杆菌其致病力不同。论文回顾了大肠杆菌目前常用的分型方法,包括常规的血清学分型,生化分型、药敏实验分型以及近年来随着生物学发展新兴的质粒图谱分型和脉冲场分型等,并就大肠杆菌现有的分型方法做一简要阐述,希望能为更好地研究和预防该病的发生,为确定不同菌株之间的关联性、细菌传染源的追踪和寻找传播途径提供更好、更合适的方法做参考。
Colibacillosis breaks out frequently and spreads quickly under the mode of poultry intensive feed.This disease can cause a local or systemic infection to poultry and a major economic loss to farmers.Colibacillus is not only the normal flora in vivo but also pathogen for poultry.Different types of colibacillus are changed in pathogenicity.This study reviewed the common methods in typing colibacillus which include classical methods as serotyping,biochemical test,plamids risistance monitoring and molecular methods as plasmid profile and Pulsed-Field GeI Electrophoresis etc.This paper elaborated the typing methods of colibacillus at present in order to find the relation and the source of different strains so that this disease can be prevented and controlled finally.
