摘　　要：禽致病性大肠杆菌是毒力基因的贮存宿主,多种毒力因子的协同作用使其产生致病性,而耐药性的产生加大了对其防治的难度。本文主要对禽大肠杆菌毒力因子的种类、毒力特性及分子流行病学等研究进展进行了概述,为深入研究禽大肠杆菌病的致病机理和制定防控措施提供理论依据。Avian pathogenic Escherichia coli is the reservoir of virulence gene,synergism of various virulence factors result in pathogenicity,and the emergence of drug resistance has complicated its prevention and control. This paper summarizes the research progress of avian Escherichia coli virulence factors on types,virulence characteristics and molecular epidemiology,providing theoretical basis for the further study of the pathogenic mechanism of avian colibacillosis and formulion of its prevention and control measures.
