鸡致病性大肠杆菌耐药性的研究进展

大肠杆菌是一种常见致病菌，近年来，大肠杆菌的耐药株不断增多，特别是多重耐药株的大量出现，使其治疗变得十分困难。本文对鸡致病性大肠杆菌耐药现状以及产生耐药性机制的研究作以综述，以期为进一步研究鸡大肠杆菌病的综合防治提供依据。

Research progress on tolerance to pathogenic escherichia coli in chicken

Escherichia coli is a common pathogenic bacteria. In recent years, resistant strains of escherichia coli was growing, especially multiple drug-resistant strains, the veterinary clini-cal treatment of escherichia coli disease became very difficult. The status of pathogenic esche-richia coli resistance and resistance mechanism was reviewed in this paper, in order to provide ba-sis for the further study the prevention and control of the poultry escherichia coli disease.
