大肠杆菌耐药性研究进展

The research progress on mechanism of Drg-resistance of Escherichia coli

大肠杆菌是典型的革兰氏阴性杆菌,其引起的大肠杆菌病是一种常见疾病,在治疗过程中容易产生耐药性,且耐药谱广,耐药机制复杂,给养鸡业预防和治疗该病带来很大困难。大肠杆茵对抗生素的耐药问题是当前国内外研究的热点。本文对大肠杆菌耐药的现状以及产生耐药性机制的研究进行了综述,以便正确理解大肠杆菌耐药性的特点及其规律,从而为防治大肠杆菌耐药性的产生及合理用药提供理论依据。

E. coli is gram-negative bacteria, colibac111osls is a Kind oi common alsease. Escherichia coli strains showed high levels of resistance, resistance spectrum to expand, and multiple drug resistance. The drug resistant gene is complex and diverse. So the prevention and treatment of the disease bring a lot of difficulties. Antibiotic resistance is the current domestic and international research hot spot. The advances on mechanism of resistance and the present situation of E coli resistance are summarized. Thus the trend of the drug-resistance on the E coli resistance can be understood better and the basis for preventing the production of the resistant stains and using drugs reasonablely can be furtherly provided.
