Abstract

The basis of joint tolerance to beta-lactam and fluoroquinolone antibiotics in Escherichia coli mediated by hipA was examined. An antibiotic tolerance phenotype was produced by overexpression of hipA under conditions that did not affect the growth rate of the organism. Overexpressing hipA probably decreases the period in which bacteria are susceptible to the antibiotics by temporarily affecting some aspect of chromosome replication or cell division.

摘要

研究了由hipA介导的大肠杆菌对β-内酰胺类和氟喹诺酮类抗生素的联合耐受性基础。在不影响生物体生长速率的条件下,通过过表达hipA产生了抗生素耐受表型。过表达hipA可能通过暂时影响染色体复制或细胞分裂的某些方面来缩短细菌对抗生素敏感的时期。
