Research Abstract |
Efflux system overexpression is reported to contribute to Escherichia coli resistance to several antibiotics. This study investigated the correlation of antibiotic susceptibilities with overexpression of the efflux pump genes. We examined the expression level of efflux pump genes of E. coli. Significant relationships were demonstrated between overexpression of efflux pump genes and antibiotic resistance. This study demonstrated that increased expression of efflux pump genes can lead to fluoroquinolone resistance in E. coli causative UTI. These results contribute to our knowledge of the efflux system and raise the possibility of developing new agents such as efflux pump inhibitors (EPIs) to antibiotic-resistant E. coli.
