Fluoroquinolone resistance in members of the Enterobacteriaceae family is mostly due to mutations in the quinolone resistance-determining regions of the topoisomerase genes. However, transferable genes encoding quinolone resistance have recently been described. The current methods for susceptibility testing are not

In the present study, we have synthesized 2-(substituted phenyl)-1H-imidazole (1-12) and (substituted phenyl)-[2-(substituted phenyl)-imidazol-1-yl]-methanone (13-26) analogues and screened them for their antimicrobial activity against gram positive, gram negative and fungal species. The results of antibacterial study indicated that compounds 15

Intubated patients frequently become colonized by Pseudomonas aeruginosa, which is subsequently responsible for ventilator-associated pneumonia. This pathogen readily acquires resistance against available antimicrobials. Depending on the resistance mechanism selected for, resistance might either be lost or persist after removal of

Inhibition of Nucleic Acid Synthesis by Antibiotics

Explore how antibiotics, particularly quinolones, inhibit nucleic acid synthesis by targeting topoisomerases, crucial for DNA replication processes.

抗生素对核酸合成的抑制作用

喹诺酮类药物是一类重要的抗生素，它们通过抑制拓扑异构酶来干扰DNA合成，最常见的是拓扑异构酶II（DNA旋转酶），它是一种参与DNA复制的酶。
