Abstract

This study aimed to evaluate the in vitro combination of farnesol and β-lactams against Burkholderia pseudomallei. A total of 12 β-lactamase-positive strains were tested according to CLSI standards. All strains were inhibited by farnesol, with MICs ranging from 75 to 150 μM. The combination of this compound with β-lactams resulted in statistically significant β-lactam MIC reduction (P ≤ 0.05). This study provides new perspectives for the use of farnesol combined with β-lactam antibiotics against strains of B. pseudomallei.

摘要

本研究旨在评估法尼醇与β-内酰胺类药物联合应用对伯克霍尔德菌的体外效果。根据 CLSI 标准,共检测了 12 株β-内酰胺酶阳性菌株。所有菌株均被法尼醇抑制,MIC 范围为 75-150μM。该化合物与β-内酰胺类药物联合使用可显著降低β-内酰胺类药物的 MIC(P≤0.05)。本研究为法尼醇联合β-内酰胺类抗生素治疗伯克霍尔德菌提供了新的思路。
