Fosfomycin mechanism

WebDec 11, 2024 · Three mechanisms of fosfomycin resistance have been described in E. coli so far: impaired drug uptake, enzymatic drug inactivation and target modification [ 2, 3, 5 ]. Impaired drug uptake Reduced drug uptake is the most frequent mechanism of resistance found both in in vitro mutants and clinical isolates [ 2, 3, 5 ]. WebAs fosfomycin is unique in its mechanism of action and less likely to select for co-resistance it may have a place in the treatment of both simple cystitis and more complicated UTI although literature on the latter is less common. Based upon literature reviewed, the following recommendations regarding the use of fosfomycin are proposed:

Despite its name (ending in -omycin) Fosfomycin is not a macrolide, but a member of a novel class of phosphonic antibiotics. Fosfomycin is bactericidal and inhibits bacterial cell wall biogenesis by inactivating the enzyme UDP-N-acetylglucosamine-3-enolpyruvyltransferase, also known as MurA. This enzyme catalyzes the committed step in peptidoglycan biosynthesis, namely the ligation of phosphoenolpyruvate (PEP) to the 3'-hydroxyl group of UDP-N-acetylglucosamine. This pyruvat… WebResistance Mechanism and MIC of Fosfomycin. The MIC of FRSA ranged from 64 to 2048 μg/mL, while the MIC of fosfomycin-sensitive S. aureus was 2 μg/mL.
