Interplay Among Different Fosfomycin Resistance Mechanisms in Klebsiella Pneumoniae

Ortiz Padilla, M. Portillo Calderón, I. De Gregorio Iaria, Belén

The objectives of this study were to characterize the role of the uhpT, glpT, and fosA genes in fosfomycin resistance in Klebsiella pneumoniae and evaluate the use of sodium phosphonoformate (PPF) in combination with fosfomycin. Seven clinical isolates of K. pneumoniae and the reference strain (ATCC 700721) were used, and their genomes were...
