Ten isolates showed a mutation in parE that was significantly associated with an increase in the MIC for fluoroquinolones.}, publisher = {American Society for Microbiolog}, title = {Contribution of a new mutation in parE to quinolone resistance in extended-spectrum-beta-lactamase-producing Escherichia coli isolates}, doi = {10.1128/JCM.01093-07}, author = {Sorlozano Puerto, Antonio and Gutiérrez Fernández, José and Jiménez Pacheco, Antonio and Luna Del Castillo, Juan De Dios and Martínez Torres, José Luis}, }
