Sir,
The increasing resistance to fluoroquinolones among Streptococcus pneumoniae has been noted worldwide. Bacterial resistance to fluoroquinolones originates from point mutations at the highly conserved amino acid residues in the quinolone resistance-determining regions (QRDRs) of the gyrA subunit of DNA gyrase and the parC subunit of DNA topoisomerase IV.13 In addition, an active efflux mechanism may contribute
