Sir,
A recent review by Smith et al.1 and associated correspondence2,3 raised important unresolved issues regarding which quinolones exert dual activity through gyrase and topoisomerase IV in Streptococcus pneumoniae. Dual action involves the substantial engagement of both enzyme killing pathways and is of particular interest in potentially limiting the emergence of resistance. Smith et al.3 concur with us2 that genetic studies are very important in identifying dual active drugs and agree that clinafloxacin is
