Abstract
The quinolone resistance-determining regions of gyrA and parC of both quinolone-sensitive and quinolone-resistant Haemophilus parainfluenzae strains were amplified and sequenced. Similar to Haemophilus influenzae, resistance to quinolones in H parainfluenzae is associated with mutations in the quinolone resistance-determining regions of both gyrA and parC. The present study discusses the importance of this finding.
