Evolution and recombination of the plasmidic qnr alleles.

Journal of molecular evolution - 1 Jul 2008

Baquirin Mia H C, Barlow Miriam

Abstract excerpt

qnr is an important and recently emerged plasmidic fluoroquinolone resistance gene. Numerous qnr alleles have been detected, but previous studies have suggested that there is little functional divergence among them. We performed phylogenetic analysis of representative qnr alleles and examined the phylogeny for the occurrence of positive selection (d(N)/d(S)). Positive selection rarely occurred near the tips of...
