Molecular signatures identify a candidate target of balancing selection in an arcD-like gene of Staphylococcus epidermidis.

Abstract excerpt

A comparative population genetics study revealed high levels of nucleotide polymorphism and intermediate-frequency alleles in an arcC gene of Staphylococcus epidermidis, but not in a homologous gene of the more aggressive human pathogen, Staphylococcus aureus. Further investigation showed that the arcC genes used in the multilocus sequence typing schemes of these two species were paralogs. Phylogenetic analyses...
