摘要: Background Divergence of bacterial populations into distinct subpopulations is often the result ecological isolation. While some studies have suggested existence Salmonella enterica subsp. subclades, evidence for these subdivisions has been ambiguous. Here we used a comparative genomics approach to define population structure enterica, and identify clade-specific genes that may be specialization.
