Molecular Phylogenetic Analysis of Sequences Identified Two Lineages of Strains Detected from Different Regions in Sudan Suggestive of Differential Evolution.

Background: () is ubiquitous among humans and one of the best-studied examples of an intimate association between bacteria and humans. Phylogeny and Phylogeography of strains are known to mirror human migration patterns and reflect significant demographic events in human prehistory. In this study, we analyzed the molecular evolution of strains detected from different tribes and regions of Sudan using gene and the phylogenetic approach.
