Abstract excerpt
Some of the most dangerous pathogens such as Mycobacterium tuberculosis and Yersinia pestis evolve clonally. This means that little or no recombination occurs between strains belonging to these species. Paradoxically, although different members of these species show extreme sequence similarity of orthologous genes, some show considerable intraspecies phenotypic variation, the source of which remains elusive. To...
