Fig. 2From: Inter-species geographic signatures for tracing horizontal gene transfer and long-term persistence of carbapenem resistanceResistance mechanisms were phylogenetically dispersed but their carriage varied among closely related isolates. For E. hormaechei, E. coli, and K. pneumoniae, lineages are indicated in the inner ring with alternating shades of gray. Resistance mechanisms for each isolate are shown in the outer ring. The high-risk lineages K. pneumoniae ST-258 and E. coli ST-131 are marked. K. pneumoniae ST-15, which contained an example of likely nosocomial spread of porin-based CRE, is also marked with an asteriskBack to article page
