Extended Data Fig. 7: Clustering of fhuE by amino acid sequence.

MICs were done for 43 A. baumannii clinical isolates to determine if the isolates were hypersensitive to RBT in RPMI medium. 28 of the 33 isolates in the outer rings exhibit the hypersensitive phenotype (open circles) in RPMI (RBT MIC = 0.05 µg/mL). 9 of 10 isolates in the inner ring are not hypersensitive (filled-in shapes). Of the 41 carbapenem-resistant isolates tested, 26 of those are hypersensitive to RBT.
