broth microdilution in 714 blood isolates from 14 hospitals in Turkey. Isolates included
Escherichia coli (n= 320), Klebsiella spp.(n= 294), Enterobacter spp.(n= 69), Serratia
marcescens (n= 20), and Citrobacter spp.(n= 11). Isolates resistant to older aminoglycosides
(n= 240) were screened for aminoglycoside modifying enzyme genes: aac (6′)-Ib, aac (3)-
Ia, aac (3)-IIa, ant (2 ″)-Ia. Isolates with high MICs for plazomicin (n= 41) were screened for …
