Predicted genotypic aminoglycoside resistance was based on the presence of an Aac6′-Ib-cr or Aac6′-Ib gene (AAC(6′)-I) for amikacin and Aac3_IIa (AAC [ 3 ]-II) or AadB (ANT(2″)-I) for gentamicin. The x -axis shows the samples based on phenotypic resistance profiles (intermediate, sensitive, resistant) against gentamicin, and the bars show the number of isolates in the respective category that would have been predicted as sensitive (blue) or resistant (red) based on the genes as above
