Prevalence of AMEs and correlation between antibiograms and AME genes in aminoglycoside resistant P. aeruginosa isolates

PCR results of AME genes	No. Of isolates (%)	Expected resistance	Observed result of aminoglycosides resistance phenotypes (no of isolates)
aac (6′)-1	10(18.5)	AMK	Unexpected resistance to GEN (3)
			As expected (7)
ant(2″)-1	9(16.6)	GEN	Unexpected resistance to AMK(1)
			As expected (8)
aac(6′)-I +ant(2″)-I	7(12.9)	AMK, GEN	Unexpected susceptibility to AMK (1)
			Unexpected susceptibility to GEN (1)
			Unexpected susceptibility to AMK+ GEN (1)
			As expected (4)
