TABLE 2.

Distribution of co-occurring genotypic resistances to streptomycin and amikacin/kanamycin in a South African data set^a

Streptomycin genotype	Amikacin/kanamycin genotype
	WT	rrs 1400	eis promoter	Total
WT	67	2	2	71
rpsL	33	2	0	35
rrs (non-1400)	8	5	0	13
gidB	44	41b	0	85
Total	152	50	2	204

^aOf note, 7 isolates were identified to contain more than one streptomycin resistance mutation, as described in Table S4 in the supplemental material.

^bThe boldface type indicates the number of isolates with co-occurrence of gidB and rrs 1400 mutations that confer low-level streptomycin and high-level amikacin resistance.
