These mutants have simultaneously acquired cross-resistance to kanamycin, gentamicin and neomycin but not to streptomycin or spectinomycin. Sensitivity of the mutant strains to the non-aminoglycoside antibiotics, ampicillin, tetracycline and polymyxin, was unaffected. The mutation responsible for amikacin resistance was mapped by P1 transduction and found to be tightly linked to strA, distal with respect to spcA and aroE. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-94-2-389
