In this study, we observe that resistance of laboratory E. coli to two sublethal concentrations of the aminoglycoside kanamycin eventually produces a mutation that provides sufficient resistance to the antibiotic, while being of low cost as measured by growth or fitness in the absence of the antibiotic. This is only to be expected given enough time for selection to act as long as a less costly mutation (or a …

Kanamycin A - Wikipedia

Kanamycin A, often referred to simply as kanamycin, is an antibiotic used to treat severe bacterial infections and tuberculosis. It is not a first line treatment. It is used by mouth, injection into a vein, or injection into a muscle. Kanamycin is recommended for short-term use only, usually from 7 to 10 days.
