quantitative phosphorylation of amikacin in vitro by a sonicate of the transconjugant strain inactivated the antibiotic , as measured by bioassay , and the phosphorylated drug failed to produce synergism when combined with penicillin against a strain sensitive to penicillin-amikacin synergism.no differences were found in the sensitivity of ribosomes from a sensitive and resistant strain when examined in vitro using polyuridylic acid directed [ ( 14 ) c ] -phenylalanine incorporation in the presence of streptomycin , kanamycin , or amikacin .
