[Enzymatic assays of aminoglycoside antibiotics (author's transl)]

Adenylylating or acetylating enzymes, which are produced by grampositive and gramnegative bacteria resistant to aminoglycoside antibiotics, are useful tools in determining concentrations of aminoglycosides in patients' body fluids. Due to their accuracy, stability, versatility, fastness and inexpensiveness, enzymatic assays are the tests of choice for the routine determination of aminoglycoside concentrations.
