Activity of amikacin against Mycobacterium avium complex under simulated in vivo conditions.
We studied the activity of amikacin against Mycobacterium avium complex strain 101 by using continuous-level, changing concentrations which simulated levels in serum in a patient, and pulsed exposures. Amikacin at a concentration of 5 or 15 micrograms/ml showed rapid bactericidal action following constant exposure of the organisms. With the in vitro model, using a peak concentration of 10 or 20 micrograms/ml, complete sterilization was obtained by day 7. In pulsed-exposure studies, a minimum period of contact of 72 or 96 h at a concentration of 10 micrograms/ml was needed for complete sterilization.
