In Vitro Comparison of Four Aminoglycoside Antibiotics: Sisomicin, Gentamicin, Tobramycin, and BB-K8

Abstract
The activity of sisomicin, gentamicin, and tobramycin against 273 clinical bacterial isolates was about equal (except for greater activity of tobramycin against Pseudomonas ) and was greater than that of BB-K 8 as determined by antibiotic dilution methods in agar and broth.
