This group includes streptomycin, dihydrostreptomycin, neomycin, framycetin, gentamicin, paromomycin, amikacin, tobramycin, and apramycin. All are bactericidal and active against Gram-negative organisms and some Gram-positive organisms, but not streptococci. Amikacin, gentamicin, and tobramycin are active against Pseudomonas aeruginosa. Aminoglycosides are taken up into bacteria by an oxygen-dependent process and are therefore inactive against anaerobic bacteria. They… Read More »
