Gentamicin

Gentamicin inhibits many strains of staphylococci and coliforms and other gram-negative bacteria. It is a synergistic companion with beta-lactam antibiotics, against Pseudomonas, Proteus, Enterobacter, Klebsiella, Serratia, Stenotrophomonas, and other gram-negative rods that may be resistant to multiple other antibiotics.

Gentamicin is also used concurrently with penicillin G for bactericidal activity in endocarditis due to viridans streptococci. Creams, ointments, or solutions gentamicin sulfate are for the treatment of infected burns, wounds, or skin lesions.
