The combination of penicillin G and dihydrostreptomycin acts additive and in some cases synergistic. Procaine penicillin G and benzathine penicillin G are small-spectrum penicillins with a bactericidal action against mainly Gram-positive bacteria like Clostridium, Corynebacterium, Erysipelothrix, Listeria, penicillinase-negative Staphylococcus and Streptococcus spp.
Dihydrostreptomycin is an aminoglycoside with a bactericidal action against mainly Gram-negative bacteria like E. coli, Campylobacter, Klebsiella, Haemophilus, Pasteurella and Salmonella spp.
