The combination of penicillin G and dihydrostreptomycin acts 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.
