L. asiaticus’ bacterium and provided a therapeutically effective level of control for a much longer period of time than when administering either antibiotic separately.In contrast, brief treatment with streptomycin failed to affect subsequent killing by penicillin. These findings suggest that the synergism of penicillin with streptomycin depends on the damaging effect of penicillin on the cell membrane, which promotes further damage by streptomycin and increases its subsequent access to intracellular sites.
