Abstract / Zusammenfassung

A total of 368 bacterial pathogens, including 72 coagulase-positive and coagulase-variable staphylococci, 97 beta-haemolytic streptococci, 51 Escherichia coli, 75 Pasteurella multocida, 25 Mannheimia haemolytica, 25 Pseudomonas aeruginosa, and 23 Arcanobacterium pyogenes, were investigated for their susceptibility to the three combinations of antimicrobial agents lincomycin/spectinomycin (1/2), penicillin G/neomycin (1/1), and penicillin G/dihydrostreptomycin (1/1) in comparison to their susceptibility to the corresponding single substances. When comparing the minimum inhibitory concentrations (MICs) determined for any of the three combinations with those for the single substances, the lowest MIC of one of the two substances usually determined the MIC of the combination.This observation was made for all three combinations and all bacterial pathogens tested.Thus, it is assumed that the combination of lincomycin with spectinomycin as well as that of penicillin with either neomycin or dihydrostreptomycin resulted in an extended spectrum of target bacterial pathogens rather than in an increase in antimicrobial efficacy.
