Relative Efficacy upon Pasteurella multocida of Various Antibiotics Aureomycin, Terramycin, Bacitracin, and Polymyxin B

SummaryThe bacteriostatic activity toward eight strains of Pasteurella multocida of aureomycin, terramycin, and bacitracin and the relative efficacy of four additional antibiotics, previously studied only singly, have been determined. It was found that the eight strains were very susceptible to penicillin, aureomycin, Chloromycetin, terramycin and polymyxin B but rather resistant to bacitracin and streptomycin.
