Linezolid Activity Compared to Those of Selected Macrolides and Other Agents against Aerobic and Anaerobic Pathogens Isolated from Soft Tissue Bite Infections in Humans

Linezolid was tested against 420 aerobes and anaerobes, including 148 Pasteurella isolates, by an agar dilution method. Linezolid was active against all Pasteurella multocida subsp. multocida and P. multocida subsp. septica isolates and most Pasteurella canis, Pasteurella dagmatis, and Pasteurella stomatis isolates. The MIC was ≤2 μg/ml for staphylococci, streptococci, EF-4b, Weeksella zoohelcum, Fusobacterium nucleatum, other fusobacteria, Porphyromonas spp., Prevotella spp., peptostreptococci, and almost all Bacteroides tectum isolates.
