We studied the effect of pH (7.1, 6.3, and 5.8) on the in vitro susceptibilities of 59 isolates of Bacteroides fragilis and 60 isolates of other B. fragilis group species to trovafloxacin, ciprofloxacin, clindamycin, ampicillin-sulbactam, piperacillin-tazobactam, imipenem, and meropenem. For each agent tested the geometric mean MIC was highest at pH 5.8, intermediate at pH 6.3, and lowest at pH 7.1. The magnitude of the pH effect varied greatly among different antibiotics. These data show that an acidic pH decreases the in vitro susceptibilities of the B. fragilis group to several antibiotics.

ABSTRACT Tedizolid’s anaerobic activity is unappreciated. In this study, it was active against all 332 anaerobic isolates tested at ≤2 μg/ml except Bilophila wadsworthia and was more active than linezolid against Bacteroides fragilis group species (MIC90, 1 μg/ml versus 2 to 4 μg/ml). Tedizolid was active against Gram-positive anaerobes (MIC90 for clostridia, 0.25 to 1 μg/ml; MIC90 for anaerobic cocci, ≤0.06 to 0.25 μg/ml). Our data coupled with clinical reports indicate that clinicians should consider its use in mixed infections where Staphylococcus aureus and anaerobes are involved.
