In over a decade (2002 to 2012) of Staphylococcus aureus surveillance testing on 62,195 isolates, dalbavancin was demonstrated to be active against isolates that were either susceptible or nonsusceptible to daptomycin, linezolid, or tigecycline. Nearly all (99.8%) multidrug-resistant methicillin-resistant S. aureus isolates were inhibited by dalbavancin at ≤0.12 μg/ml (MIC50/90, 0.06/0.06 μg/ml), the current U.S. Food and Drug Administration (U.S. FDA) breakpoint. Overall, only 0.35% of the monitored S. aureus isolates had a dalbavancin MIC of either 0.25 or 0.5 μg/ml (i.e., were nonsusceptible).
在对 62195 株金黄色葡萄球菌进行了超过十年(2002 年至 2012 年)的监测检测中,达巴万星对达托霉素、利奈唑胺或替加环素敏感或耐药的分离株均表现出活性。几乎所有(99.8%)的多药耐药性耐甲氧西林金黄色葡萄球菌分离株对达巴万星的抑制浓度均≤0.12μg/ml(MIC50/90,0.06/0.06μg/ml),这是目前美国食品和药物管理局(美国 FDA)的折点。总体而言,仅监测到金黄色葡萄球菌分离株中有 0.35%的达巴万星 MIC 为 0.25 或 0.5μg/ml(即耐药)。
