Abstract excerpt
PURPOSE: This study evaluated the impact of sub-MIC eravacycline exposure on carbapenem-resistant Acinetobacter baumannii with tigecycline MIC ≥ 8 µg/mL in clinical laboratory testing, and analyzed the resistance mechanisms. METHODS: 2144 A. baumannii isolates (2021–2024) from a Chinese tertiary hospital were analyzed for resistance trends. For 43 strains with tigecycline MIC ≥ 8 µg/mL, we conducted: (i) in vitro...
