Type(s) of Resistant Mechanism of This Drug

  DISM: Drug Inactivation by Structure Modification

Drug Resistance Data Categorized by Their Corresponding Diseases

ICD-01: Infectious/parasitic diseases

Non-tuberculous mycobacteria infection [ICD-11: 1B21]

Drug Resistance Data Categorized by Their Corresponding Mechanisms

Drug Inactivation by Structure Modification (DISM)

Key Molecule: OXA-23 carbapenemase (BLA OXA-23) [1]

• Molecule Alteration: Expression; Up-regulation
• Resistant Disease: Cutaneous bacterial infection [ICD-11: 1B21.4]
• Experimental Note: Identified from the Human Clinical Data
• In Vitro Model: Acinetobacter baumannii isolates; 470
• Experiment for Molecule Alteration: qRT-PCR
• Experiment for Drug Resistance: Broth microdilution method assay; Agar dilution method assay
• Mechanism Description: The isolate was resistant to antibiotics other than ampicillin-sulbactam and colistin, suggesting drug resistance due to carbapenemase production by OXA-23.carbapenem resistance in the isolated carbapenem-resistant A. baumannii strain was at least partially conferred by bla OXA-23-like carbapenemase.
