Drug Resistance Data Categorized by Their Corresponding Mechanisms

Drug Inactivation by Structure Modification (DISM)

Key Molecule: Beta-lactamase (BLA) [1], [2]

• Molecule Alteration: Expression; Up-regulation
• Resistant Disease: Bacterial infection [ICD-11: 1A00-1C4Z]
• Experimental Note: Identified from the Human Clinical Data
• In Vitro Model: Escherichia coli strain DH5a; 668369
• In Vitro Model: Klebsiella pneumoniae strain HEL-1; 573
• Experiment for Molecule Alteration: Whole genome sequence assay
• Experiment for Drug Resistance: Agar dilution method assay
• Mechanism Description: The phenotype of Klebsiella pneumoniae HEL-1 indicates a plasmidic cephamycinase gene (blaCMY-2),which is responsible for cephamycin resistance.
