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

Bacterial infection [ICD-11: 1A00-1C4Z]

Drug Resistance Data Categorized by Their Corresponding Mechanisms

Drug Inactivation by Structure Modification (DISM)

Key Molecule: Metallo-beta-lactamase (VIM1) [1]

• Molecule Alteration: Expression; Inherence
• Resistant Disease: Achromobacter xylosoxydans infection [ICD-11: 1A00-1C4Z]
• Experimental Note: Identified from the Human Clinical Data
• In Vitro Model: Escherichia coli; 668369
• In Vitro Model: Achromobacter xylosoxydans subsp. denitrificans AX-22; 85698
• In Vitro Model: Escherichia coli MkD-135; 562
• In Vitro Model: Pseudomonas aeruginosa 10145/3; 287
• Experiment for Molecule Alteration: DNA extraction and Sequencing assay
• Experiment for Drug Resistance: Macrodilution broth method assay
• Mechanism Description: A. xylosoxydans AX22 exhibited broad-spectrum resistance to Beta-lactams and aminoglycosides. The Beta-lactam resistance pattern (including piperacillin, ceftazidime, and carbapenem resistance) was unusual for this species, and the high-level carbapenem resistance suggested the production of an acquired carbapenemase. In fact, carbapenemase activity was detected in a crude extract of AX22 (specific activity, 184 +/- 12 U/mg of protein), and this activity was reduced (>80%) after incubation of the crude extract with 2 mM EDTA, suggesting the presence of a metallo-Beta-lactamase determinant.

Escherichia coli intestinal infection [ICD-11: 1A03]

Drug Resistance Data Categorized by Their Corresponding Mechanisms

Drug Inactivation by Structure Modification (DISM)

Key Molecule: Metallo-beta-lactamase (VIM1) [1]

• Molecule Alteration: Expression; Acquired
• Resistant Disease: Escherichia coli infection [ICD-11: 1A03.0]
• Experimental Note: Identified from the Human Clinical Data
• In Vitro Model: Escherichia coli; 668369
• In Vitro Model: Achromobacter xylosoxydans subsp. denitrificans AX-22; 85698
• In Vitro Model: Escherichia coli MkD-135; 562
• In Vitro Model: Pseudomonas aeruginosa 10145/3; 287
• Experiment for Molecule Alteration: DNA extraction and Sequencing assay
• Experiment for Drug Resistance: Macrodilution broth method assay
• Mechanism Description: Electroporation of Escherichia coli DH5alpha with the purified plasmid preparation yielded ampicillin-resistant transformants which contained a plasmid apparently identical to pAX22 (data not shown). DH5alpha(pAX22) produced carbapenemase activity (specific activity of crude extract, 202 +/- 14 U/mg of protein) and, compared to DH5alpha, exhibited a decreased susceptibility to several Beta-lactams.
