• Molecule Alteration: Missense mutation; p.D240G
• Resistant Disease: Bacterial infection [ICD-11: 1A00-1C4Z]
• Experimental Note: Identified from the Human Clinical Data

Key Molecule: Metallo-beta-lactamase (VIM1) [4]

• 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.

Key Molecule: Metallo-beta-lactamase (VIM1) [4]

• Molecule Alteration: Expression; Acquired
• Resistant Disease: Escherichia coli infection [ICD-11: 1A03.0]
• Experimental Note: Identified from the Human Clinical Data

• In Vitro Model: Pseudomonas aeruginosa 10145/3; 287
• Experiment for Molecule Alteration: DNA extraction and Sequencing assay

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.

Drug Resistance Data Categorized by Their Corresponding Mechanisms

Irregularity in Drug Uptake and Drug Efflux (IDUE)

Key Molecule: Bcr/CflA family efflux transporter (BCML) [6]

• Molecule Alteration: Expression; Inherence
• Resistant Disease: Klebsiella pneumoniae infection [ICD-11: CA40.1]
• Experimental Note: Identified from the Human Clinical Data
• In Vitro Model: Escherichia coli DH10B; 316385
• In Vitro Model: Escherichia coli strain NCTC 50192; 562
• In Vitro Model: Klebsiella pneumoniae strain ORI-1; 573
• Experiment for Molecule Alteration: PCR and hybridization experiments assay
• Experiment for Drug Resistance: Agar dilution technique assay
• Mechanism Description: Klebsiella pneumoniae ORI-1 strain harbored a ca. 140-kb nontransferable plasmid, pTk1, that conferred an extended-spectrum cephalosporin resistance profile antagonized by the addition of clavulanic acid, tazobactam, or imipenem. The gene for GES-1 (Guiana extended-spectrum beta-lactamase) was cloned, and its protein was expressed in Escherichia coli DH10B, where this pI-5. 8 beta-lactamase of a ca. 31-kDa molecular mass conferred resistance to oxyimino cephalosporins (mostly to ceftazidime). GES-1 is weakly related to the other plasmid-located Ambler class A extended-spectrum beta-lactamases (ESBLs).

Key Molecule: Bcr/CflA family efflux transporter (BCML) [6]

• Molecule Alteration: Expression; Acquired
• Resistant Disease: Klebsiella pneumoniae infection [ICD-11: CA40.1]
• Experimental Note: Identified from the Human Clinical Data
• In Vitro Model: Escherichia coli DH10B; 316385
• In Vitro Model: Escherichia coli strain NCTC 50192; 562
• In Vitro Model: Klebsiella pneumoniae strain ORI-1; 573
• Experiment for Molecule Alteration: PCR and hybridization experiments assay
• Experiment for Drug Resistance: Agar dilution technique assay
• Mechanism Description: Beta-Lactam MICs for k. pneumoniae ORI-1 and Escherichia coli DH10B harboring either the natural plasmid pTk1 or the recombinant plasmid pC1 were somewhat similar and might indicate the presence of an ESBL. In all cases, the ceftazidime MICs were higher than those of cefotaxime and aztreonam. Beta-Lactam MICs were always lowered by the addition of clavulanic acid or tazobactam, less so by sulbactam, and uncommonly by imipenem.

• Experiment for Molecule Alteration: PCR and hybridization experiments assay
• Experiment for Drug Resistance: Agar dilution technique assay
• Mechanism Description: Inhibition studies, as measured by IC50 values with benzylpenicillin as the substrate, showed that GES-1 was inhibited by clavulanic acid (5 uM) and tazobactam (2.5 uM) and strongly inhibited by imipenem (0.1 uM). Beta-Lactam MICs were always lowered by the addition of clavulanic acid or tazobactam, less so by sulbactam, and uncommonly by imipenem.

Key Molecule: OmpK37 (OMPK37) [16]

• Mechanism Description: Due to its porin deficiency, strain CSUB10R is more resistant to Beta-lactams than is parental strain CSUB10S. As expected, for k. pneumoniae CSUB10R expressing Ompk36 or Ompk35, the MICs reverted to values similar to those observed for strain CSUB10S.
