Drug Inactivation by Structure Modification (DISM)

Disease Class: Escherichia coli infection [1]

• Resistant Disease: Escherichia coli infection [ICD-11: 1A03.0]
• Resistant Drug: Amikacin
• Molecule Alteration: Expression; Acquired
• Experimental Note: Discovered Using In-vivo Testing Model
• In Vitro Model: Escherichia coli strain DH5a; 668369
• In Vitro Model: Escherichia coli strain XLI-Blue; 562
• In Vitro Model: Providencia stuartii strain PR50; 588
• In Vitro Model: Providencia stuartii strain SCH75082831A; 588
• Experiment for Molecule Alteration: DNA sequencing assay
• Experiment for Drug Resistance: Microdilution plates assay
• Mechanism Description: E.coli DH5alpha/pR 1000 demonstrated an AAC(2')-Ia resistance profile,with gentamicin, tobramycin, netilmicin, and 6'-Nethylnetilmicin MICs increased over those seen with E.coli DH5alpha. In addition, E.coli DH5alpha/pR 1000 did not show an elevated 2'-N-ethylnetilmicin MIC (MIC was 0.25ug/ml). Therefore, pR1000 encoded an enzyme capable of acetylating 6'-N-ethylnetilmicin but not 2'-N-ethylnetilmicin, suggesting 2'-N-acetyltransferase activity. DH5alpha/pSCH4500, which contains a subcloned 1.3-kb fragment, also demonstrated an AAC(2')-Ia resistance profile.
