Disease Class: Enterococcus faecium meningitis [1]

• Resistant Disease: Enterococcus faecium meningitis [ICD-11: 1D01.2]
• Resistant Drug: Plazomicin
• Molecule Alteration: Expression; Inherence
• Experimental Note: Identified from the Human Clinical Data
• In Vitro Model: Enterococcus faecium SF11770; 1352
• In Vitro Model: Escherichia coli kHE5-2a; 562
• In Vitro Model: Escherichia coli strain DH10b(pMW119); 316385
• Experiment for Molecule Alteration: PCR
• Mechanism Description: High-level gentamicin resistance (MIC >= 500 ug/ml) in enterococci is predominantly mediated by aac(6')-Ie-aph(2")-Ia, which encodes the bifunctional aminoglycoside-modifying enzyme AAC(6')-APH(2"). Found less commonly is aph(2")-Id, another gene recently reported to be associated with high-level gentamicin resistance in enterococci.
