Irregularity in Drug Uptake and Drug Efflux (IDUE)

Key Molecule: Protein QacZ (QACZ) [1]

• Resistant Disease: Enterococcal infection [ICD-11: 1A00-1C4Z]
• Molecule Alteration: Expression; Up-regulation
• Experimental Note: Discovered Using In-vivo Testing Model
• In Vitro Model: Enterococcus faecalis EF-SAVE1; 1244142
• In Vitro Model: Enterococcus faecalis V583ErmS; 1244142
• Experiment for Molecule Alteration: RT-PCR
• Experiment for Drug Resistance: MIC determination assay
• Mechanism Description: A derivative strain of V583, susceptible to erythromycin (V583ErmS), was complemented with pORI23 carrying the qacZ gene (strain EF-SAVE1). MICs of benzalkonium chloride, chlorhexidine and ethidium bromide were determined for the complemented strain and wild-type. The complemented strain, EF-SAVE1, presented a higher MIC of benzalkonium chloride (8 mg/L) than V583ErmS (4 mg/L); the MICs of chlorhexidine and ethidium bromide were the same for both strains, 4 mg/L and 16 mg/L, respectively. Expression of qacZ was found to be higher in EF-SAVE1 and constitutive, i.e. not inducible by any of the three tested bi.

Key Molecule: Multidrug resistance protein PmpM (PMPM) [2]

• Resistant Disease: Pseudomonas aeruginosa infection [ICD-11: 1A00-1C4Z]
• Molecule Alteration: Expression; Inherence
• Experimental Note: Identified from the Human Clinical Data
• In Vitro Model: Escherichia coli kAM32/pSTV28; 562
• Experiment for Molecule Alteration: PCR amplification and DNA sequence assay
• Experiment for Drug Resistance: MIC assay
• Mechanism Description: PmpM is a multi drug efflux pump coupled with hydrogen ions, which reduces the intracellular drug concentration and produces drug resistance.
