Type(s) of Resistant Mechanism of This Drug

  IDUE: Irregularity in Drug Uptake and Drug Efflux

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

Irregularity in Drug Uptake and Drug Efflux (IDUE)

Key Molecule: ABC transporter ATP-binding protein (ABCP) [1], [2]

• Molecule Alteration: Missense mutation; p.T450I
• Resistant Disease: Bacterial infection [ICD-11: 1A00-1C4Z]
• Experimental Note: Identified from the Human Clinical Data
• In Vitro Model: Escherichia coli TOP10; 83333
• In Vitro Model: Enterococcus faecium HM1070; 1352
• In Vitro Model: Enterococcus faecium UCN80; 1352
• Experiment for Molecule Alteration: Whole genome sequence assay
• Mechanism Description: ABC systems constitute one of the largest families of proteins, with most of them being involved in import and export, often called ABC transporters.Several of these class 2 ABC systems have been involved in MLS resistance, such as Msr-, Vga-, or Lsa-like proteins.The observed profile of cross-resistance to lincosamides, streptogramins A, and pleuromutilins conferred by Eat(A)v was similar to those conferred by other Lsa-like proteins.
