Disease Class: Lactobacillus casei infection [ICD-11: 1A00-1C4Z] [1]

• Resistant Disease: Lactobacillus casei infection [ICD-11: 1A00-1C4Z]
• Resistant Drug: Corticostatin
• Molecule Alteration: Expression; Up-regulation
• Experimental Note: Discovered Using In-vivo Testing Model
• In Vitro Model: Escherichia coli DH10beta; 316385
• In Vitro Model: Lactococcus lactis MG1363; 1358
• Experiment for Molecule Alteration: Real-time PCR
• Experiment for Drug Resistance: MIC assay
• Mechanism Description: Bce-like systems mediate resistance against antimicrobial peptides in Firmicutes bacteria. Lactobacillus casei BL23 encodes an "orphan" ABC transporter that, based on homology to BceAB-like systems, was proposed to contribute to antimicrobial peptide resistance. The transporter specifically conferred resistance against insect-derived cysteine-stabilized alphabeta defensins, and it was therefore renamed DerAB for defensin resistance ABC trans.
