    Background
    
    β-lactams interfere with PBP (penicillin binding protein) activity involved in the final phase of peptidoglycan synthesis. PBP’s are enzymes which catalyze a pentaglycine crosslink between alanine and lysine residues, providing additional strength to the cell wall. Without a pentaglycine crosslink, the integrity of the cell wall is severely compromised and ultimately leads to cell lysis and death. Resistance to β-lactams is commonly due to cells containing plasmid-encoded β-lactamases.

- Applications
  - Application Description
    
    Spectrum: Ertapenem Sodium has broad-spectrum activity targeting a wide spectrum of aerobic and anaerobic Gram-positive and Gram-negative bacteria.
    
    Microbiology Applications: Ertapenem Sodium is commonly used in clinical in vitro microbiological antimicrobial susceptibility tests (panels, discs, and MIC strips) against Gram-positive microbial isolates. Medical microbiologists use AST results to recommend antibiotic treatment options. Representative MIC values include:
    Staphylococcus aureus: 0.12 µg/mL – >16 µg/mL
    Escherichia coli: ≤ 0.008 - 0.5 µg/mL
    It is active against cephalosporin-resistant enteric organisms producing Extended-Spectrum Beta-Lactamases (ESBLs) and penicillin-resistant Streptococcus pneumoniae. It has restricted activity against nosocomial pathogens including Pseudomonas aeruginosa, Acinetobacter species, methicillin-resistant staphylococci and enterococci.
