General description
Chemical structure: β-lactam
Biochem/physiol Actions
Mode of Action: Inhibits bacterial cell wall synthesis.
Cefotaxim inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs) which inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell walls. As a result, bacteria lyse due to cell wall autolytic enzymes.
Other Notes
Broad spectrum third generation cephalosporin antibiotic.

The accurate identification of β-lactamases produced by Enterobacteriaceae is a major challenge in clinical laboratories in order to optimize antimicrobial treatment and patient care. We describe here a rapid voltammetric-based method to detect and to discriminate β-lactamase activity in Enterobacteriaceae
