General description

Chemical structure: ß-lactam

Application

Cefotaxim has been used to find new residues involved in cefotaxime hydrolysis in CTX-M β-lactamases, to study antibiotic-susceptible and -resistant Streptococcus pneumoniae infections, and to study pneumococcal pneumonia and the pharmokinetics of various treatments. It may be used to study the effects of binding and inhibition of penicillin binding protein 2 (PBP2) on bacterial mucopeptide synthesis.

Biochem/physiol Actions

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.
Keep container tightly closed in a dry and well-ventilated place.

The CTX-M β-lactamases are an increasingly prevalent group of extended-spectrum β-lactamases (ESBL). Point mutations in CTX-M β-lactamases are considered critical for enhanced hydrolysis of cefotaxime. In order to clarify the structural determinants of the activity against cefotaxime in CTX-M β-lactamases

In an attempt to determine the susceptibility breakpoints for amoxycillin, co-amoxiclav and cefotaxime in pneumococcal pneumonia, a neutropenic mouse model was established and tested with two strains having different susceptibility to penicillins and cefotaxime. With a penicillin-sensitive strain (MIC/MBC =

The attribution of fresh produce to the overall community-associated exposure of humans to ESBL- or AmpC-producing bacteria is currently unknown. To address this issue, the prevalence of ESBL- and AmpC-producing Enterobacteriaceae on fresh produce produced in the Netherlands was determined.
