General description

Chemical structure: ß-lactam

Application

Amoxicillin is used to study the oxygen dependent antimicrobial systems of polymorphonuclear leukocytes (PMNLs), the risk of resistance development in Helicobacter pylori, and various dosing strategies against Streptococcus pneumoniae and Pneumococcal pneumonia . It is also used to study the synthesis of bacterial cell walls at the level of peptidoglycan polymer chain cross-linking involving bacterial transpeptidase.

Biochem/physiol Actions

Amoxicillin is a broad-spectrum, β-lactam antibiotic. It is a 4-hydroxy analog of ampicillin with similar ranges of actions and utility to ampicillin. Amoxicillin inhibits the cross-linkage between linear peptidoglycan polymer chains that are the major component of both Gram-positive and Gram-negative bacteria.

Eighteen carbapenem-resistant, OXA-48-positive enterobacterial isolates recovered from Turkey, Lebanon, Egypt, France, and Belgium were analyzed. In most isolates, similar 70-kb plasmids carrying the carbapenemase gene bla(OXA-48) were identified. That gene was located within either transposon Tn1999 or transposon Tn1999.2, which
