Application

Methicillin is used to study bacterium susceptibility , methicillin-resistance in Staphylococcus aureus , and to inhibit cell-wall synthesis .

Biochem/physiol Actions

Methicillin inhibits cell wall synthesis. In Legionella pneumophila, methicillin causes the formation of membranous lesions through which cytoplasmic contents are lost .

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

This study aimed to determine the effect of selected essential oil compounds (EOCs) on the antibacterial activity of β-lactam antibiotics (βLAs) against methicillin-resistant Staphylococcus aureus (MRSA) strains. The following parameters were studied: antibiotic susceptibility testing, detection of mecA gene and

The response of Legionella pneumophila to antibiotics that inhibit cell-wall, protein and DNA synthesis was examined by electronmicroscopy, MIC estimations and viable counts. Ampicillin, cefotaxime, methicillin, erythromycin, rifampicin and ciprofloxacin, each used separately at 20 times their respective MIC values
