Mezlocillin

Mezlocillin is a broad-spectrum penicillin antibiotic. It is active against both Gram-negative and some Gram-positive bacteria.

Mechanism of action
Like all other beta-lactam antibiotics, mezlocillin inhibits the third and last stage of bacterial cell wall synthesis by binding to penicillin binding proteins. This ultimately leads to cell lysis.

 * Klebsiella species
 * ''Morganella morganii
 * Neisseria gonorrhoeae
