[In vitro and in vivo antimicrobial activity of cefuroxime cefamandole and cephalexin on freshly isolated strains of Gram-positive and Gram-negative bacteria]

The Authors studied the antibacterial activity "in vitro" and "in vivo" of cefuroxime, cefamandole and cephalexin on the Gram-positive and Gram-negative bacterial strains of recent isolation. The results showed a greater antibacterial activity of cefuroxime than the other two cephalosporins, mainly on the Gram-negative beta-lactamase producing bacterial strains.
