In Vitro Susceptibility Test of Different Clinical Isolates against Ceftriaxone.

Objectives: Because of the prevailing penicillin resistance in microorganisms, broad spectrum cephalosporins are used empirically specially in developing countries. The aim of this study is to determine the susceptibility pattern of different gram positive and gram negative pathogens against third generation cephalosporin-ceftriaxone to explore the existing effectiveness of this antibiotic.

Methods: 180 clinical isolates of different gram positive and gram negative pathogens including P.
