Cefoperazone is a third generation injectable cephalosporin agent and, like other cephalosporins, it inhibits bacteria cell wall synthesis. Cefoperazone is considered bactericidal and relatively resistant to bacterial beta-lactamases. The third generation cephalosporins retain much of the gram-positive activity of the first and secondgeneration agents, but in comparison, have much expanded gramnegative activity. As with the 2nd generation agents, enough variability exists with individual bacterial sensitivities that susceptibility testing is necessary for most bacteria. Usually only ceftazidime and cefoperazone are active against most strains of _Pseudomonas_ _aeruginosa_ .
In the United States, there are no cefotaxime products approved for veterinary species but it has been used clinically in several species when an injectable 3rd generation cephalosporin may be indicated.
