Ceftolozane-tazobactam (C/T) is a novel cephalosporin within vitro activity againstPseudomonas aeruginosa that is resistant to extended-spectrum penicillins and antipseudomonal cephalosporins. In order to assess the antimicrobial effect of C/T in treatment ofPseudomonas pneumonia, we investigated the pharmacokinetics and efficacy of C/T in persistently neutropenic rabbits.Pseudomonas pneumonia was established by direct endotracheal inoculation.
