Of pseudomonas aeruginosa isolates, 54% were found to be sensitive to ticarcillin, 74% to ticarcillin/clavulanic acid, whereas 24% of Escherichia coli isolates were sensitive to ticarcillin (susceptible + moderately susceptible), and 94% to ticarcillin/clavulanic acid. It was determined that 23% of P. aeruginosa and 4% of E. coli isolates brought about a zone diameter equal to or below 15 mm against piperacillin/tazobactam. As a result, P. aeruginosa and E. coli isolates were found to be susceptible to both of the beta-lactam/beta-lactamase inhibitor combinations.trinfo:eu-repo/semantics/closedAccessEscherichia ColiPiperacillin/TazobactamPseudomonas AeruginosaTicarcillin/Clavulanic AcidTicarillinArticle31147512-s2.0-0030741307N/A
