Abstract
We investigated the efficacy of Tachyplesin III alone or combined with piperacillin-tazobactam (TZP) to prevent biofilm formation in vitro and in a rat model of Pseudomonas aeruginosa ureteral stent infection. We have observed that in vitro TZP, in presence of Tachyplesin III, showed minimal inhibitory concentrations (MIC)s twofold and minimal bactericidal concentrations (MBC)s eightfold lower. The in vivo study showed that rats that received intraperitoneal TZP showed the lowest bacterial numbers. Tachyplesin III combined with TZP showed efficacies higher than that of each single compound. Coating ureteral stents with Tachyplesin III is able to inhibit bacterial growth up to 1000 times.
