RNAIII-inhibiting peptide affects biofilm formation in a rat model of staphylococcal ureteral stent infection.

چکیده
Ureteral stents coated with the quorum-sensing inhibitor RNAIII-inhibiting peptide (RIP) were implanted in rat bladders and shown to suppress Staphylococcus aureus formation on the stent and in urine and was especially effective when combined with teicoplanin. Coating ureteral stents with RIP thus increases the efficacy of teicoplanin in preventing ureteral stent-associated staphylococcal infections.

Suppression of drug-resistant Staphylococcal Infections by the quorum-sensing inhibitor RNAIII-inhibiting peptide.
Staphylococcus aureus and S. epidermidis are major causes of infection related to biofilm formed on indwelling medical devices. Such infections are common causes of morbidity and mortality and, because of biofilm resistance to antibiotics, are difficult to treat. The RNAIII-inhibiting peptide (RIP) (YSPWTNF-NH2) inhibits the pathogenesis of staphylococci by disrupting bacterial cell-cell commun...
متن کاملEfficacy of the Quorum Sensing Inhibitor FS10 Alone and in Combination with Tigecycline in an Animal Model of Staphylococcal Infected Wound
In staphylococci, quorum sensing regulates both biofilm formation and toxin production, moreover it has been demonstrated to be inhibited by RNAIII inhibiting peptide (RIP). Aim our study was to evaluate the in vitro activity and its in vivo efficacy of the combined administration of FS10, a novel RIP derivative, and tigecycline in an animal model of methicillin-resistant (MR) and methicillin-s...
متن کاملA chimeric peptide composed of a dermaseptin derivative and an RNA III-inhibiting peptide prevents graft-associated infections by antibiotic-resistant staphylococci.
Staphylococcal bacteria are a prevalent cause of infections associated with foreign bodies and indwelling medical devices. Bacteria are capable of escaping antibiotic treatment through encapsulation into biofilms. RNA III-inhibiting peptide (RIP) is a heptapeptide that inhibits staphylococcal biofilm formation by obstructing quorum-sensing mechanisms. K(4)-S4(1-13)(a) is a 13-residue dermasepti...
متن کاملAdvances in ureteral stents
Ureteral stents are commonly used in urology. Every urologist is familiar with the problems that are associated with stents including infection, encrustation, and bothersome symptoms. These problems limit and affect the use of ureteral stents which are necessary, even in light of the problems they can cause. New designs such as a helically cut ureteral stent which is designed to stretch and con...
متن کاملMutation of traP in Staphylococcus aureus has no impact on expression of agr or biofilm formation.
To investigate the regulatory role of traP (target of RNAIII-activating peptide) in Staphylococcus aureus, we generated traP mutations in the clinical isolates UAMS-1 and USA300. In neither case did mutation of traP affect expression of the accessory gene regulator (agr) or the ability to form a biofilm. We were also unable to confirm that mutation of traP in the prototype 8325-4 laboratory str...
