  • Title: In vitro antibacterial efficacy of MONOCRYL plus antibacterial suture (Poliglecaprone 25 with triclosan).
    Author: Ming X, Rothenburger S, Yang D.
    Journal: Surg Infect (Larchmt); 2007 Apr; 8(2):201-8. PubMed ID: 17437365.
    Abstract:
    BACKGROUND: This study evaluated the in vitro efficacy of poliglecaprone 25 suture with triclosan against gram-positive and gram-negative bacteria. METHODS: Poliglecaprone 25 sutures with and without triclosan were tested for in vitro efficacy against Staphylococcus aureus, methicillin-resistant Staphylococcus aureus (MRSA), Staphylococcus epidermidis, methicillin-resistant Staphylococcus epidermidis (MRSE), Klebsiella pneumoniae, and Escherichia coli by a zone of inhibition assay. The suture also was tested against Escherichia coli in a colonization assay in a dynamic model simulating in vivo conditions. An in vitro triclosan diffusion assay and a sustained efficacy assay were performed by concurrent high-performance liquid chromatography and zone of inhibition assay. To assess stability, antibacterial efficacy testing was performed on samples held more than five months at elevated temperature. RESULTS: Poliglecaprone 25 suture with triclosan demonstrated significant in vitro efficacy against a range of bacteria. The suture sustained in vitro efficacy for 11 days, corresponding to the in vitro triclosan diffusion profile. CONCLUSION: Triclosan reduced in vitro colonization of poliglecaprone 25 suture by several strains of bacteria compared with untreated control sutures.
