Susceptibility of Vascular Implants to Colonization in vitro by Staphylococcus aureus, Staphylococcus epidermidis, Enterococcus faecalis and Pseudomonas aeruginosa
Journal Title: Polish Journal of Microbiology - Year 2017, Vol 66, Issue 1
Abstract
We compared association of Staphylococcus aureus, Staphylococcus epidermidis, Pseudomonas aeruginosa and Enterococcus faecalis with nine vascular implants after co-culture. Vascular implants were composed of various materials such as warp knitted polyester (with or without gelatin and silver ions), expanded polytetrafluoroethylene and biological materials – surface treated porcine pericardial patch and Omniflow II. The lowest overall number of associated bacteria was detected for polytetrafluoroethylene implants and porcine pericardial patch. The highest overall number of associated bacteria was detected for Omniflow II implant. The major source of variation, i.e. primary factor influencing colonization, is the implant type (56.22%), bacterial species is responsible for only 1.81%, and interaction of those two factors – 13.09% of variation.
