Abstract
The purpose of this study was to evaluate bacterial adhesion and early colonization on a composite consisting of bioactive glass (BAG) particles and copolymer of e-caprolactone/D, L-lactide. Materials were incubated with suspensions of both type strains and clinical isolates of Streptococcus pneumoniae, Haemophilus influenzae, and Pseudomonas aeruginosa for 30 minutes (adhesion) and 4 hours (colonization). Clear differences exist in the microorganisms' ability to adhere on the experimental materials. However, the presence of BAG particles does not inhibit bacterial adhesion, but early colonization of the materials with P. aeruginosa was inhibited by the addition of 90-315 mu m BAG particles.
