New silver-containing permanent polypropylene meshes were compared with a conventional lightweight polypropylene mesh commonly used in abdominal wall reconstructive surgery). Meshes (3 sq cm each) were placed onto the pre-fascia avascular plane and fixed in 7-wk-old male Sprague-Dawley Hairless rats (n=8 per mesh). Half of the implanted meshes (n=4) were directly inoculated with a suspension of Staphylococcus aureus-Xen 29 strain obtained from the exponential phase of growth (107 CFU). After 10 days, rats were euthanized and the engrafted prostheses together with the surrounding tissues were explanted by cutting around the area. Half of each implant was frozen for total RNA extraction. Once isolated, biological pools each containing 3 individual replicates of an equal quantity of RNA from each animal were constructed. Gene expression was analyzed in 3 different pools per condition using the Affymetrix Rat Gene 2.1 ST 16-Array Plate.
