The rabbit model of orthopaedic implant-associated infection (OIAI) involved the surgical placement of coated implants without (−/−) or with (Lin/Lin + Rif) antibiotics. N = 6 rabbits per experimental group. On day 7, the rabbits were killed and tissue (muscle/tendon), bone, and implant specimens were harvested and processed to determine ex vivo CFUs (mean and standard error of the mean [SEM]). LOD = limit of detection (for tissue: 2 × 103 CFUs; bone: 5 × 102 CFUs; implant: 2 × 101 CFUs).
Two-tailed Student t test.
