The Analysis of Bacterial Results in the Kidney Perfusion Fluid and Bone Allografts in Human Multiorgan Donors.

In 19 young human multiorgan donors, we simultaneously analyzed the bacterial contamination of the kidney perfusion fluid and all retrieved bone allografts. Donor exclusion criteria were done according to the American and European Association of Tissue Banks excluding all patients with perforating wounds. The kidney perfusate revealed a contamination in 17 of 19 (89.5%) donors. Allograft testing demonstrated positive bacterial growth in 34 of 76 allografts (44.7%). Microorganisms originated from the normal skin flora and could be related to contamination during the harvesting procedure. In 5 cases we cultured identical bacterial subspecies in both cultures as a possible sign for systemic bacterial spreading during the multiorgan harvesting procedure.
