Donor DNA is detected in recipient blood for years after kidney transplantation using sensitive forensic medicine methods.

Background: Transplanted vascularized organs shed passenger cells, normal constituents of whole organs, that migrate to recipient lymphoid tissues and produce microchimerism. These cells lyzed by recipient cytotoxic cells release cellular organelles into the recipient circulation. In addition, warm and cold ischemia as well as immune rejection of the transplanted organ or tissue bring about destructive changes in the graft parenchymatous cells.

[The molecular characteristic of Staphylococcus aureus and Staphylococcus epidermidis strains isolated from clinical sources].

The aim of study was the molecular characteristic of S. aureus and S. epidermidis isolates obtained from skin surface, wounds, deep tissues of hospitalized patients and from skin surface of non-hospitalized patients.
