[Risks of infection in xenotransplantation: what are they and how are they to be controlled?]

Abstract

Porcine grafts are a potential source of pathogenic agents capable of contaminating the recipient. The spread of porcine retroviruses in the patient's tissues is a major risk that must be rigorously evaluated. The control of the microbiological state of the pig donor, concerning retroviruses and other pathogens, is the necessary condition for controlling this risk.
