Background: Clinical xenotransplantation holds great promise by providing one solution to the shortage of human organs for transplantation, while also posing a potential public health threat by facilitating transmission of infectious disease from source animals to humans. One potential vector for infectious disease transmission is healthcare workers (HCW) who are involved in administering xenotransplantation procedures. Methods: In this study, we studied 49 healthcare workers involved in the care of two subjects who participated in a study of porcine liver perfusion as treatment of fulminant hepatic failure. We looked for serologic and virologic evidence of transmission of porcine endogenous retrovirus, and found that HCW had no evidence of infection. Conclusions: Results of our survey demonstrate that application of standard precautions may be sufficient to prevent transmission of porcine endogenous retrovirus, an agent of concern in ex vivo xenotransplantation products.
