[Infectious complications after liver transplantation].

Infections after liver transplantation are frequent and represent the first cause of mortality. Bacterial and fungal infections are favourized by preoperative clinical status, surgical conditions, degree of immunosuppression, and surgical complications. Perioperative antibiotics and, for patients at risk, antifungal prophylaxis, reduce their indicidence. Viral infections are attributed principally to CMV. Prophylaxis against CMV with immunoglobulins can be suggested for patients at risk. Curative antiviral treatment is always effective.
