[Spontaneous Listeria monocytogenes peritoneal infection complicating hepatic transplantation].

The incidence of listeriosis is increased in immunosuppressed patients. We report a case of spontaneous bacterial peritonitis with bacteraemia caused by Listeria monocytogenes in a 47-year old woman with liver transplantation. Complete recovery was achieved after amoxicillin and amikacin therapy. High doses of corticosteroids and OKT3 monoclonal therapy may have favoured the occurrence of infection. In liver transplant recipients, regular stool screening could be proposed, and trimethoprim-sulfamethoxazole antibioprophylaxy could be used when Listeria monocytogenes is isolated in stool culture or immunosuppressive therapy is increased.
