A 17-year-old male patient with extrahepatic biliary atresia underwent
an orthotopic liver transplantation in September 1994. In blood cultu
res drawn in November and (6 weeks later) December 1994, from bile sec
retions in May 1995, stool in June 1995 an wound abscess in August 199
5, ampicillin . resistant Enterococcus faecium was isolated. Pulsed-fi
eld gel electrophoresis demonstrated the clonal identity of the isolat
es. To our knowledge, repeated infections with the same E, faecium str
ain over a period of 9 months have not been described before. As multi
ple-resistant enterococci may colonize and reinfect liver transplant r
ecipients for such a long time, preoperative antibiotic therapy should
be administered cautiously in order not to select these organisms.
