An elderly woman, admitted to the intensive care unit of a large unive
rsity teaching hospital, was found to be colonized with vancomycin-res
istant enterococci leading to the temporary closure of the unit. She h
ad acquired the organism nosocomially, most likely from an environment
al source, which had been contaminated when the toilet of a former pat
ient, also colonized with vancomycin-resistant enterococci, had become
blocked and overflowed throughout his and the adjoining room. This is
the first report of a hospital toilet as the transmission vector for
vancomycin-resistant enterococci.
