The epidemiology of vancomycin-resistant enterococci (VRE) was studied in a
large tertiary-care hospital in northern Italy from February 1993 to Decem
ber 1999. Sixteen cases of bacteraemic and 17 cases of nonbacteraemic activ
e infections caused by VRE were recorded. Fifteen of the bacteraemic and fo
ur of the nonbacteraemic infections occurred in patients in the haematology
department, while the remainder were registered in other departments of th
e same hospital. Active surveillance for the presence of VRE in stools led
to identification of 51 noninfected carriers over the 1994-1999 period;, of
these, 32 were haematology patients and the remainder were patients admitt
ed to other departments. All VRE isolates carried the vanA gene. Forty-one
Enterococcus faecium isolates and eight Enterococcus faecalis isolates coll
ected in the 1993-1996 period were typed by pulsed-field gel electrophoresi
s. Twenty-nine isolates of Enterococcus faecium shared either indistinguish
able or strictly or possibly related patterns. Of these, 26 were isolated f
rom patients in the haematology department. This is believed to be the firs
t study on the epidemiology of VRE carried out in a large hospital in Italy
over a period of several consecutive years. It reports an increase in VRE
due to the epidemic spread of genetically related strains and sporadic infe
ctions or colonisation by unrelated VRE. It also documents the success of s
urveillance and of the measures adopted for preventing the spread of VRE in
patients at risk.
