Enterococcus faecium

Vancomycin-resistant Enterococcus faecium (VREF) causes an infection common in US hospitals and is resistant to all commercially available antibiotics. Hospital outbreaks are rare in Europe, although VREF carriage among healthy individuals and livestock is common.

Vancomycin-resistant Enterococcus faecium (VREF) causes an infection common in US hospitals and is resistant to all commercially available antibiotics. Hospital outbreaks are rare in Europe, although VREF carriage among healthy individuals and livestock is common. A study from the National Institute of Public Health, Bilthoven, Netherlands, published in the online version of the Lancet on 13 March, suggests that genetic screening of E. faecium carriers could help eradicate this infection (Lancet 2001, 357:853-854).

Willems et al used DNA probes based on the esp virulence gene from E. faecalis, and screened (by Southern blotting) chromosomal digests of 120 VREF isolates associated with hospital outbreaks in the US, Europe and Australia. These were compared with 45 non-epidemic isolates. A particular subpopulation of E. faecium was associated with epidemic outbreaks in all three continents, and these epidemic strains carried a variant of the esp gene. The variant was not present...
