Jr. Hayes et al., High-frequency recovery of quinupristin-dalfopristin-resistant Enterococcus faecium isolates from the poultry production environment, J CLIN MICR, 39(6), 2001, pp. 2298-2299
The occurrence of resistance to the streptogramin quinupristin-dalfopristin
in Enterococcus faecium isolates from chickens on the Eastern Seaboard, wa
s evaluated. Quinupristin-dalfopristin resistance was found in 51 to 78% of
E. faecium isolates from the food production environment. The high level o
f resistance in this organism suggests that this reservoir of resistance ma
y compromise the therapeutic potential of quinupristin-dalfopristin.
