Abstract
The parC and gyrA genes of 73 ciprofloxacin-resistant and 6 ciprofloxacin-s usceptible Enterococcus faecium clinical isolates were partly sequenced. Al terations in ParC and GyrA, possibly in combination with other resistance m echanisms, severely restricted the in vitro activities of the nine quinolon es tested. For all isolates, clinafloxacin and sitafloxacin showed the best activities.
