Sj. Kao et al., Detection of the high-level aminoglycoside resistance gene aph(2 '')-Ib inEnterococcus faecium, ANTIM AG CH, 44(10), 2000, pp. 2876-2879
A new high-level gentamicin resistance gene, designated aph(2")-Ib, was clo
ned from Enterococcus faecium SF11770. The deduced amino acid sequence of t
he 897-bp open reading frame of aph(2")-Ib shares homology with the aminogl
ycoside-modifying enzymes AAC(6')APH(2"), APH(2")-Ic, and APH(2")-Id. The o
bserved phosphotransferase activity is designated APH(2")-Ib.
