Insertion sequence ISEcp1-like element connected with a novel aph(2'') allele [aph(2'')-Ie] conferring high-level gentamicin resistance and a novel streptomycin adenylyltransferase gene in Enterococcus.

Abstract excerpt

Enterococcus casseliflavus HZ95 is an enterococcus with high-level resistance to aminoglycosides. Nine genes responsible for high-level aminoglycoside resistance, including aac(6')-Ie-aph(2'')-Ia, aph(2'')-Ib, aph(2'')-Ic, aph(2'')-Id, aph(3')-IIIa, aac(6')-Ii, ant(3')-Ia, ant(4')-Ia and ant(6')-Ia, were not detected in HZ95. An 8 kb fragment from unconjugative plasmids of HZ95 was cloned, and expressed...
