Abstract

ABSTRACT Multidrug-resistant clinical isolate Klebsiella pneumoniae BM4686 was highly resistant to 4,6-disubstituted 2-deoxystreptamines and to fortimicin. Resistance was due to the presence, on the 40-kb non-self-transferable plasmid pIP849, of the rmtF gene which was cotranscribed with the upstream aac ( 6 ′)- Ib gene. The deduced RmtF protein had 25 to 46% identity with members of the N7 G1405 family of aminoglycoside resistance 16S rRNA methyltransferases.
