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 deduc...
