Seven amikacin-resistant strains of Enterobacteriaceae isolated in Slovakia and Germany were included in this study. The strains were also resistant in vitro to high levels of gentamicin, tobramycin, netilmicin and isepamicin. Phosphocellulose paper binding assays indicated that resistance to aminoglycosides was due to synthesis of aminoglycoside acetyltransferase AAC(6')-I a mechanism until now only identified in staphylococci and streptococci. This mechanism of aminoglycoside resistance has also been found in two isolates of Klebsiella pneumoniae from Germany. The substrate profile suggested that in addition to AAC(6')-I and APH(2"), several strains also produced AAC(3)-II. Aminoglycoside resistance was found to be transferable to Escherichia coli 3110 rifr in all isolates, and R plasmids of 36-45 MD were detected in donor and transconjugant strains. All isolated plasmids from transconjugants encoded resistance to aminoglycosides by genes encoding the enzymes AAC(6')-I and APH(2").

D004352 Drug Resistance, Microbial The ability of microorganisms, especially bacteria, to resist or to become tolerant to chemotherapeutic agents, antimicrobial agents, or antibiotics. This resistance may be acquired through gene mutation or foreign DNA in transmissible plasmids (R FACTORS).

D004755 Enterobacteriaceae A family of gram-negative, facultatively anaerobic, rod-shaped bacteria that do not form endospores. Its organisms are distributed worldwide with some being saprophytes and others being plant and animal parasites. Many species are of considerable economic importance due to their pathogenic effects on agriculture and livestock. Coliform Bacilli,Enterobacteria,Ewingella,Leclercia,Paracolobactrum,Sodalis
