Plasmid-mediated gentamicin resistance of Pseudomonas aeruginosa and its lack of expression in Escherichia coli.
We isolated 11 nonconjugative plasmids mediating resistance to aminoglycoside antibiotics, including gentamicin, from Pseudomonas aeruginosa strains. Their genetic properties were investigated in both P. aeruginosa and Escherichia coli transformants. The plasmid molecular weights ranged from 11 x 10(6) to 24 x 10(6). A low level or complete absence of gentamicin resistance was observed when the...
متن کاملBerberine Is a Novel Type Efflux Inhibitor Which Attenuates the MexXY-Mediated Aminoglycoside Resistance in Pseudomonas aeruginosa
The emergence and spread of multidrug-resistant P. aeruginosa infections is of great concern, as very few agents are effective against strains of this species. Methanolic extracts from the Coptidis Rhizoma (the rhizomes of Coptis japonica var. major Satake) or Phellodendri Cortex (the bark of Phellodendron chinense Schneider) markedly reduced resistance to anti-pseudomonal aminoglycosides (e.g....
متن کاملContribution of the MexXY multidrug transporter to aminoglycoside resistance in Pseudomonas aeruginosa clinical isolates.
MexXY is an aminoglycoside-inducible multidrug transporter shown to contribute to intrinsic and acquired aminoglycoside resistance in laboratory isolates of Pseudomonas aeruginosa. To assess its contribution to aminoglycoside resistance in 14 clinical isolates demonstrating a panaminoglycoside resistance phenotype unlikely to be explained solely by aminoglycoside modification, expression of mex...
متن کاملAminoglycoside 6'-N-acetyl-transferase of Pseudomonas aeruginosa: structural requirements of substrate.
Sir: As reported previously,1-5) aminoglycoside 6'-N-acetyltransferases [AAC(6')] in R factorcarrying Escherichia coli and Pseudomonas aeruginosa are involved in the mechanism of resistance to several aminoglycoside antibiotics such as kanamycin, kanamycin B, 3',4'dideoxykanamycin B (DKB) and ribostamycin. Gentamicin C1a and sisomicin are acetylated by these enzymes6,7). In this paper, we repor...
متن کاملThe Role of aac(6)-IIa and ant(2'')-Ia Genes and the Presence of Class 1 Integrons in Resistance of Pseudomonas Aeruginosa Clinical Isolates against Aminoglycosides
Background and purpose: The aminoglycoside modifying enzymes (AMEs) and class 1 integrons in clinical isolates of pseudomonas aeruginosa are the major factors leading to rapid spread of antibiotic resistance. The aim of the present study was to investigate the frequency of aac(6)-IIa, ant(2'')-Ia, and class 1 integrons in clinical isolates of pseudomonas aeruginosa. Materials and methods: For ...
متن کاملComparative in vitro activities of enoxacin (CI-919, AT-2266) and eleven antipseudomonal agents against aminoglycoside-susceptible and -resistant Pseudomonas aeruginosa strains.
The in vitro activity of enoxacin (CI 919, AT 2266), a new oral quinolone carboxylic acid compound, was compared with those of gentamicin, tobramycin, amikacin, azlocillin, piperacillin, aztreonam, moxalactam, imipenem, cefsulodin, ceftazidime, and cefoperazone against 101 aminoglycoside-susceptible and 105 aminoglycoside-resistant Pseudomonas aeruginosa strains. Among these 206 P. aeruginosa i...
