Aminoglycoside-modifying enzymes among Proteus mirabilis aminoglycoside-modifying enzymes, Proteus mirabilis, ESBL, plasmid-mediated resistance

conclusions the results of this study indicated that the genes encoding aminoglycoside-modifying enzymes are prevalent in a. baumannii isolates in the study region, which highlighted the necessity of considering preventive measures to control dissemination of these resistance genes. results antimicrobial susceptibility analysis showed that the highest resistance was towards beta−lactam antibiot...

conclusions this study detected multiple drug resistance (mdr) in p. aeruginosa including aminoglycosides. therefore, identification of drug resistance patterns in p. aeruginosa is of great importance in prevention and control of infections in burn patient centers. background the prevalence of resistance to aminoglycosides among p. aeruginosa isolates has increased all around the world. the res...

Several strains of Staphylococcus aureus and Staphylococcus epidermidis, exhibiting characteristic resistance patterns to aminoglycoside antibiotics, were examined. The aminoglycoside-modifying enzymes from these strains were purified by DEAE-Sephadex A-50 chromatography, affinity chromatography, and Sephadex G-100 gel filtration. Three enzymes, a 3'-phosphotransferase III (molecular weight, 31...

Background and Aims: Given the importance of aminoglycoside resistance in nosocomial and community infections caused by bacterial pathogenes such as Klebsiella pneumoniae (K. pneumoniae), the aim of this study was to determine the frequency of aac (6')- Ib and aac (3)- IIa, the genes encoding aminoglycoside modifying enzymes involved in aminoglycoside resistance. Material and Methods: A t...

The three classes of enzymes which inactivate aminoglycosides and lead to bacterial resistance are reviewed. DNA hybridization studies have shown that different genes can encode aminoglycoside-modifying enzymes with identical resistance profiles. Comparisons of the amino acid sequences of 49 aminoglycoside-modifying enzymes have revealed new insights into the evolution and relatedness of these ...
