Origin in Acinetobacter guillouiae and Dissemination of the Aminoglycoside-Modifying Enzyme Aph(3′)-VI
The amikacin resistance gene aphA6 was first detected in the nosocomial pathogen Acinetobacter baumannii and subsequently in other genera. Analysis of 133 whole-genome sequences covering the taxonomic diversity of Acinetobacter spp. detected aphA6 in the chromosome of 2 isolates of A. guillouiae, which is an environmental species, 1 of 8 A. parvus isolates, and 5 of 34 A. baumannii isolates. Th...
متن کاملMolecular Epidemiology of Aminoglycosides Resistance in Acinetobacter Spp. with Emergence of Multidrug-Resistant Strains
BACKGROUND Acinetobacter spp. is characterized as an important nosocomial pathogen and increasing antimicrobial resistance. Our aim was to evaluate antimicrobial susceptibility and aminoglycosides resistance genes of Acinetobacter spp. isolated from hospitalized patients. METHODS Sixty isolates were identified as Acinetobacter species. The isolates were tested for antibiotic resistance by dis...
متن کاملDetection of aac(6')-I genes in amikacin-resistant Acinetobacter spp. by PCR.
The distribution of aac(6')-I genes in 62 strains of Acinetobacter spp. resistant to amikacin, netilmicin, and tobramycin and susceptible to gentamicin, a phenotype compatible with synthesis of an AAC(6')-I enzyme, was studied by PCR and by DNA hybridization. Both methods gave similar results. Among the 51 Acinetobacter baumannii strains, aac(6')-Ib was found in 19 isolates and aac(6')-Ih was f...
متن کاملRapid determination of quinolone resistance in Acinetobacter spp.
In the treatment of serious bacterial infections, the rapid institution of appropriate antimicrobial chemotherapy may be lifesaving. Choosing the correct antibiotic or combination of antibiotics is becoming very important, as multidrug resistance is found in many pathogens. Using a collection of 75 well-characterized multidrug-resistant (MDR) Acinetobacter sp. isolates, we show that PCR followe...
متن کاملPrevalence of Aminoglycoside Resistance Genes in Acinetobacter baumannii Isolates
BACKGROUND Acinetobacter baumannii is one of the major causes of nosocomial infections and is resistant to most available antibiotics. Aminoglycosides remain as drugs of choice for treatment of Acinetobacter infections yet resistance to aminoglycosides has increased in the recent years. OBJECTIVES The present study investigated the prevalence of genes encoding aminoglycoside-modifying enzymes...
