Genetic relatedness of high-level aminoglycoside-resistant enterococci isolated from poultry carcasses.
Approximately 46% (75/162) or poultry enterococci collected between 1999 and 2000 exhibited high-level resistance to gentamicin (minimum inhibitory concentration [MIC] > or = 500 microg/ml), kanamycin (MIC > or = 500 microg/ml), or streptomycin (MIC > or = 1000 microg/ml). Forty-one percent of the isolates were resistant to kanamycin (n = 67), whereas 23% and 19% were resistant to genramicin (n...
متن کاملMolecular epidemiology of high-level aminoglycoside-resistant enterococci isolated from patients in a university hospital in southern Italy.
OBJECTIVES We evaluated the genetic and molecular basis of high-level resistance to gentamicin and amikacin in 91 clinical isolates of Enterococcus faecalis and Enterococcus faecium in a university hospital in southern Italy from 1987 to 2003. METHODS Antibiotic susceptibility was evaluated by disc diffusion and microdilution methods. Genotyping was performed by PFGE and dendrogram analysis. ...
متن کاملAminoglycoside-resistant enterococci.
Thirty-four recent clinical isolates of Streptococcus faecalis were tested for sensitivity to amoxycillin, benzylpenicillin, streptomycin, kanamycin, gentamicin, tobramycin, and amikacin. Amoxycillin was two- to four-fold more active than benzylpenicillin and all strains were inhibited by low concentrations of the penicillins. The aminoglycosides were less active against the enterococci than we...
متن کاملThe prevalence and clonal expansion of high-level gentamicin-resistant enterococci isolated from blood cultures in a Dutch university hospital.
We studied the prevalence and clonality of high-level gentamicin-resistant enterococci (HLGRE) in a Dutch university hospital. Of 238 enterococcal strains isolated from blood cultures between 1991 and 1997, 57 were HLGRE. Genomic analysis of these strains revealed 19 different genotypes, two of which were encountered more frequently [type A (12/57), type B (23/57)]. The spread of these types la...
متن کاملFirst characterization of vancomycin-resistant enterococci from a Portuguese hospital.
Sir, Enterococci have been recognized as one of the leading causes of nosocomial infections, including urinary tract and bloodstream infections. One of the major reasons why these organisms survive in the hospital environment is their intrinsic resistance to several commonly used antibiotics and their ability to acquire resistance to most available antimicrobial agents. Resistance to glycopepti...
