the incidence of virulence factors among 114 enterococcus faecalis and 35 enterococcus faecium strains from different clinical specimens were compared with those isolated from control groups. a few of the isolates expressed two or more of the following traits simultaneously: hemolysin, aggregation substance, gelatinase, dnase, hemagglutinin and antibiotic resistance. the frequencies of hemolysi...

Enterococci, which have useful biotechnological applications, produce bacteriocins, including those that exert anti-Listerial activity. The present study aimed to determine the antibiotic susceptibility patterns and antimicrobial activity of Enterococcus faecium strains isolated from human breast milk. The strains were identified using carbohydrate fermentation tests and ribotyping. Subsequentl...

The aim of this work was to characterize the functional properties of Enterococcus faecium strains identified after isolation from human faeces. Of these isolates, strain R13 showed the best resistance to low pH, bile salts, and survival in the simulated in vitro digestion assay, and demonstrated an important level of adhesion to hexadecane as a potential probiotic candidate. Analysis of the an...

BACKGROUND Vancomycin-resistant enterococci (VRE) are important nosocomial pathogens and food chain has been considered as an assumed source for dissemination of VRE to human. OBJECTIVES The presence of VRE isolates from food samples and typing of these isolates with Phene plate, a biochemical fingerprinting method, were investigated. MATERIALS AND METHODS Thirty samples of meat, chicken an...

BACKGROUND While enterococci resistant to multiple antimicrobials are spreading in hospitals worldwide, causing urinary tract, wound and bloodstream infections, there is little published data on these infections from Africa. METHODS We assessed the prevalence, susceptibility patterns, clinical outcome and genetic relatedness of enterococcal isolates causing bloodstream infections in children ...

Fifty-one pulsed-field gel electrophoresis types and 17 Tn1546 variants were identified among 101 Enterococcus faecium isolates recovered in three distant Portuguese hospitals. Intra- and interhospital dissemination of specific strains and Tn1546 types was detected, which might largely contribute to the endemicity of vancomycin-resistant E. faecium in Portuguese hospitals, as happened previousl...

Enterococci infections, have drawn attention of clinicians due to rapid increase in high level aminoglycoside resistance (HLAR). This predicts failure β-lactam antibiotic and combination, which is the current treatment choice for serious enterococci infections. led us investigate about prevalence HLAR our hospital setting Shimoga, Karnataka. All clinical samples received at Microbiology laborat...

Enterococci may display high level resistance to aminoglycosides, in which case synergy with cell-wall active antibiotics will be lost. All enterococcal blood culture isolates at Royal Brisbane Hospital have been screened by agar dilution for high level resistance to gentamicin and streptomycin since 1989. Of 110 isolates of Enterococcus faecalis, 16% displayed high level resistance to gentamic...

In the present study, a total of 55 European probiotic products were evaluated with regard to the identity and the antibiotic resistance of the bacterial isolates recovered from these products. Bacterial isolation from 30 dried food supplements and 25 dairy products, yielded a total of 268 bacterial isolates selected from several selective media. Counts of food supplements showed bacterial reco...

We studied the antimicrobial resistance and the molecular epidemiology of 99 enterococcal surveillance isolates from two hospitals of Brasilia, Brazil. Conventional biochemical tests were used to identify the enterococcal species and the disk diffusion method was used to determine their resistance profiles. Enterococcus faecalis (76%) and E. faecium (9%) were the most prevalent species. No ente...
