چکیده

background: bacteremia due to enterococcus faecalis is usually caused by strains resistant to most antibiotics. effective management of the disease is dependent on rapid detection and characterization of the bacteria, and determination its sensitivity pattern to antimicrobial drugs. the aim of this study was to investigate a more rapid and reliable assay for simultaneous diagnosis of enterococcal bacteremia and its sensitivity pattern to antimicrobial drugs. methods: several bacterial suspensions with different content of two standard strains of enterococcus faecalis resistant to vancomycin were used for inoculation to defibrinated sheep blood samples. pcr and routine assay was performed on all blood samples with different bacterial content. results: routine assay and pcr for all inoculated blood samples with ≥5 cfu/ml was positive. mean time for pcr and routine assays was 10 hours and 5 days, respectively. conclusion: pcr is a more rapid and sensitive assay for simultaneous detection and characterization for enterococcus faecalis, and determination of its sensitivity pattern to vancomycin.

Identification and molecular characterization of Van A-type vancomycin-resistant Enterococcus faecalis in Northeast of Brazil.

The isolation of vancomycin resistant enterococci (VRE) in Brazil has rapidly increased, following the world wide tendency. We report in the present study the first isolation of vancomycin resistant Enterococcus faecalis (VRE) in the Northeast of Brazil. The four VRE isolates were characterized for antimicrobial susceptibility, genotypic typing by macro restriction of chromosomal DNA followed b...
