vancomycin-resistant enterococci in brooklyn, new york: a moment in time. 199910585828
a comparison of the bacteria found on the hands of 'homemakers' and neonatal intensive care unit nurses.this prevalence study was conducted to compare the counts, types and antimicrobial resistance profiles of bacterial flora on the hands of individuals in the community to that of nurses at a nearby university teaching hospital, with an intense hand hygiene regimen. hand cultures were obtained from 204 individuals during a home visit and 119 nurses in two neonatal intensive care units (nicus). the mean total log counts of organisms were 5.73 and 5.24 for the homemakers [defined as the person (usua ...200312919763
american crows as carriers of vancomycin-resistant enterococci with vana gene.we studied the vana-carrying vancomycin-resistant enterococci (vre) isolated from american crows in the united states during the winter 2011/2012. faecal samples from crows were cultured selectively for vre and characterized. pulsed-field gel electrophoresis (pfge) and multilocus sequence typing (mlst) were used to examine epidemiological relationships of vana-containing vre. isolates were tested in vitro for their ability to horizontally transfer the vancomycin resistance trait. vre with the va ...201423919480
multiplicity of genetic backgrounds among vancomycin-resistant enterococcus faecium isolates recovered from an outbreak in a new york city hospital.a total of 182 vancomycin-resistant enterococcus faecium and 6 enterococcus faecalis inpatient isolates recovered during a 2-year period (1990-1992) in a new york city hospital were analyzed by molecular fingerprinting techniques, pulsed-field gel electrophoresis (pfge), of chromosomal smai digests combined with southern hybridization using vana and vanb2-specific dna probes. of the 180 isolates hybridizing with these probes, 153 carried the vana and 27 the vanb gene. as many as 21 different pfg ...19969158791
identification of chromosomal mobile element conferring high-level vancomycin resistance in enterococcus faecium.a clinical isolate of enterococcus faecium that contains a chromosomally encoded vana gene cluster, tn1546::is1251, transferred vancomycin resistance to the plasmid-free strain enterococcus faecalis jh2-2 during filter matings. hybridization of a vanhaxy probe to smai restriction-digested genomic dna separated by pulsed-field gel electrophoresis showed that the vana gene cluster was located on a 40-kb fragment in the original donor strain and on fragments of different sizes (150 to 450 kb) in th ...19958585724
clinical and molecular epidemiology of enterococcus faecalis bacteremia, with special reference to strains with high-level resistance to gentamicin.the objective of this study was to characterize the clinical and molecular epidemiology of enterococcus faecalis bacteremia, specifically that involving strains with high-level resistance to gentamicin (hlgr). episodes of e. faecalis bacteremia at the buffalo veterans affairs medical center from january 1986 to september 1989 were retrospectively identified. of 94 episodes, 45 (48%) were due to strains with hlgr. hemolytic activity was detected with greater frequency (85%) among the latter strai ...19957727634
incidence and clinical characteristics of enterococcus keratitis.to study the incidence, clinically relevant factors, and antibiotic sensitivity profile of cases of enterococcal keratitis presenting at the new york eye and ear infirmary between january 1, 1996, and december 31, 2005.200818724150
geographic sharing of ribotype patterns in enterococcus faecalis for bacterial source tracking.the limited host range of enterococcus faecalis may reduce its clonal diversity and thereby increase its geographic sharing of ribotype patterns. such sharing would be advantageous for bacterial source tracking (bst). we determined the geographic sharing of ribotype patterns in 752 ent. faecalis isolates obtained primarily from wastewater treatment plants in delaware (15 locations; 490 isolates), georgia (2 locations; 48 isolates), idaho (1 location; 118 isolates), new york (2 locations; 48 isol ...200717878566
