this study investigated the antibacterial resistance among enterococci isolated in tehran hospitals. a total of 277 enterococcus faecalis, 123 enterococcus faecium and 13 isolates of other enterococcal strains were collected from 1 march 2002 to 15 april 2004 from three teaching hospitals of tehran university of medical sciences. the minimum inhibitory concentrations (mic) of tested antibiotics...

aim & background : enterococci infections are public health growing concern due to the glycopeptide antibiotics resistance especially vancomycin. genes, vana, b, and h, are contributed to the influence of vancomycin-resistant enterococci (vre). this investigation aims at exploring the vre frequency and the rate of each genes in isolated enterococci from gastroenteritis patients in central regio...

BACKGROUND Vancomycin-resistant enterococci colonization has been reported to increase the risk of developing infections, including bloodstream infections. AIM In this study, we aimed to share our experience with the vancomycin-resistant enterococci bloodstream infections following gastrointestinal vancomycin-resistant enterococci colonization in pediatric population during a period of 18 mon...

Increased prevalence of Vancomycin-resistant Enterococci and their ability to transfer Vancomycin resistance genes to other bacteria have made them a subject of close scrutiny and intense investigation. This study was performed to determine the prevalence of Vancomycin-resistant Enterococci occurrence in children hospitalized in a Hospital in Tehran, Iran. During 12 months, we collected 780 sto...

BACKGROUND Vancomycin resistant enterococci are a frequent cause of nosocomial infections and their presence among farm animals is unwanted. Using media supplemented with vancomycin an increase in the proportion of samples from Swedish broilers positive for vancomycin resistant enterococci has been detected. The situation at farm level is largely unknown. The aims of this study were to obtain b...

Enterococci are used to assess the risk of negative human health impacts from recreational waters. Studies have shown sustained populations of enterococci within sediments of beaches but comprehensive surveys of multiple tidal zones on beaches in a regional area and their relationship to beach management decisions are limited. We sampled three tidal zones on eight South Florida beaches in Miami...

AIMS Isolate and characterize water enterococci from the South Nation River drainage basin, an area dominated by agriculture. METHODS AND RESULTS A total of 1558 enterococci were isolated from 204 water samples from the South Nation River obtained over a 3-year period. PCR was used to identify isolates to the species level and characterize them for carriage of 12 virulence determinants. Antib...

Culturable enterococci and a suite of environmental variables were collected during a predominantly dry summer at a beach impacted by nonpoint source pollution. These data were used to evaluate sands as a source of enterococci to nearshore waters, and to assess the relationship between environmental factors and dry-weather enterococci abundance. Best-fit multiple linear regressions used environ...
