Emergence of vancomycin-resistant Enterococci (VRE) that first appeared on the stage about three decades ago is now a major concern worldwide as it has globally reached every continent. Our aim was to simply undertake a multinational study to delineate the resistance and virulence genes of clinical isolates of VRE isolates from the Caribbean. We employed both conventional (standard microbiologi...

Although normally regarded harmless commensals, enterococci may cause a range of different infections in humans, including urinary tract infections, sepsis, and endocarditis. The acquisition of vancomycin resistance by enterococci (VRE) has seriously affected the treatment and infection control of these organisms. VRE are frequently resistant to all antibiotics that are effective treatment for ...

Vancomycin-resistant enterococci (VRE) are important hospital pathogens and have become increasingly common in patients admitted to the intensive care unit (ICU). To determine the incidence and the risk factors associated with VRE colonisation among ICU patients, active surveillance cultures for VRE faecal carriages were carried out in patients admitted to the ICU of the University Hospital of ...

Enterococci for which the minimum inhibitory concentration (MIC) of vancomycin was >/=8 mg/l were isolated from meat, feces, and raw milk samples collected in Korea from March to November 2003. Among the 243 vancomycin-resistant enterococci (VRE) that were identified the vanA vancomycin resistance gene was carried by 51 Enterococcus faecium and one Enterococcus sp., vanC1 was carried by 151 Ent...

UNLABELLED Treatment of multidrug-resistant enterococci has become a challenging clinical problem in hospitals around the world due to the lack of reliable therapeutic options. Daptomycin (DAP), a cell membrane-targeting cationic antimicrobial lipopeptide, is the only antibiotic with in vitro bactericidal activity against vancomycin-resistant enterococci (VRE). However, the clinical use of DAP ...

BACKGROUND Enterococci are the most important multidrug resistant organisms associated with immunocompromised patients. Data are lacking about the epidemiology of vancomycin resistant Enterococci (VRE) in Ethiopia. This study aimed to assess the prevalence of VRE, their susceptibility patterns to different antibiotics and associated risk factors in fecal samples of Human Immunodeficiency Virus ...

BACKGROUND & OBJECTIVES There is a paucity of information on vancomycin resistance in enterococci from India. In the present study, enterococci isolated from urine specimen were screened for vancomycin resistance. METHODS 144 enterococci isolates obtained in pure and significant numbers (>10(5) cfu/ml) from 9664 urine specimens were subjected to agar screen method of National Committee for Cl...

Eighty clinical microbiology laboratories in Taiwan were evaluated for proficiency in the determination of vancomycin susceptibility of enterococci. Each laboratory was given 1 vancomycin-sensitive isolate and 3 vancomycin-resistant enterococci (VRE) isolates to determine the levels of vancomycin resistance. Among a total of 240 tests performed, 153 (63.8%) correctly determined the levels of va...

To assess the potential for emergence of resistance during the use of linezolid, we tested 10 clinical isolates of vancomycin-resistant enterococci (VRE) (four Enterococcus faecalis, five Enterococcus faecium, and one Enterococcus gallinarum) as well as a vancomycin-susceptible control (ATCC 29212) strain of E. faecalis. The enterococci were exposed to doubling dilutions of linezolid for 12 pas...

Vancomycin-resistant enterococci (VRE) are important pathogens causing nosocomial infections, and there is reason for concern about their resistance and great ability to spread in hospital environments, especially intensive-care units (ICU). To determine the prevalence of rectal colonization by VRE, and the risk factors associated with their presence, rectal surveillance swabs were taken from p...
