Surveillance for Vancomycin Resistant Enterococci in a Tertiary Institution in South Western Nigeria
BACKGROUND Enterococci are responsible for up to 12% of cases of healthcare associated infections worldwide and cause life threatening infections among critically ill patients. They show intrinsic and acquired resistance to a wide range of antimicrobial agents. Glycopeptide resistance is due to vanA, vanB, vanC, vanD, vanE, vanG and vanL genes. OBJECTIVES To determine the carriage rate of VRE...
background vancomycin-resistant enterococci (vre) are the most common nosocomial pathogen worldwide. colonization with vre can lead to serious infection, some of which e.g. vre sepsis can be fatal. because vre are dangerous important pathogens, we aimed to determine the prevalence of vre among patients admitted in infectious, icu and surgery wards in a referral teaching hospital in isfahan, ira...
V ancomycin-resistant enterococci (VRE) were first reported from Europe in the late 1980s (1). The proposed origin of VRE was nosocomial, but these bacteria have also been isolated from several animal sources. The growth promoter avoparcin in animal husbandry has probably played a role in the development of resistance (2). The rapid dissemination of VRE among humans has urged clinical microbiol...
BACKGROUND & OBJECTIVES Enterococci, classified as group D streptococci, are the second leading cause of nosocomial infections. The incidence of enterococcal infections and species prevalent in India is not thoroughly investigated. The present study was undertaken to isolate and characterize enterococci from clinical specimens and determine the antimicrobial susceptibility pattern of these isol...
We developed a methodology for antimicrobial susceptibility testing (AST) based on the BacterioScanTM216R laser scattering technology, using methicillin resistance in Staphylococcus aureus and vancomycin resistance in enterococci as exemplar for important resistance phenotypes. Fifty methicillin-resistant (MRSA) and 50 methicillin-susceptible (MSSA) S. aureus, as well as 50 vancomycin-resistant...
Recent data indicates an increasing rate of vancomycin resistance in clinical enterococcal isolates worldwide. The nosocomial enterococci are likely to harbor virulence elements that increase their ability to colonize hospitalized patients. The aim of this study was to characterize virulence determinants in vancomycin-resistant enterococci (VRE) obtained from various clinical sources.During the...
Background This study aimed to investigate the incidence of antibiotic-resistance and virulence genes in vancomycin-resistant Enterococcus faecium isolated from different sources in southwest Iran from Mar to Sep 2015. Methods Overall, 120 E. faecium isolates (80 VRE and 40 vancomycin-susceptible enterococci [VSE] isolates) were obtained from four hospitals. The resistance of the VRE isolates...
Enterococci with resistance to glycopeptides have recently emerged in Australia. We developed multiplex PCR assays for vanA, vanB, vanC1, and vanC2 or vanC3 in order to examine the genetic basis for vancomycin resistance in Australian isolates of vancomycin-resistant Enterococcus faecium and E. faecalis (VRE). The predominant genotype from human clinical E. faecium isolates was vanB. The PCR va...
Vancomycin and teicoplanin are still the only glycopeptide antibiotics availAbstract able for use in humans. Emergence of resistance in enterococci and staphylococci has led to restriction of their use to severe infections caused by Gram-positive bacteria for which no other alternative is acceptable (because of resistance or allergy). In parallel, considerable efforts have been made to produce ...
Between July 1, 2002 and December 31, 2003, rectal swabs from both hospitalized patients and community subjects in the Czech Republic were taken to ascertain the prevalence of vancomycin-resistant enterococci (VRE). The swabs were used for isolating and identifying enterococci and their susceptibility to antibiotics. Vancomycin resistance phenotypes were verified by PCR detection of vanA, vanB,...
