Local genetic patterns within a vancomycin-resistant Enterococcus faecalis clone isolated in three hospitals in Portugal.

چکیده
Eight pulsed-field gel electrophoresis subtypes and six Tn1546 variants were identified among Enterococcus faecalis isolates of a single clone recovered in three geographically separate Portuguese hospitals. Some clonal subtypes were found in particular hospitals, and Tn1546 variants were either widespread or confined to some of them. We also report on the first Tn1546 transposon containing an ISEf1 insertion.

Clonal expansion within clonal complex 2 and spread of vancomycin-resistant plasmids among different genetic lineages of Enterococcus faecalis from Portugal.
OBJECTIVES The aim of this study was to assess the diversity of Enterococcus faecalis populations recovered in different regions of Portugal during the last decade (1996-2007) and to analyse their genetic elements associated with vancomycin resistance. METHODS Forty E. faecalis isolates (22 vancomycin-susceptible and 18 vancomycin-resistant) representing disseminated and/or multiresistant str...
متن کاملMolecular Identification of Pathogenic Enterococci and Evaluation of Multi-drug Resistance in Enterococcus Species Isolated From Clinical samples of Some Hospitals in Tehran, Iran
Background: Multidrug-resistant (MDR) enterococci cause many problems for physicians and infection control specialists in the recent years. Hence, by the identification of antibiotic resistance patterns of enterococci in different geographical regions an appropriate strategy can be developed to prevent bacterial antibiotic resistance and provide effective treatment. The current study aimed at i...

Abstract Background and Objective: some of predisposing factors for enterococci colonization are hospitalization in ICU, prolonged use of antibiotics and continued bed rest in hospital. In this study antibiotic resistance of enterococcus in hospitalized patients of four hospitals in Tehran were studied. Material and Methods: the Clinical samples were taken from patients admitted to the ICU, fro...
متن کاملVancomycin-resistant enterococci among haemodialysis patients in Portugal: prevalence and molecular characterization of resistance, virulence and clonality.
INTRODUCTION Vancomycin-resistant enterococci (VRE) among haemodialysis patients has increased rapidly and, to date, there is no report of this incidence in Portugal. METHODS A total of 121 faecal samples were collected from haemodialysis patients, and then tested for VRE. Antimicrobial resistance, virulence and multilocus sequence typing (MLST) were studied. RESULTS VRE prevalence was 3.3%...

Geographic spread of vancomycin-resistant enterococci (VRE) clones in cities, countries, or even continents has been identified by molecular techniques. This study aimed at characterizing virulent genes and determining genetic relatedness of 45 VRE isolates from Trinidad and Tobago using molecular tools, including polymerase chain reaction, pulsed-field gel electrophoresis (PFGE), and Random Am...
