enterococci, as the major cause of nosocomial infections, have been shown to have an increase in drug resistance during the past two decades. theentrococcalemergence of vancomycin-resistant is very important nowadays. the purpose of this study was to determine the drug sensitivity of enterococcus faecalis and enterococcus faecium species against vancomycin, tetracycline, gentamicin, erythromyci...

The genes encoding the VanA type of vancomycin resistance in enterococci are located on elements related to Tn1546 (1). Heterogeneity of Tn1546 in Enterococcus faecium has been previously reported (3, 4, 6, 9, 10, 12, 14, 15, 16) and includes deletions, insertions, and mutations. In this study, Tn1546 elements from 43 vanA-containing isolates of different enterococcal species with diverse pulse...

background: vancomycin (glycopeptide)-resistant enterococci (vre or gre) can cause serious problems for hospitalized patients due to the limited options for treatment of vre infections. as infection with vre increases in hospitals, further knowledge about vancomycin resistant genes is needed. methods: isolates of enterococcus spp. were collected from hospitalized patients in tehran (iran) durin...

Background. Oritavancin (ORI) is under regulatory review in the USA and Europe for the treatment of acute bacterial skin and skin structure infections (SSSI) caused by Gram-positive pathogens. The ORI activity was assessed against contemporary isolates causing SSSI. Methods. 8,428 isolates from documented SSSI were collected from 27 sites in the USA and 34 sites in Europe, Israel and Turkey as ...

In this study we report the first isolation of VanA-type vancomycin-resistant Enterococcus faecalis strains from two different patients hospitalized in the same intensive care unit at the hospital of Universidade Federal do Triângulo Mineiro (UFTM), Uberaba, Minas Gerais, Brazil.
