background enterococci are a natural part of the genito-intestinal and gastrointestinal normal flora in humans and are widely distributed in the environment and are one of the most important causes of nosocomial infections. conclusions in this study none of the isolates were resistant to vancomycin, while 20% of isolates with mic of 4 μg ml-1 had intermediate reaction to it. other demographic p...

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...

This review deals with the duality of enterococci, which can be illustrated by their yin yang behaviour. The rough nature of this specific group of lactic acid bacteria promotes their dissemination in various environments where they significantly influence the outcome of a certain process. In the technological meaning, enterococci are leading microbes in fermentation processes of traditional fo...

The genus Enterococcus is represented by some of the clinically important species and is well known for its antibiotic resistance, which participates in colonization and infection. Increasing resistance of enterococci has been evoked due to the excessive use of antibiotics not merely for therapeutic purposes or in indicated cases. One of the promising possibilities how to reduce the use of grea...

results disk diffusion agar showed that 96 strains (48%) were resistant to gentamicin, 89 (44.5%) to ciprofloxacin, 127 (63.5%) to erythromycin, 142 (71%) to tetracycline, 11 (5.5%) to teicoplanin, 32 (16%) to vancomycin, none to linezolid and 96 (48%) to co-trimoxazole. the mics of the resistant isolates were as follows; 88 strains had mic ≥ 32 μg/ml to vancomycin and 59 strains had mic ≥ 32 μ...

background and objectives: we developed and evaluated the utility of a quadruplex taqman real-time pcr assay that allows simultaneous identification of vancomycin-resistant genotypes and clinically relevant enterococci. materials and methods: the specificity of the assay was tested using reference strains of vancomycin-resistant and susceptible enterococci. in total, 193 clinical isolates were ...

Enterococci isolated from packaging areas of meat-processing facilities that produce ready-to-eat meat products were examined for high-level vancomycin resistance. A total of 406 enterococci isolates from the plants' packaging areas were examined for vancomycin resistance. High-level vancomycin resistance was not demonstrated in any enterococci isolated from 12 meat-processing plants.

enterococci are normal inhabitants of gastrointestinal tract, being responsible for 5 to 18% of infective endocarditis and the incidence appears to be increasing. eleven patients with enterococcal endocarditis were studied. in a case series group, 10 men (average 57 years) and one woman (37 years) were studied. two patients had rheumatic heart disease, 5 patients arteriosclerotic disease and on...

Elements mediating VanA glycopeptide resistance in 106 diverse enterococci from humans and nonhuman sources were compared with the prototype VanA transposon, Tn1546, in Enterococcus faecium BM4147. The isolates included 64 from individual patients at 15 hospitals in the United Kingdom (isolated between 1987 and 1996) and 42 from nonhuman sources in the United Kingdom (27 from raw meat, 7 from a...
