conclusions: the combination of plasmid profiling and php techniques revealed the presence of diverse population of vre in sewage treatment plant in tehran. furthermore, the results showed that the php technique is a reliable method in determining the vre clonal diversity. results: all isolates were found to be resistant to erythromycin, ampicillin and ciprofloxacin. the pcr analyses showed tha...

In this study, thermal processes were developed for cocoa powder against Salmonella and Listeria monocytogenes in a pilot Radiofrequency (RF) unit validated using their respective surrogates Enterococcus faecium NRRL B-2354 innocua. For 1.0 kg samples, RF heating to 90 °C provided 1.74–1.84 log reduction of E. faecium. A 48 min holding post-RF an additional 3.65 2.24 log10 CFU/g insulated non-i...

In recent years, vancomycin-resistant enterococci, especially Enterococcus faecium has emerged as an important nososcomial pathogen and represents a serious threat to patients with impaired host defences. We report infection with vancomycin-resistant Enterococcus faecium in a 3-year-old child with patent ductus arteriosus. The organism, isolated from a central venous catheter tip, exhibited a h...

From 125 separate cloacal cultures from three turkey flocks fed virginiamycin, 104 Enterococcus faecium and 186 Enterococcus faecalis isolates were obtained. As the turkeys aged, there was a higher percentage of quinupristin-dalfopristin-resistant E. faecium isolates, with isolates from the oldest flock being 100% resistant. There were no vancomycin-resistant enterococci. Results of pulsed-fiel...

background: enterococci have emerged as a major cause of nosocomial infections and within this group, enterococcus faecalis and enterococcus faecium cause the majority of human and livestock enterococcal infections. in this article, we tried to determine antibiotics and metals resistance patterns of e. faecalis and e. faecium strains. methods: one hundred sixty different strains of e. faecalis ...

The microbiome of the uterus cows with acute postpartum purulent-catarrhal endometritis is represented by Streptococcus faecium, Citrobacter freundii, Escherichia coli, Staphylococcus aureus, pyogenes, Proteus vulgaris. Conditionally pathogenic microflora was predominant. Of all tested praparations (Geomytsin, Enroflon, Mitrek), highest zone growth inhibition to most isolated isolates noted in ...

The E test and the reference agar dilution methods were compared for detecting high-level aminoglycoside resistance (HLAR) among 71 selected clinical isolates, including 62 Enterococcus faecalis and 9 Enterococcus faecium isolates. High-level gentamicin resistance alone was found in 11% (5 E. faecalis and 3 E. faecium strains) and high-level streptomycin resistance was found in 42% (28 E. faeca...

BACKGROUND The aim of this study was to determine the occurrence of virulence determinants and vancomycin-resistant genes among Enterococcus faecalis and E. faecium obtained from various clinical sources. METHODS The study was performed on the 280 enterococcal isolated from clinical specimens in Hamadan hospitals, western Iran in 2012-14. Antibiotic susceptibility testing was performed using ...

Ten isolates of Streptococcus faecalis and two isolates of S. faecium were studied together with an NCTC strain of each species. Antibiotic susceptibility tests showed different patterns of high-level resistance to aminoglycosides. Three S. faecalis strains were highly resistant to gentamicin and other aminoglycosides. By means of a filter membrane technique, transfer of high-level resistance t...

OBJECTIVES Linezolid is an oxazolidinone antibiotic used in the treatment of infections caused by vancomycin-resistant enterococci. Resistance to linezolid has been associated with a G2576U mutation in domain V of the 23S rRNA. PATIENT AND METHODS We present clinical details and susceptibility data from multiple Enterococcus faecium strains isolated from a liver transplant patient over 13 mon...
