Moreover, a variant of the esp gene, which has been found to be more prevalent among isolates of E. faecalis associated with infections ( 14 ), was found in all but one epidemic hospital-derived VREF isolate and not among community-derived VREF ( 12 ). (cdc.gov)
Important clinical infections caused by Enterococcus include urinary tract infections (see Enterococcus faecalis), bacteremia, bacterial endocarditis, diverticulitis, meningitis, and spontaneous bacterial peritonitis. (wikipedia.org)
Enterococcus faecalis and faecium are two major representative clinical strains of the Enterococcus genus and are sadly notorious to be part of the top agents responsible for nosocomial infections. (frontiersin.org)
Here, using the dRNA-seq technique in combination with ANNOgesic analysis, we successfully mapped and annotated transcription start sites (TSS) of both E. faecalis V583 and E. faecium AUS0004 at single nucleotide resolution. (frontiersin.org)
Analyzing bacteria in late exponential phase, we capture ~40% ( E. faecalis ) and 43% ( E. faecium ) of the annotated protein-coding genes, determine 5′ and 3′ UTR (untranslated region) length, and detect instances of leaderless mRNAs. (frontiersin.org)
In particular, Enterococcus faecalis KB1 was identified as an important driver of community composition by affecting the abundance of several other consortium members in vitro. (nature.com)
A high frequency of E. faecalis was found in teeth with inadequate endodontic treatment or dental crown restorations. (bvsalud.org)
Enterococcus faecalis is a commensal organism, part of the normal microbiota of the digestive system, but it can also be an opportunistic human pathogen. (bvsalud.org)
Sixty-five microorganisms were isolated, among which 56.9% were coagulase-negative Staphylococcus, 26.2% were Gram-negative bacilli, 7.7% were Enterococcus faecalis, and 6.2% were Candida parapsilosis. (bvsalud.org)
Enterococci are able to form biofilm in the prostate gland, making their eradication difficult. (wikipedia.org)
Strains5
In the last two decades, particularly virulent strains of Enterococcus that are resistant to vancomycin (vancomycin-resistant Enterococcus, or VRE) have emerged in nosocomial infections of hospitalized patients, especially in the US. (wikipedia.org)
In this study, the biofilm formation potential of L. monocytogenes strains isolated from the mushroom production environment was investigated on materials and at temperatures relevant to mushroom production. (ucc.ie)
The biofilm formation of a subset (n = 7) of these strains was then assessed on twelve different materials, including materials that are representative of the materials commonly found in the mushroom production environments, using the CDC biofilm reactor. (ucc.ie)
All the strains tested using the CDC biofilm reactor were able to form biofilms on the different surfaces tested but material type was found to be a key determining factor on the levels of biofilm formed. (ucc.ie)
Stainless steel, aluminium, rubber, polypropylene and polycarbonate were all able to support biofilm levels in the range of 4-4.9 log10 CFU/cm2, for seven different L. monocytogenes strains. (ucc.ie)

Genus2
Enterococcus is a large genus of lactic acid bacteria of the phylum Bacillota. (wikipedia.org)
citation needed] Members of the genus Enterococcus (from Greek έντερο, éntero, "intestine" and κοκκος, coccos, "granule") were classified as group D Streptococcus until 1984, when genomic DNA analysis indicated a separate genus classification would be appropriate. (wikipedia.org)
Isolates5
Clusters of VSEF fit well into previously described VREF genogroups, and strong associations were found between VSEF and VREF isolates with resistance to ampicillin, presence of esp , and purK 1. (cdc.gov)
A recently developed multilocus sequence typing scheme for E. faecium confirmed that epidemic isolates belonged to a specific genetic lineage ( 13 ). (cdc.gov)
Subsequently, other investigators described the variant esp gene in vancomycin-susceptible E. faecium (VSEF), and this gene appeared to be predominantly present among clinical isolates ( 15 - 18 ).These findings suggest the existence of a specific subpopulation of E. faecium , comprising both VREF as well as VSEF, associated with hospital outbreaks and infections. (cdc.gov)
Generally avoid synergistic combinations except for those pathogens for which such therapy is clearly indicated, such as enterococci, S viridans , HACEK isolates, and infections of intracardiac devices. (medscape.com)
A preliminary assessment of biofilm formation of 73 mushroom industry isolates was undertaken using a crystal violet assay on polystyrene microtitre plates. (ucc.ie)

Vancomycin6
The epidemiology of vancomycin-resistant Enterococcus faecium (VREF) in Europe is characterized by a large community reservoir. (cdc.gov)
We investigated the genetic relatedness of vanA VREF (n=108) and vancomycin-susceptible E. faecium (VSEF) (n=92) from different epidemiologic sources by genotyping, susceptibility testing for ampicillin, sequencing of purK 1, and testing for presence of esp . (cdc.gov)
evidence exists for nosocomial selection of a subtype of E. faecium , which has acquired vancomycin-resistance through horizontal transfer. (cdc.gov)
In the United States, the emergence of nosocomial E. faecium infections was characterized by increasing resistance to ampicillin in the 1980s and a rapid increase of vancomycin resistance in the next decade ( 1 , 2 ). (cdc.gov)
The emergence of vancomycin-resistant E. faecium (VREF) in the United States illustrates the transmission capacities of bacteria and the possibility of a postantibiotic era for nosocomial infections in critically ill patients. (cdc.gov)
Gentamicin may need to be added because a growing degree of tolerance of staphylococci and enterococci to vancomycin may induce partial resistance of bacteria to daptomycin and other antibiotics by inducing cellular wall thickening. (medscape.com)
