What is Enterococcus faecium?
E. faecium is a human pathogen that causes nosocomial bacteremia, surgical wound infection, endocarditis, and urinary tract infections. Nosocomial infections are those acquired in medical setting during treatment of a prior complaint. E. faecium is a Gram-positive, spherical cell that can occur in pairs or chains.
What is the genome of Enterococcus faecalis?
E. faecalis is a close relative of E. faecium and its genome has been sequenced and analyzed. The sequencing of a vacomycin resistant E. faecalis strain, Enterococcus facalis V583, revealed 1 circular chromosome and 3 plasmids.
What is the phylum and class of Enterococcus?
Domain: Bacteria; Phylum Firmicutes; Class: Bacilli; Order: Lactobacillales; Family: Enterococcus (1) E. faecium is a human pathogen that causes nosocomial bacteremia, surgical wound infection, endocarditis, and urinary tract infections.
Is Enterococcus faecium resistant to vancomycin?
Resistance to vancomycin has been observed in both Enterococcus faecium and Enterococcus faecalis. Many patients have succumbed to bacteremia or other invasive infections with vancomycin-resistant enterococci (VRE).
Enterococcus faecium : 1 Enterococcus: Two species are common commensal organisms in the intestines of humans: E. 2 Gram-positive cocci that often occur in pairs (diplococci) or short chains. 3 Gram-positive, alpha hemolytic or nonhemolytic bacterium.
Is Enterococcus Gram positive or negative?
Gram-positive cocci that often occur in pairs (diplococci) or short chains. Gram-positive, alpha hemolytic or nonhemolytic bacterium. Important clinical infections caused by Enterococcus include urinary tract infections, bacteremia, bacterial endocarditis, diverticulitis, and meningitis.
What is the pathogen E coli faecium?
E. faecium is a human pathogen that causes nosocomial bacteremia, surgical wound infection, endocarditis, and urinary tract infections. Nosocomial infections are those acquired in medical setting during treatment of a prior complaint.
Enterococcus faecium is a Gram-positive, gamma-hemolytic or non- hemolytic bacterium in the genus Enterococcus. It can be commensal (innocuous, coexisting organism) in the gastrointestinal tract of humans and animals, but it may also be pathogenic, causing diseases such as neonatal meningitis or endocarditis .
What is the clinical importance of Enterococcus?
The clinical importance of the genus Enterococcusis directly related to its antibiotic resistance, which contributes to the risk of colonization and infection. The species of the greatest clinical importance are Enterococcus faecalisand Enterococcus faecium.
How do antibiotics affect the spread of Enterococcus faecium?
Spread of the disease occurs between patients in hospitals due to transfer of the pathogen by hands or medical instruments. Also antibiotic use can decrease the number of other intestinal bacteria that are susceptible to the antibiotic and decrease competition for the drug resistant E. faecium.
