Enterococcus is a large genus of lactic acid bacteria of the phylum Bacillota. Enterococci are Gram-positive cocci that often occur in pairs ( diplococci ) or short chains, and are difficult to distinguish from streptococci on physical characteristics alone. [ 2 ]
Enterococcus faecium is a Gram-positive, gamma-hemolytic or non-hemolytic bacterium in the genus Enterococcus. [1] It can be commensal (innocuous, coexisting organism) in the gastrointestinal tract of humans and animals, [ 2 ] but it may also be pathogenic , causing diseases such as neonatal meningitis or endocarditis .
Enterococcus faecalis – formerly classified as part of the group D Streptococcus system – is a Gram-positive, commensal bacterium inhabiting the gastrointestinal tracts of humans. [ 1 ] [ 2 ] Like other species in the genus Enterococcus , E. faecalis is found in healthy humans and can be used as a probiotic.
The antibiotic, rifaximin, has enabled the global emergence of vancomycin-resistant enterococcus faecium, or VRE, a superbug that frequently causes serious infections in hospitalised patients ...
ESKAPE is an acronym comprising the scientific names of six highly virulent and antibiotic resistant bacterial pathogens including: Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter spp. [1] The acronym is sometimes extended to ESKAPEE to include Escherichia coli. [2]
Enterococcus raffinosus has been identified as a pathogen in Homo sapiens and Felis catus with vancomycin-resistant strains (VRE) involved in hospital-acquired infections that cause Crohn's disease. [3] [4] Additionally, this species uses Camelus dromedarius and Helix pomatia as hosts. [5]
E. gallinarum was found during three liver biopsies of individuals with systemic lupus erythematosus and autoimmune liver disease. The autoimmune reaction was found to be suppressed when an intramuscular vaccine or antibiotic was administered. [8] [9] The bacterium can also cause meningitis, although rare [10] and sepsis. [11]
Cases of norovirus — the virulent, wildly contagious virus that causes vomiting and diarrhea — are increasing in the U.S., the Centers for Disease Control says, reporting double the amount of ...
