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 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.
A Gram stain of mixed Staphylococcus aureus (S. aureus ATCC 25923, gram-positive cocci, in purple) and Escherichia coli (E. coli ATCC 11775, gram-negative bacilli, in red), the most common Gram stain reference bacteria. Gram stain (Gram staining or Gram's method), is a method of staining used to classify bacterial species into two large groups ...
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 casseliflavus is a species of commensal Gram-positive bacteria. Its name derived from the "flavus" the Latin word for yellow due to the bright yellow pigment that it produces. [ 2 ] This organism can be found in the gastrointestinal tract of humans [ 3 ]
The genus Enterococcus belongs to the family Enterococcaceae. This genus is divided into 58 species and two subspecies. [18] These gram-positive, coccoid bacteria were once thought to be harmless to the human body. However, within the last ten years, there has been an influx of nosocomial pathogens originating from Enterococcus bacteria. [19] [11]
Bile Esculin Agar (BEA) is a selective differential agar used to isolate and identify members of the genus Enterococcus, [1] formerly part of the "group D streptococci" (enterococci were reclassified in their own genus in 1984). [2]
Bacteria of the genus Enterococcus, formerly known as group D streptococci, were classified as members of the genus Streptococcus until 1984 and are included in the original Lancefield grouping. [4] Many—but not all—species of streptococcus are beta-hemolytic .
