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.
In clinical medicine, antibiotics are most frequently prescribed on the basis of a person's symptoms and medical guidelines.This method of antibiotic selection is called empiric therapy, [1] and it is based on knowledge about what bacteria cause an infection, and to what antibiotics bacteria may be sensitive or resistant. [1]
However, it has retained some clinical usefulness even after the taxonomic changes, [1] and as of 2018, Lancefield designations are still often used to communicate medical microbiological test results. The classification assigns a letter code to each serotype. There are 20 described serotypes assigned the letters A to V (excluding E, I and J). [3]
This phenomenon is the mechanism behind the CAMP test, [2] a test that was historically used for the identification of Streptococcus agalactiae and Listeria monocytogenes. [3] A modified version of this test called the reverse CAMP test, utilizing S. agalactiae instead of S. aureus , can also be used to identify Clostridium perfringens .
Gram-positive bacteria retain the crystal violet stain used in the test, resulting in a purple color when observed through an optical microscope. The thick layer of peptidoglycan in the bacterial cell wall retains the stain after it has been fixed in place by iodine. During the decolorization step, the decolorizer removes crystal violet from ...

Vancomycin. Six different types of vancomycin resistance are shown by enterococcus: Van-A, Van-B, Van-C, Van-D, Van-E and Van-G. [4] The significance is that Van-A VRE is resistant to both vancomycin and teicoplanin, [5] Van-B VRE is resistant to vancomycin but susceptible to teicoplanin, [6] [7] and Van-C is only partly resistant to vancomycin.
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.
