Staphylococcus epidermidis is a Gram-positive bacterium, and one of over 40 species belonging to the genus Staphylococcus. [1] It is part of the normal human microbiota , typically the skin microbiota , and less commonly the mucosal microbiota and also found in marine sponges.
S. epidermidis, a coagulase-negative staphylococcus species, is a commensal of the skin, but can cause severe infections in immune-suppressed patients and those with central venous catheters. S. saprophyticus , another coagulase -negative species that is part of the normal vaginal flora , is predominantly implicated in uncomplicated lower ...
Current treatment includes topical and systemic antibacterial drugs which result in decreased C. acnes colonisation and/or activity. [41] Potential probiotic treatment includes the use of Staphylococcus epidermidis to inhibit C. acnes growth. S. epidermidis produces succinic acid which has been shown to inhibit C. acnes growth. [42]
It is identitified as a species of coagulase-negative staphylococci (CoNS) using the coagulase test. Lastly, S. saprophyticus is differentiated from S. epidermidis, another species of pathogenic CoNS, by testing for susceptibility to the antibiotic novobiocin. S. saprophyticus is novobiocin-resistant, whereas S. epidermidis is novobiocin ...
Staphylococcus species can be differentiated from other aerobic and facultative anaerobic, Gram-positive cocci by several simple tests. [15] Staphylococcus species are facultative anaerobes (capable of growth both aerobically and anaerobically). [15] All species grow in the presence of bile salts.
Staphylococcus haemolyticus is a member of the coagulase-negative staphylococci (CoNS). [2] It is part of the skin flora of humans, [ 3 ] and its largest populations are usually found at the axillae , perineum , and inguinal areas. [ 4 ]
Novobiocin, also known as albamycin, is an aminocoumarin antibiotic that is produced by the actinomycete Streptomyces niveus, which has recently been identified as a subjective synonym for S. spheroides [1] a member of the class Actinomycetia. Other aminocoumarin antibiotics include clorobiocin and coumermycin A1. [2]
Staphylococcus capitis is a coagulase-negative species (CoNS) of Staphylococcus. It is part of the normal flora of the skin of the human scalp, face, neck, scrotum, and ears and has been associated with prosthetic valve endocarditis, but is rarely associated with native valve infection.
