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 ...
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 ...
Antibiotic sensitivity testing is also conducted at a population level in some countries as a form of screening. [4] This is to assess the background rates of resistance to antibiotics (for example with methicillin-resistant Staphylococcus aureus), and may influence guidelines and public health measures. [4]
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.
A Cochrane review found that while it is an effective treatment for shigellosis it also produces more significant adverse effects than other antibiotic drugs. [43] Staphylococcus aureus infections: No: No: No: In vitro and in vivo activity against both non-resistant and methicillin-resistant Staphylococcus aureus (MRSA) infections. [44] [45 ...
The system, created by Rebecca Lancefield, was historically used to organize the various members of the family Streptococcaceae, which includes the genera Lactococcus and Streptococcus, but now is largely superfluous due to explosive growth in the number of streptococcal species identified since the 1970s.

SSSS is a clinical diagnosis. This is sometimes confirmed by isolation of S. aureus from blood, mucous membranes, or skin biopsy; however, these are often negative. Skin biopsy may show separation of the superficial layer of the epidermis (intraepidermal separation), differentiating SSSS from TEN, wherein the separation occurs at the dermo-epidermal junction (subepidermal separation).
