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 ...
Previously such identification had depended upon microbiological culture upon which many varieties of bacteria did not grow and so were hidden to science. [1] Staphylococcus epidermidis and Staphylococcus aureus were thought from cultural based research to be dominant. However 16S ribosomal RNA research finds that while common, these species ...
The species and diversity of the microorganisms may be related to the various levels of hormones during pregnancy. Vaginal flora can be transmitted to babies during birth. Vaginal dysbiosis can lead to vaginal infections like bacterial vaginosis which makes one relatively susceptible to sexually transmitted diseases.
S. epidermidis, a coagulase-negative species, is a commensal of the skin, but can cause severe infections in immunosuppressed 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 genitourinary tract infections in sexually ...
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 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 ]
In the laboratory, it is used to distinguish between different types of Staphylococcus isolates. Importantly, S. aureus is generally coagulase-positive, meaning that a positive coagulase test would indicate the presence of S. aureus or any of the other 11 coagulase-positive Staphylococci. [1]
