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. [2] [3] It is a facultative anaerobic bacteria.
Staphylococcus and Corynebacterium were among the most common types of bacteria found in the navels of this project's volunteers and these types of bacteria have been found to be the most common types of bacteria found on the human skin in larger studies of the skin microbiome [18] (of which the Belly Button Biodiversity Project is a part). [10]
Staphylococcus was one of the leading infections in hospitals and many strains of this bacterium have become antibiotic resistant. Despite strong attempts to get rid of them, staphylococcus bacteria stay present in hospitals, where they can infect people who are most at risk of infection. [4] Staphylococcus includes at least 44 species.
PSMs were first discovered in S. epidermidis by Seymour Klebanoff via hot-phenol extraction and were described as a pro-inflammatory complex of three peptides. [2] Since their initial discovery, numerous roles of PSMs have been identified. However, due in part to the small size of many PSMs, they have largely gone unnoticed until recent years.
The first discovered enzyme of this family, and the most well characterized, was isolated from the Staphylococcus aureus strain V8, and hence better known as "V8 protease". Other common references to this protease are staphylococcal serine protease, and SspA from its corresponding gene. [1] [2] [3] S. epidermidis glutamyl endopeptidase GluSE [1 ...
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 ...
A type of bacteria that causes dental plaque may be behind a treatment-resistant form of colorectal cancer, a study published Wednesday in the journal Nature found.. The particular bacterium ...
Staphylococcus aureus is a gram-positive spherically shaped bacterium, a member of the Bacillota, and is a usual member of the microbiota of the body, frequently found in the upper respiratory tract and on the skin. It is often positive for catalase and nitrate reduction and is a facultative anaerobe, meaning that it can grow without oxygen. [1]
