  2. Coagulase - Wikipedia

    en.wikipedia.org/wiki/Coagulase

    A negative coagulase test would instead show the presence of coagulase-negative organisms such as S. epidermidis or S. saprophyticus. However, it is now known that not all S. aureus are coagulase-positive. [2] [3] Whereas coagulase-positive staphylococci are usually pathogenic, coagulase-negative staphylococci are more often associated with ...

  3. Staphylococcal infection - Wikipedia

    en.wikipedia.org/wiki/Staphylococcal_infection

    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 ...

  4. Staphylococcus - Wikipedia

    en.wikipedia.org/wiki/Staphylococcus

    Staphylococcus species are facultative anaerobes (capable of growth both aerobically and anaerobically). [15] All species grow in the presence of bile salts. All strains of Staphylococcus aureus were once thought to be coagulase-positive, but this has since been disproven. [16] [17] [18] Growth can also occur in a 6.5% NaCl solution. [15]

  5. Staphylococcus aureus - Wikipedia

    en.wikipedia.org/wiki/Staphylococcus_aureus

    Staphylococcus aureus is a significant cause of chronic biofilm infections on medical implants, and the repressor of toxins is part of the infection pathway. [30] Staphylococcus aureus can lie dormant in the body for years undetected. Once symptoms begin to show, the host is contagious for another two weeks, and the overall illness lasts a few ...

  6. Staphylococcus capitis - Wikipedia

    en.wikipedia.org/wiki/Staphylococcus_capitis

    Some staphylococci are capable of producing free coagulase. Thus, that is used to differentiate Staphylococcus species. In this context, a distinction is made in species between coagulase-positive and coagulase-negative staphylococci. Staphylococcus capitis is a species in the genus that is positive for staph coagulase. [6]

  7. Staphylococcus epidermidis - Wikipedia

    en.wikipedia.org/wiki/Staphylococcus_epidermidis

    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.

  8. Staphylococcus hominis - Wikipedia

    en.wikipedia.org/wiki/Staphylococcus_hominis

    Staphylococcus hominis is a coagulase-negative member of the bacterial genus Staphylococcus, consisting of Gram-positive, spherical cells in clusters.It occurs very commonly as a harmless commensal on human and animal skin and is known for producing thioalcohol compounds that contribute to body odour.

  9. Staphylococcus schleiferi - Wikipedia

    en.wikipedia.org/wiki/Staphylococcus_schleiferi

    Staphylococcus schleiferi is a Gram-positive, cocci-shaped bacterium of the family Staphylococcaceae. [1] It is facultatively anaerobic, coagulase-variable, and can be readily cultured on blood agar where the bacterium tends to form opaque, non-pigmented colonies and beta (β) hemolysis. [2]
