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 ...
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 generally harmless commensal on human and animal skin and is known for producing thioalcohol compounds that contribute to body odour .
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 ...
Staphylococcus xylosus is a species of bacteria belonging to the genus Staphylococcus. It is a Gram-positive bacterium that forms clusters of cells. Like most staphylococcal species, it is coagulase -negative and exists as a commensal on the skin of humans and animals and in the environment.
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]
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]
Staphylococcus warneri is a member of the bacterial genus Staphylococcus, consisting of Gram-positive bacteria with spherical cells appearing in clusters. It is catalase -positive, oxidase -negative, and coagulase -negative, and is a common commensal organism found as part of the skin flora on humans and animals.
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] S. haemolyticus also colonizes primates and domestic animals. [4]
