In humans, S. saprophyticus is found in the normal flora of the female genital tract [3] and perineum. [4] It has been isolated from other sources, too, including meat and cheese products, vegetables, the environment, and human and animal gastrointestinal tracts. [4] S. saprophyticus causes 10–20% of urinary tract infections (UTIs).
The S. saprophyticus and S. sciuri groups are generally novobiocin-resistant, as is S. hominis subsp. novobiosepticus. Members of the S. sciuri group are oxidase-positive due to their possession of the enzyme cytochrome c oxidase. This group is the only clade within the staphylococci to possess this gene.

S. saprophyticus, another coagulase-negative species that is part of the normal vaginal flora, is predominantly implicated in uncomplicated lower genitourinary tract infections in young sexually active women. [9] Other staphylococcal species have been implicated in human infections, notably S. lugdunensis, S. schleiferi, and S. caprae.
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] A negative coagulase test would instead show the presence of coagulase-negative organisms such as S. epidermidis or S. saprophyticus.

Staphylococcus capitis is a coagulase-negative species (CoNS) of Staphylococcus.It is part of the normal flora of the skin of the human scalp, face, neck, scrotum, and ears and has been associated with prosthetic valve endocarditis, but is rarely associated with native valve infection.
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.
