What causes Staphylococcus capitis?
It is most frequently caused by S. aureus (and sometimes by Staphylococcus lugdunensis and Staphylococcus capitis) followed by certain streptococci of the Streptococcus milleri group (Streptococcus constellatus, Streptococcus anginosus and Streptococcus intermedius) and enterococci.
How is Staphylococcus capitis treated?
It is generally assumed that S. capitis responds to nafcillin, cephalosporins, and vancomycin with or without rifampin. Cefalotin was the first-choice treatment, but as the patient suffered acute tubular necrosis the antibiotic was changed to daptomycin.
Is Staphylococcus capitis gram positive?
Staphylococcus capitis are Gram positive cocci belonging to the Coagulase-Negative Staphylococci group (CoNS) that is frequently found on the human skin and mucosa [1],[2] and even in the human gut [3]. Although infection caused by this species is rare compared with S.
Is Staphylococcus capitis spore forming?
Staphylococci are microbiologically characterized as gram-positive (in young cultures), non-spore-forming, nonmotile, facultative anaerobes (not requiring oxygen).
Is Staphylococcus capitis contagious?
Staph infections are contagious through person-to-person contact. If an individual with staph has a wound that oozes, someone who comes into contact with this liquid can contract the infection.
Where is Staphylococcus capitis found?
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.
What are the symptoms of Staphylococcus in a woman?
The most common type of staph infection is the boil, a pocket of pus that develops in a hair follicle or oil gland. The skin over the infected area usually becomes red and swollen. If a boil breaks open, it will probably drain pus. Boils occur most often under the arms or around the groin or buttocks.
Are there any new subspecies of Staphylococcus capitis?
A new subspecies, Staphylococcus capitis subsp. ureolyticus, was isolated from human skin and is described on the basis of studies of 15 to 26 strains. DNA-DNA reassociation reactions demonstrated that these strains were closely related to Staphylococcus capitis but were significantly divergent. The …
What kind of infection is Staphylococcus capitis associated with?
S. capitis. 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.
How big does a Staphylococcus capitis colony get?
– Staphylococcus capitis subsp. urealyticus Bannerman and Kloos 1991. pairs and clusters. after storage in the cold (4-10 ºC). Some strains become yellowish or yellow-orange. Colony diameter is 1-3 mm (subsp. capitis) or 4.3-7.1mm ( subsp.urealyticus). Facultatively anaerobic. optimum growth temperature is 37 ºC.
How are strains of Staphylococcus capitis subsp.ureolyticus distinguished?
The strains of S. capitis subsp. ureolyticus can be distinguished from S. capitis by their positive urease activity, their ability to produce acid from maltose under aerobic conditions, their fatty acid profile, and their colony morphology. The type strain of the new subspecies is strain ATCC 49326.
