The epidemiology of Staphylococcus capitis infections is not well understood, but some studies have reported the following findings:
S. capitis is a common cause of human bloodstream infections (BSIs), especially among coagulase-negative staphylococci (CoNS) species. It can cause serious complications such as endocarditis, urinary tract infection, and catheter-related bacteremia.
it is particularly important in neonatal intensive care units (NICUs), where it causes up to 20% of cases of neonatal sepsis. It can also cause meningitis, osteomyelitis, and septic arthritis in newborns.
S. capitis is likely transmitted mainly via humans, primarily through skin contact or medical devices. It can also be acquired from the environment or the mother during delivery.
it has a high level of antibiotic resistance, especially to methicillin, aminoglycosides, and glycopeptides. Some strains may also resist multiple drugs, making them difficult to treat.
S. capitis has two subspecies: subsp. Capital and subsp. urealyticus. The former is more common on the head, while the latter can colonize other body parts during antibiotic therapy. The subspecies may differ in their virulence and resistance profiles.
S. capitis is a species of bacteria that can cause various human infections. It belongs to the taxonomical classification as follows:
Domain: Bacteria
Phylum: Firmicutes
Class: Bacilli
Order: Bacillales
Family: Staphylococcaceae
Genus: Staphylococcus
Species: Staphylococcus capitis
The structure of Staphylococcus capitis:
Morphology: Staphylococcus capitis is a gram-positive bacterium typically appearing as spherical or oval cells arranged in clusters, resembling grapes. It belongs to the Staphylococcus genus, characterized by its ability to form grape-like clusters.
Cell Wall: Like other Staphylococcus species, S. capitis has a thick peptidoglycan cell wall, which provides structural integrity to the bacterium. The cell wall also contains teichoic acids, which add to the total negative charge of the cell surface.
Capsule: S. capitis can produce a polysaccharide capsule, an additional layer outside the cell wall. The capsule helps protect the bacterium from the host immune system and enhances its ability to adhere to surfaces.
Surface Proteins: S. capitis possesses various surface proteins, including adhesins and biofilm-associated proteins. These proteins are essential in the bacterium’s ability to attach to host tissues and form biofilms, which are communities of bacteria encased in a matrix.
Biofilm Formation: S. capitis could form biofilms on different surfaces, such as medical devices and human tissues. Biofilms protect bacteria from antimicrobial agents and host defenses, making them more resistant to treatment and associated with persistent infections.
There are two subspecies of S. capitis: subsp. Capital and subsp. urealyticus. The former is more common on the head, while the latter can colonize other body parts during antibiotic therapy.
The antigenic types of S. capitis infections are not well studied, but some studies have reported the presence of poly-γ-glutamic acid and endopeptidase ALE-1 as potential virulence factors that help the bacteria evade host immune response and form biofilms. S. capitis can also produce phenol-soluble modules and exoproteins, possibly contributing to its pathogenicity.
S. capitis infections are usually treated with antibiotics, but some strains may resist multiple drugs, including methicillin and fluoroquinolones. Therefore, it is essential to perform susceptibility testing and choose appropriate antibiotics for each case.
Staphylococcus capitis pathogenesis refers to how this bacterium causes infections in humans or animals. According to web sources, S. capitis is an opportunistic pathogen that can cause biofilm-related infections such as endocarditis, urinary tract infection, and catheter-related bacteremia. S. capitis is usually harmless for healthy people but can infect people with weak immune systems or artificial heart valves.
Some virulence factors of S. capitis include biofilm formation, poly-γ-glutamic acid, endopeptidase ALE-1, and phenol-soluble modules and exoproteins. S. capitis can attach to the surface of medical devices or tissues and form a slimy biofilm that protects it from the host’s immune response and antibiotic therapy. S. capitis can also produce toxins and enzymes that damage the host cells and tissues.
Host defenses of S. capitis infections are the mechanisms by which the human body tries to eliminate or control the bacteria and prevent disease.
Some of the host defenses of S. capitis infections are:
Physical barriers are provided by the skin & mucous membranes that prevent the entry of S. capitis into the body.
The innate immune system recognizes and attacks S. capitis through various cells and molecules, such as neutrophils, macrophages, complement, and antimicrobial peptides.
Specific antibodies are produced by the adaptive immune system T cells that target S. capitis and enhance the clearance of the bacteria.
The inflammatory response triggers local and systemic reactions that aim to contain and eliminate the infection, such as redness, swelling, pain, fever, and leukocytosis.
However, S. capitis can evade or overcome some of these host defenses by producing various virulence factors, such as biofilm, toxins, enzymes, and resistance genes. Therefore, host defenses alone may not be sufficient to prevent or treat S. capitis infections, and additional measures such as hygiene, disinfection, and antibiotics may be required.
Staphylococcus capitis is a type of staph bacteria that lives on the skin of the human scalp, face, neck, and ears. It is usually harmless for healthy people but can induce infections in patients with compromised immune systems and artificial heart valves. The symptoms of Staphylococcus capitis infection may vary based on the location & intensity of the infection.
Some possible symptoms are:
Skin infections: These may appear as white or greyish colonies on the skin that are smooth, slightly convex, glistening, and opaque. They may change color to yellow or yellow-orange after storage at low temperatures.
Endocarditis: This is an inner lining disease of the heart valves. Valves or chambers. It can be caused by Staphylococcus capitis bacteria that travel through the bloodstream from another site of infection. Symptoms include fever, chills, fatigue, shortness of breath, chest pain, and a new or changed heart murmur.
Device-related infections: Staphylococcus capitis bacteria can cause infections due to inserting medical devices like cardiac devices, orthopedic devices, and central nervous system shunts. Symptoms include erythema, pain, purulence around the site of the infection, and sepsis.
Staphylococcus capitis infections can be diagnosed by various methods, such as:
Cultural and biochemical characteristics: Staphylococcus capitis bacteria can be isolated from clinical specimens such as blood, pus, or tissue and grown on different media types. The colonies can be identified by size, shape, color, and hemolysis pattern. The bacteria can also be tested for their ability to ferment different sugars, produce coagulase enzymes, and hydrolyze urea.
Rapid identification kits: These commercial kits use different tests, such as latex agglutination, immunochromatography, or PCR, to identify Staphylococcus capitis bacteria within a few hours or minutes.
Molecular diagnosis involves using techniques such as DNA sequencing, PCR, or MALDI-TOF mass spectrometry to detect and identify Staphylococcus capitis bacteria based on their genetic or proteomic profiles.
Some of the ways to prevent S. capitis infections are:
Maintaining proper hygiene and routinely washing. Using water, soap, or a hand sanitizer with alcohol, wash your hands.
Avoid contact with people who have S. capitis infections or wounds.
Keeping your skin healthy, moisturized, and promptly treating cuts or scrapes.
Cleaning and disinfecting any medical devices or equipment that encounter your skin or blood, such as catheters, prosthetic valves, or joint implants.
Seeking medical attention if you develop any signs or symptoms of S. capitis infection, such as fever, chills, redness, swelling, pain, or pus.
Following your doctor’s advice on the appropriate use of antibiotics and completing the prescribed course of treatment.
