Microbiological analysis of the nasal discharge or smear is used to check for the presence of Staphylococcus aureus.
More information
Colonization of the nasal cavities with Staphylococcus aureus increases the risk of staphylococcal infections elsewhere in the body, such as surgical incisions and dialysis sites. It is also associated with recurrent skin infections and hospital infections in nurseries and hospitals. Staphylococcus aureus is a significant cause of morbidity and mortality in patients undergoing dialysis, as most carry the microorganism in their nasal cavities.
Eliminating nasal carriage of Staphylococcus aureus may be beneficial in some clinical situations. In addition to topical therapy, systemic therapy may also be used to control patients' nasal colonization when they have an infection elsewhere. Topical antibacterial agents, such as chlorhexidine/neomycin, are preferred when the patient is designated as a carrier only.
Nasal smear microbiological analysis can detect the presence of group A streptococci (Lancefield) and methicillin-resistant Staphylococcus aureus (MRSA).
Rhinoscleroma, a disease caused by Klebsiella rhinoscleromatis infection, is a rare form of chronic granulomatous nasal infection that affects the nasal passages and sinuses and can also include the pharynx and larynx. The disease is progressive and manifests itself with local inflammation and enlargement that resembles a tumor. Although ordinary in Eastern Europe, Central Africa, Latin America, and Southeast Asia, rhinoscleroma is only slightly contagious.
Ozaena (ozena) is a chronic atrophic rhinitis that can damage the mucosa. It is characterized by a chronic, often purulent, foul-smelling, runny nose. Klebsiella ozaena may have a causal role.
Important Note
Laboratory test results are the most important parameter for diagnosing and monitoring all pathological conditions. 70% to 80% of diagnostic decisions are based on laboratory tests. Correct interpretation of laboratory results allows a doctor to distinguish "healthy" from "diseased."
Laboratory test results should not be interpreted from the numerical result of a single analysis. Test results should be analyzed based on each case and family history, clinical findings, and other laboratory tests and information. Your physician should explain the importance of your test results.
At Diagnostiki Athinon, we answer any questions you may have about the test you perform in our laboratory and contact your doctor to ensure you receive the best possible medical care.
