Common Infections(MRSA)

Commonly infected by Staphylococcus aureus(also known as "golden staph") which may contribute to dermatitic skin lesions in patients with atopic dermatitis http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=9178147&dopt=Abstract. The anterior nares can act as a colonizing point from which the infection can spread to other areas (and they should probably be checked in the case of a reoccuring staph infection)http://www.podiatrytoday.com/article/2452 and http://depts.washington.edu/ictrain/icmanual/guidephys.htm. This can be particularly troublesome if the strain is an antibiotic resistant (commonly MRSA or ORSA) strain. MRSA (first discoverd in the UK in 1961) has become particularly widespread in hospitals and is commonly considered a superbug. For more information on symptoms and treatment see MRSA.
