S. aureus |
Staphylococcus aureus are "potentially pathogenic bacteria found in nasal membranes, skin, hair follicles, and perineum of warm-blooded animals. They may cause a wide range of infections and intoxications."[1] S. aureus is so named because the bacteria form yellow clusters, as opposite to the white clusters of S. albus. The bacteria are Gram-positive.
Methicillin-resistant staphylococcus aureus
Methicillin-resistant staphylococcus aureus (MRSA) is a variety of staphylococcus that is resistant to commonly used antibiotics such as methicillin. MRSA has become an important public health problem.[2][3]
Numerous studies have looked at the role of decolonization to stop carriage.[4][5][6][7][8][9][10]
Whole body washing alone does not seem sufficient to reduce carriage.[11] Intranasal mupirocin with chlorhexidine soap body washing does not always suffice.mupirocin (group M) or placebo (group P) applied to the anterior nares for 5 days; both groups used chlorhexidine soap for body washing. Mupirocin alone may not work, especially in long-term care facilities[12] or military recruits[13].
A meta-analysis by the Cochrane Collaboration was inconclusive.[14]
