MRSA can be identified by swabbing the nostrils and isolating the bacteria found there. Combined with extra sanitary measures for those in contact with infected people, swab screening people admitted to hospitals has been found to be effective in minimizing the spread of MRSA in hospitals in the United States, Denmark, Finland, and the Netherlands.
Using aseptic technique, broth culture of a specific organism is collected with a sterile swab. In the case of Gram negative bacteria, excess liquid is removed from the swab by gently pressing or rotating it against the inside of the tube. The swab is then streaked across a Mueller–Hinton agar plate to form a bacterial lawn.
This test was recommended the standard by the Clinical and Laboratory Standards Institute in 2004 for its use against MRSA. [3] Testing for inducible clindamycin resistance is typically performed in strains of Staphylococcus , β-hemolytic streptococci, and Streptococcus pneumoniae that demonstrate erythromycin resistance and clindamycin ...
Methicillin-resistant Staphylococcus aureus (MRSA, often pronounced / ˈ m ɜːr s ə / or / ɛ m ɑːr ɛ s eɪ /), is one of a number of greatly feared strains of S. aureus which have become resistant to most β-lactam antibiotics.

MRSA ST398 is a clonal complex 398 (CC398). This means that the strain had emerged in a human clinic, without any obvious or understandable causes. MRSA ST398, a specific strain of MRSA, is commonly found in livestock, and can cause infections in humans who come into contact with infected animals. [1]
As of 2017, point-of-care resistance diagnostics were available for methicillin-resistant Staphylococcus aureus (MRSA), rifampin-resistant Mycobacterium tuberculosis (TB), and vancomycin-resistant enterococci (VRE) through GeneXpert by molecular diagnostics company Cepheid. [41]
