Phenotypic methods for MRSA detections.

Staphylococcus is one of the most notorious and important human pathogen that has long been recognized for its ability to cause serious and invasive diseases. In 1881 Sir Ogeston isolated these bacteria from human abscess pus and identified as grape like clusters. Later in the year 1884, Rosenbach on the basis of pigment production differentiated species of staphylococci. Strain producing golden yellow pigment (Staphylococcus aureus) considered as pathogenic where as white pigment producers S. albus(later renamed S.epidermidis) considered as non- disease causing strain.
