MRSA is genetically unique bacteria which causes infections in human which are difficult to treat due to the organisms' antibiotic resistant nature.


MRSA or Methicillin Resistant Staph Aureus contains a gene which is responsible for its resistance against Methicillin (or other similar penicillin derivatives) action, hence the drug can't kill it.

This type of resistance is obtained by transduction, a horizontal gene transfer process in which foreign genes are transferred by plasmid to a bacterial genome. First identified in 1960s, such resistant bacteria are now reported from most hospitals.
