Methicillin-resistant Staphylococcus aureus (MRSA) - commonly known as 'Staph,' is an infection- causing strain of Staphylococcus bacteria that is resistant to a range of antibiotics, particularly Methicillin. A 2009 research has revealed that many antibiotic-resistant genes and toxins are collectively transferred from one bacterium to another and this explains the speed at which antibiotic resistance develops in Staph bacteria earning it the dubious but awe- inspiring name of 'superbug'.
