The particular bacterium responsible for MRSA infection is staphylococcus aureus, according to WebMD. When the staph bacterium withstands treatment from one antibiotic in the penicillin group called methicillin, the bacterium is referred to as methicillin-resistant staphylococcus aureus, or MRSA. It is known in the medical field as a "super bug."
In the United States, staph bacteria have been identified as one of the leading causes of skin-related diseases. Since its initial discovery in 1961, the MRSA strain has become a grave threat to the general well-being of the people. MRSA infections can result in pneumonia, sepsis and even death in some instances, as reported by the New York Department of Health.
