4 Superbug profiles

MRSA Methicillin-resistant Staphylococcus aureus (MRSA) is a type of staph bacteria that is resistant to antibiotics known as beta-lactams. MRSA is passed on through skin-to-skin contact but can also be spread through bed linens, bathroom fixtures and medical equipment. The infections typically occur in hospitals and health-care facilities. If treated early, MRSA can be treated with antibiotics. [Photo: Fabrizio Bensch/Reuters]

C. difficile Clostridium difficile (C. difficile) bacteria are found in the feces. It can be passed on if a person touches an infected surface and then proceeds to touch their mouth. The bacterium can cause diarrhea as well as inflammation of the colon. In mild cases, patients do not need treatment but in severe instances, they may require medication or surgery. [Photo:CDC]

CRE This family of bacteria is very difficult to treat and can be deadly in patients. Carbapenem-resistant Enterobacteriaceae (CRE), which is found in the bowels and the feces, is very resistant to many types of antibiotics. CRE typically affects patients using ventilators, urinary catheters and intravenous catheters. [Photo:CDC]
