CRE infection, or Carbapenem-resistant Enterobacteriaceae infection, is caused by bacteria that are resistant to carbapenem. This serves as the best and last option of antibiotic class when other antibiotics fail to handle severe contaminations. These bacteria have been dubbed as “nightmare bacteria” because they have developed resistance to all antibiotics currently available, making CRE infections highly difficult to manage and possibly fatal. Furthermore, the individuals at high risk of this kind of infection are people with health problems, patients in the hospital, and even any age.
