Seven people have been infected by and two have died from carbapenem-resistant Enterobacteriaceae, a drug-resistant superbug.

Carbapenem-resistant enterobacteriaceae (CRE) is also considered an urgent threat.

Weeks later, she was back in the hospital fighting a life-threatening infection called carbapenem-resistant enterobacteriaceae -- or CRE.

CDC officials report that Carbapenem-resistant enterobacteriaceae are on the rise in U.S. hospitals.

Rapid emergence and spread of OXA-48-producing carbapenem-resistant Enterobacteriaceae isolates in Belgian hospitals.

CRE (Carbapenem-resistant enterobacteriaceae) is a new class of multidrug-resistant bacteria that have the ability to spread drug resistance to other bacteria.

CRE bacteria -- a family of germs called carbapenem-resistant Enterobacteriaceae, which includes E. Coli.

The family of germs, dubbed CRE for carbapenem-resistant Enterobacteriaceae, evades some the strongest antibiotics, making infections almost untreatable.

CRE, carbapenem-resistant Enterobacteriaceae, is a nightmare strain of bacteria that can resist all antibiotics, kill a high proportion of the people it infects and spread readily.

The bacteria, called carbapenem-resistant Enterobacteriaceae or CRE, have increased over the past decade and grown resistant to even the most powerful antibiotics, according to the CDC.

(CNN) -- The Centers for Disease Control and Prevention has sent out a warning to hospitals about a new antibiotic-resistant bacteria, carbapenem-resistant Enterobacteriaceae, or CRE.

In addition to resistant gonorrhea, the others now seen as urgent threats, according to the first-of-its-kind report released on Monday, are C. difficile and the killer class known as carbapenem-resistant Enterobacteriaceae, or CRE.

Carbapenem-resistant enterobacteriaceae (CRE) have been defined as carbapenem-nonsusceptible and extended-spectrum cephalosporin-resistant Escherichia coli, Enterobacter aerogenes, Enterobacter cloacae complex, Klebsiella pneumoniae, or Klebsiella oxytoca.

Carbapenem-resistant enterobacteriaceae (CRE) or Carbapenemase-producing Enterobacteriaceae (CPE), are gram-negative bacteria that are nearly resistant to the carbapenem class of antibiotics, considered the "drug of last resort" for such infections.

Just this March, the Centers for Disease Control and Prevention warned the public about a four-fold increase in one group of "nightmare bacteria," carbapenem-resistant Enterobacteriaceae, which kills up to 50% of the people infected, and is on the rise.

In the past few months, 11 people in Los Angeles who underwent surgical procedures using a device called a duodenoscope got sick-infected with a so-called superbug called CRE, carbapenem-resistant Enterobacteriaceae, likely carried by the scope from other patients the doctors used it on.
