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. Some exclude ertapenem resistance from the definition.
Prevalence of carbapenem-resistant Enterobacteriaceae in paediatric intensive care units (Cairo, Egypt) was 24% and various genes of carbapenemases were detected in 80% of carbapenem-resistant Enterobacteriaceae with dominance of bla OXA-48. [38]
Several Enterobacteriaceae strains have been isolated which are resistant to antibiotics including carbapenems, which are often claimed as "the last line of antibiotic defense" against resistant organisms. For instance, some Klebsiella pneumoniae strains are carbapenem resistant. [18]
The concern is that carbapenem is often used as a drug of last resort when battling resistant bacterial strains. New slight mutations could result in infections for which healthcare professionals can do very little, if anything, to treat patients with resistant organisms. A number of mechanisms cause carbapenem resistance in the Enterobacteriaceae.
The evolution of bacteria on a "Mega-Plate" petri dish A list of antibiotic resistant bacteria is provided below. These bacteria have shown antibiotic resistance (or antimicrobial resistance). Gram positive Clostridioides difficile Clostridioides difficile is a nosocomial pathogen that causes diarrheal disease worldwide. Diarrhea caused by C. difficile can be life-threatening. Infections are ...
Nacubactam is an investigational β-lactamase inhibitor being developed for the treatment of infections caused by carbapenem-resistant Enterobacteriaceae (CRE). It belongs to the diazabicyclooctane (DBO) class of compounds and exhibits a dual mechanism of action.

Enterobacter huaxiensis and Enterobacter chuandaensis are two recently discovered species that exhibit especially antibiotic resistant characteristics. [9] Cefepime, a fourth-generation cephalosporin from the β-Lactam antibiotic class. [more detail needed] Imipenem (a carbapenem) is often the antibiotic of choice.
