Carbapenem-resistant Enterobacteriaceae (CRE) or carbapenemase-producing Enterobacteriaceae (CPE) are gram-negative bacteria that are resistant to the carbapenem class of antibiotics, considered the drugs of last resort for such infections. They are resistant because they produce an enzyme called a carbapenemase that disables the drug molecule ...
Multidrug resistant Gram-negative bacteria (MDRGN bacteria) are a type of Gram-negative bacteria with resistance to multiple antibiotics. They can cause bacteria infections that pose a serious and rapidly emerging threat for hospitalized patients and especially patients in intensive care units. [1] Infections caused by MDR strains are ...
Several strains of these bacteria are pathogenic and cause opportunistic infections in immunocompromised (usually hospitalized) hosts and in those who are on mechanical ventilation. The urinary and respiratory tracts are the most common sites of infection. The genus Enterobacter is a member of the coliform group of bacteria.
The emergence of highly resistant strains of M. morganii have been associated with use of third-generation cephalosporins. [3] Polymicrobial infections are most abundantly caused by this microbe which additionally damages the skin, soft tissues, and urogenital tract; these can be cured through use of the aforementioned antibiotics.

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 ...
Bacteroides fragilis is an anaerobic, Gram-negative, pleomorphic to rod-shaped bacterium. It is part of the normal microbiota of the human colon and is generally commensal, [1] [2] but can cause infection if displaced into the bloodstream or surrounding tissue following surgery, disease, or trauma. [3]
Proteus penneri is a Gram-negative, facultatively anaerobic, rod-shaped bacterium. [1] It is an invasive pathogen [2] and a cause of nosocomial infections of the urinary tract or open wounds. [3] Pathogens have been isolated mainly from the urine of patients with abnormalities in the urinary tract, and from stool. [4]
Gram-negative bacteria are bacteria that, unlike gram-positive bacteria, do not retain the crystal violet stain used in the Gram staining method of bacterial differentiation. [1] Their defining characteristic is that their cell envelope consists of a thin peptidoglycan cell wall sandwiched between an inner ( cytoplasmic ) membrane and an outer ...
