These bacteria pose a great threat to public health due to the limited treatment options available as well as lack of newly developed antimicrobial medications. MDR strains of Enterobacteriaceae, Pseudomonas aeruginosa, and Acinetobacter baumannii have become of most concern because they have been reported by hospitals all around the United ...
The genus Klebsiella was named after the German microbiologist Edwin Klebs (1834–1913). [citation needed] It is also known as Friedlander's bacillum in honor of Carl Friedländer, a German pathologist, who proposed that this bacterium was the etiological factor for the pneumonia seen especially in immunocompromised individuals such as people with chronic diseases or alcoholics.
Klebsiella is a genus of Gram-negative, oxidase-negative, rod-shaped bacteria with a prominent polysaccharide-based capsule. [ 3 ] Klebsiella is named after German-Swiss microbiologist Edwin Klebs (1834–1913).
ESKAPE is an acronym comprising the scientific names of six highly virulent and antibiotic resistant bacterial pathogens including: Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter spp. [1] The acronym is sometimes extended to ESKAPEE to include Escherichia coli.

Klebsiella aerogenes, [2] previously known as Enterobacter aerogenes, is a Gram-negative, oxidase-negative, catalase-positive, citrate-positive, indole-negative, rod-shaped bacterium. [3] Capable of motility via peritrichous flagella, [ 4 ] it is approximately one to three microns in length.
Meropenem/vaborbactam retains antimicrobial activity against class A and class C β-lactamase-producing Enterobacterales, especially those producing ESBL, KPC, and AmpC determinants. Meropenem/vaborbactam is also active against strains of Enterobacterales producing other types of class A serine carbapenemases (e.g. SME and NMC-A enzymes).
[14] [15] It is active against UTIs caused by Staphylococcus saprophyticus, Enterococci (e.g., Enterococcus faecalis), Escherichia coli, Klebsiella pneumoniae, and Proteus mirabilis. [15] It is a definitive treatment against susceptible extended-spectrum β-lactamase (ESBL)-producing Gram-negative bacteria. [15]
The NDM-1 enzyme is one of the class B metallo-beta-lactamase; other types of carbapenemase are class A or class D beta-lactamases. [11] (The class A Klebsiella pneumoniae carbapenemase is currently the most common carbapenemase, which was first detected in North Carolina, United States, in 1996 and has since spread worldwide.
