Enterobacteriaceae is a large family of Gram-negative bacteria.It includes over 30 genera and more than 100 species. Its classification above the level of family is still a subject of debate, but one classification places it in the order Enterobacterales of the class Gammaproteobacteria in the phylum Pseudomonadota.
"Enterobacteriales" was a monotypic order, containing only the family Enterobacteriaceae, and shared its type genus Escherichia. [2] [3] [4] The order contained a large, diverse group of species, occupying distinct ecological niches and possessing a variety of biochemical characteristics. [5]
For Enterobacter species, the flagella is used for adhesion, biofilm formation, and protein export as well as motility. Between the strains, the microbial genus produces endotoxins unique to the species. [7] As a gram negative bacterium, the lipopolysaccharide capsule helps to avoid phagocytosis and can initiate inflammatory response.
Resistance to carbapenem among Enterobacteriaceae and other gram-negative bacteria can be acquired through several mechanisms. Active transport of carbapenem drugs out of the cell, augmented drug efflux, has been observed in some resistant species. [citation needed]

Escherichia (/ ˌ ɛ ʃ ə ˈ r ɪ k i ə / ESH-ə-RIK-ee-ə) is a genus of Gram-negative, non-spore-forming, facultatively anaerobic, rod-shaped bacteria from the family Enterobacteriaceae. [3] In those species which are inhabitants of the gastrointestinal tracts of warm-blooded animals, Escherichia species provide a portion of the microbially ...
The species of Klebsiella are all gram-negative and usually non-motile. They tend to be shorter and thicker when compared to others in the family Enterobacteriaceae. Klebsiella species are found everywhere in nature. This is thought to be due to distinct sublineages developing specific niche adaptations, with associated biochemical adaptations ...
Serratia is a genus of Gram-negative, facultatively anaerobic, rod-shaped bacteria of the family Enterobacteriaceae. [5] They are typically 1–5 μm in length, do not produce spores, [6] and can be found in water, soil, plants, and animals. [7]
