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.
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.
The type genus of this order is Enterobacter. [1] The name Enterobacterales is derived from the Latin term Enterobacter, referring the type genus of the order and the suffix "-ales", an ending used to denote an order. Together, Enterobacterales refers to an order whose nomenclatural type is the genus Enterobacter. [1]
Enterobacter cowanii is a Gram-negative, motile, facultatively-anaerobic, rod-shaped bacterium of the genus Enterobacter. The species is typically associated with natural environments and is found in soil, water, and sewage. [1] E. cowanii is associated with plant pathogens that exhibit symptoms of severe defoliation and plant death. [2]
The genus Hafnia is one of more than 40 genera that currently comprise the order Enterobacterales.. Although Møller originally described this genus in 1954, the legitimacy of this group was constantly challenged over the next two decades, often being referred to by synonyms such as "Enterobacter alvei", "Enterobacter aerogenes subsp. hafniae" and "Enterobacter hafniae" but it is mostly ...
Cronobacter is a genus of Gram-negative, facultatively anaerobic, oxidase-negative, catalase-positive, rod-shaped bacteria of the family Enterobacteriaceae.Several Cronobacter species are desiccation resistant and persistent in dry products such as powdered infant formula. [3]
Serratia species tend to colonize the respiratory and urinary tracts, rather than the gastrointestinal tract. Serratia infection is responsible for about 2% of nosocomial (hospital-acquired) infections of the bloodstream, lower respiratory tract, urinary tract, surgical wounds, and skin and soft tissues and other ailments that are commonly ...
Erwiniaceae, as of 2021, contains eight validly published genera. [2] Members of this family were originally members of the family Enterobacteriaceae, a large phylogenetically unrelated group of species with distinct biochemical characteristics and different ecological niches.
