Klebsiella aerogenes, [2] previously known as Enterobacter aerogenes, is a Gram-negative, oxidase-negative, catalase-positive, citrate-positive, indole-negative, rod-shaped bacterium. [3]
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 ...
It is a member of the family of Enterobacteriaceae. The members of this family are part of the normal flora and commonly found in the digestive tracts of humans and animals. C. koseri may act as an opportunistic pathogen in individuals who are immunocompromised. [3] It rarely is community-acquired and mainly occurs as hospital-acquired ...
Enterobacter is a genus of common Gram-negative, facultatively anaerobic, rod-shaped, non-spore-forming bacteria of the family Enterobacteriaceae. Cultures are found in soil, water, sewage, feces and gut environments.
Enterobacteriaceae is a large family of Gram-negative bacteria. It includes over 30 genera and more than 100 species. 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 ...
C. freundii is more phylogenetically diverse than the clades of E. coli and Salmonella spp., indicating C. freundii to be a polyphyletic genus. [4] Due to the phenotypic diversity that C. freundii contains, it makes it very difficult to identify, especially because it is versatile not only in its antigenic and pathogenic behaviors, but also in its cell morphology.
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]
The identification of E. corrodens may be delayed because of its slow growth in the absence of CO 2. [16] E. corrodens can be treated with penicillins , cephalosporins , or tetracyclines , however due to the resistant nature of the bacteria ongoing and recurring symptoms can be expected despite rigorous and prolonged antibiotic treatment.
