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.
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.
Cronobacter sakazakii, which before 2007 was named Enterobacter sakazakii, [2] [3] is an opportunistic Gram-negative, rod-shaped, pathogenic bacterium that can live in very dry places, a phenomenon known as xerotolerance. C. sakazakii utilizes a number of genes to survive desiccation [4] and this xerotolerance may be strain specific. [5]
Infections caused by C. koseri can lead to various symptoms, including fever, chills, diarrhea, and abdominal pain. In severe cases, the bacterium can cause sepsis, meningitis, or brain abscesses. Brain abscesses have a high rate of mortality and complications, particularly in neonates.
However, infection of pet animals is associated with diarrhea. [5] Further, human infections have been substantiated, with conclusive reports from Italy. The majority of these cases are among children less than 3 years old, who are more prone to oral contact with animal droppings. Symptoms are typified by diarrhoea with fever and acute ...
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 ...
Pantoea agglomerans is a Gram-negative bacterium that belongs to the family Erwiniaceae.. It was formerly called Enterobacter agglomerans, or Erwinia herbicola and is a ubiquitous bacterium commonly isolated from plant surfaces, seeds, fruit, and animal or human feces and can be found throughout a honeybee's environment.

Enterobacter taylorae is a Gram-negative bacteria formerly known as Enteric Group 19, and also known as Enterobacter cancerogenus. [1] Strains of E. taylorae are positive for: Voges-Proskauer, citrate utilization, arginine dihydrolase and malonate utilization. They ferment D-glucose and also ferment D-mannitol, L-rhamnose and cellobiose.
