It is an uncommon human pathogen, most commonly as an opportunistic nosocomial infection. One hospital in Spain reported the organism to represent 0.4% of clinical Enterobacter isolates. Risk factors include prolonged hospital stays, "immunosuppression, the presence of a foreign device, prior use of anti-microbial agents in the patient involved ...
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.
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 infections. Infections caused by C. koseri can lead to ...
Pseudescherichia vulneris is a Gram-negative bacterial species. P. vulneris is a fermentative, oxidase-negative, motile rod, which holds characteristics of the family Enterobacteraceae. This bacterium can colonize in the respiratory tract, genital tract, stool, and urinary tract.
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.
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.
