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 ...
Produces extracellular superoxide under selected growth conditions that can generate chromosomal instability in mammalian cells [22] [23] Resists intracanal medicaments (e.g. calcium hydroxide), although a study proposes elimination from root canals after using a mixture of a tetracycline isomer, an acid, and a detergent [24] Maintains pH ...

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. It is the type genus of the order Enterobacterales. [1]
The optimal growing conditions of this organism is in a facultative anaerobic environment with an average temperature of about 40 °C. The Becton/Dickinson BBL Enterotube II system for identification of members of the order Enterobacterales inoculated with P. vulgaris may yield the following results:
Klebsiella is a genus of Gram-negative, oxidase-negative, rod-shaped bacteria with a prominent polysaccharide-based capsule. [3]Klebsiella is named after German-Swiss microbiologist Edwin Klebs (1834–1913).
Enterobacter cloacae is a member of the normal gut flora of many humans and is not usually a primary pathogen. [9] Some strains have been associated with urinary tract and respiratory tract infections in immunocompromised individuals.
Klebsiella aerogenes, [2] previously known as Enterobacter aerogenes, is a Gram-negative, oxidase-negative, catalase-positive, citrate-positive, indole-negative, rod-shaped bacterium. [3]
