These bacteria have a rod shape with a typical length of 1–5 μm. Most C. freundii cells have several flagella used for locomotion, although some non-motile taxa do not. C. freundii is a soil-dwelling microorganism, but can also be found in water, sewage, food, and the intestinal tracts of animals and humans. The genus Citrobacter was ...
The species C. amalonaticus, C. koseri, and C. freundii can use citrate as a sole carbon source. Citrobacter species are differentiated by their ability to convert tryptophan to indole (C. koseri is the only citrobacter to be commonly indole-positive), ferment lactose (C. koseri is a lactose fermentor), and use malonate.
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.
It is the second largest of the human body and made of various bacteria, viruses, fungi and protozoa. [14] These organisms play an important role in oral and overall health. Anthony Van Leeuwenhoek was the first to view these organisms using a microscope he created. [14]

Coliform bacteria are defined as either motile or non-motile Gram-negative non-spore forming bacilli that possess β-galactosidase to produce acids and gases under their optimal growth temperature of 35–37 °C. [1] They can be aerobes or facultative aerobes, and are a commonly used indicator of low sanitary quality of foods, milk, and water. [2]
Coliform bacteria include genera that originate in feces (e.g. Escherichia, Enterobacter, Klebsiella, Citrobacter). The fecal coliform assay is intended to be an indicator of fecal contamination; more specifically of E. coli which is an indicator microorganism for other pathogens that may be present in feces.
C. rodentium is an extracellular pathogen of rodents. [1] While its specific structure has not been characterized in detail, several characteristics of this species can be inferred by its classification. As a member of the Enterobacteriaceae family, it is Gram-negative, rod-shaped, and non-spore-forming.
