The Enterobacteriaceae are a large family of Bacteria , including many of the more familiar Pathogen s, such as '' Salmonella '' and '' Escherichia Coli ''. Genetic studies place them among the Proteobacteria , and they are given their own order (Enterobacteriales), though this is sometimes taken to include some related environmental samples. Members of the Enterobacteriaceae are rod-shaped, and are typically 1-5 μm in length. Like other Proteobacteria they have Gram-negative stains, and they are Facultative Anaerobe s, Fermenting sugars to produce Lactic Acid and various other end products. They also reduce Nitrate to Nitrite . Unlike most similar bacteria, Enterobacteriaceae generally lack Oxidase , although there are exceptions (e.g. '' Plesiomonas ''). Most have many Flagella used to move about, but a few genera are non-motile. Many members of this family are a normal part of the Gut Flora found in the Intestines of humans and other animals, while others are found in water or soil, or are Parasites on a variety of different animals and plants. '' Escherichia Coli '', better known as ''E. coli'', is one of the most important Model Organism s and its Genetics and Biochemistry have been closely studied. The following genera are included here:
