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 ...
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.
Escherichia (/ ˌ ɛ ʃ ə ˈ r ɪ k i ə / ESH-ə-RIK-ee-ə) is a genus of Gram-negative, non-spore-forming, facultatively anaerobic, rod-shaped bacteria from the family Enterobacteriaceae. [3] In those species which are inhabitants of the gastrointestinal tracts of warm-blooded animals, Escherichia species provide a portion of the microbially ...
Medically-relevant gram-negative diplococci include the four types that cause a sexually transmitted disease (Neisseria gonorrhoeae [20]), a meningitis (Neisseria meningitidis [21]), and respiratory symptoms (Moraxella catarrhalis, [22] A coccobacillus Haemophilus influenzae is another medically relevant coccal type.
Klebsiella aerogenes, [2] previously known as Enterobacter aerogenes, is a Gram-negative, oxidase-negative, catalase-positive, citrate-positive, indole-negative, rod-shaped bacterium. [3]
Morganella morganii was first described by a British bacteriologist H. de R. Morgan in 1906 as Morgan's bacillus. Morgan isolated the bacterium from stools of infants who were noted to have had "summer diarrhea". [4] Later in 1919, Winslow et al. named Morgan's bacillus, Bacillus morganii. In 1936, though, Rauss renamed B. morganii as Proteus ...
Bacillary dysentery is a type of dysentery, and is a severe form of shigellosis.It is associated with species of bacteria from the family Enterobacteriaceae. [1] The term is usually restricted to Shigella infections.
P. vulneris has a rod-like (bacilli) shape, and it achieves motility using peritrichous flagella (covering the whole body of the bacteria). P. vulneris is facultatively anaerobic, and is not spore-forming. Optimal growth occurs at 35-37 °C, and it can colonize on a simple nutrient medium.
