Description:
A genus of gram-negative, facultatively anaerobic, rod-shaped bacteria of the family Enterobacteriaceae. They are occasional opportunistic pathogen for humans.
They occur in three species:
Edwardsiella hoshinae, a motile species that, isolated from animals and humans, does not produce indole.
Edwardsiella ictaluri, a nonmotile species that does not produce indole, occurring as a pathogen of catfish.
Edwardsiella tarda, also known as Edwardsiella anguillimortifera, a species which produces indole and is biochemically similar to Escherichia coli. It usually found in aquatic animals and reptiles and is found in the intestinal tract of snakes and seals. It is occasionally isolated from the urine, blood, and faeces of humans and has been known to cause gastroenteritis and wound infections. In India it has been found in children with diarrhoea.
Fermentation (biochemistry)
Fermentation is the process of extracting energy from the oxidation of organic compounds, such as carbohydrates, using an endogenous electron acceptor, which is usually an organic compound. In contrast, respiration is where electrons are donated to an exogenous electron acceptor, such as oxygen,...
