Edwardsiella is a genus of gram-negative , peritricho flagellated , short rod bacteria . They belong to the Enterobacteriaceae family. Six Edwardsiella species are currently (2020) described. They are very similar to Escherichia coli . Organisms of the genus Edwardsiella are found in freshwater and on cold-blooded animals such as fish, reptiles, and amphibians. Occasionally they have been found in birds and mammals. Edwardsiella spp. show positive lysine and onithine decarboxylase activity. You react negatively to the Voges-Proskauer test . You can't use citric acid as the only source of carbon. Many clinical isolates of E. tarda form hydrogen sulfide on Salmonella-Shigella agar. Only E. tarda has been implicated in human diseases.
E. tarda intestinal infection usually manifests as acute secretory enteritis caused by the consumption of raw fish or snake meat. E. tardia can also cause severe wound infections and even sepsis . Edwardsiella piscicida is the etiological cause of Edwardsiellosis in fish and a major problem in aquaculture.
