Description and Significance
Edwardsiella ictaluri is a rod shaped, gram negative bacteria. They are small and motile, and anaerobic. It is typically found in freshwater and marine environments, typically present in the rivers of Japan, effecting Catfish, specifically channel catfish. It is found in the intestines of humans after eating an affected fish. When found on catfish, it is characterized externally by inflamed hemorrhagic foci on the skin which causes ulcers. This organism is important because of where it is found. Since we are in a coastal region, surrounded by oceans and channels/rivers, this bacteria could be found near us. It also impacts a food that our region eats often, catfish. This organism is very complex as well.
Genome Structure
Edwardsiella ictaluri Genome shows 43,378 bp in length with 2615 core genomes. It contains 5592 pan genes and one circular chromosome. The chromosome contains 3,630,639 base pairs. An interesting fact is that this bacteria is known as "hole in the head" and when it is found on catfish, they are called "hole in the head catfish". This microbe contains 59 hypothetical proteins and 12 predicted proteins.
Cell Structure, Metabolism and Life Cycle
Edwardsiella ictaluri is a gram-negative bacteria. It has a flagella, allowing movement. It is anaerobic, meaning that it makes energy without oxygen. This bacteria distinctly produces hydrogen sulfide.
Ecology and Pathogenesis
Habitat; symbiosis; biogeochemical significance; contributions to environment.
If relevant, how does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
