Query: NC_009348:3819271 Aeromonas salmonicida subsp. salmonicida A449, complete genome Lineage: Aeromonas salmonicida; Aeromonas; Aeromonadaceae; Aeromonadales; Proteobacteria; Bacteria General Information: Aeromonas salmonicida subsp. salmonicida A449 was isolated from a brown trout with furunculosis. The agent of furunculosis, a major cause of mortality among salmonid fishes. This bacterium is the causal agent of furunculosis. Although it was discovered nearly 100 years ago, it is not known how the diesase is spread. Furunculosis is temperature sensistive, with acute cases occurring when the water is above 20 degrees C and chronic cases developing at temperatures below 13 degrees C. The acute form of the disease causes the fish to turn a dark color and stop eating.

General Information: This strain is an isolate from an epidemic that took place in China in the 1950s. Causes dysentery. This genus is named for the Japanese scientist (Shiga) who first discovered these organisms in the 1890s. They are closely related to the Escherichia group, and may be considered the same species. These organisms are human-specific pathogens that are transmitted via contaminated food and water and are the leading causes of endemic bacillary dysentery, causing over 160 million cases of infection and 1 million deaths yearly worldwide. The bacteria infect the epithelial lining of the colon, causing acute inflammation by entering the host cell cytoplasm and spreading intercellularly. are extremely virulent organisms that can cause an active infection after a very low exposure. Both the type III secretion system, which delivers effector molecules into the host cell, and some of the translocated effectors such as the invasion plasmid antigens (Ipas), are encoded on the plasmid. The bacterium produces a surface protein that localizes to one pole of the cell (IcsA) which binds to and promotes actin polymerization, resulting in movement of the bacterium through the cell cytoplasm, and eventually to neighboring cells, which results in inflammatory destruction of the mucosal lining. Shigella boydii is uncommon except in India, where it was first isolated. Progression to clinical dysentery occurs in most patients infected with this organism.
