Description and Significance
Shewanella algae is a gram-negative, rod-shaped, motile bacilli with a single polar flagellum. S. algae is found in warm Marine environments throughout the world, and is isolated form seawater at with 15-20% salinity (Holt 2005).
Shewanella algae is of interest because of its potential to be a serious human pathogen. It is known to cause peritonitis and obstructive pneumonia, rupture of aortic aneurysm, ear infections (Beleneva 2009) bacteraemia, rare occurrences of skin and soft tissue infections (Myung 2009), bone and joint infections, and many others (Holt 2005).
In the past, its effects has often been attributed wrongly to Shewanella putrefaciens. There has been a rising number of disease cases attributed to S. algae in the last decade, thanks to correct classification.
Shewanella algae is associated with bacterial peritonitis. The species is also of interest because of its potential to treat radioactive waste in groundwater. It has the ability to reduce uranium and plutonium by reducing soluble forms to insoluble forms (Mulvany 2010).
