Description and significance

Shigella boydii is a bacillary (rod-shaped) gram negative bacterium. Evolutionarily, Shigella bacteria are thought to be derived from different strains of Escherichia coli although some serotypes of Shigella boydii seem to be more closely related to other species. S. boydii type 13, for example, shares sequence similarities with Vibrio cholerae for the genes encoding the O antigen, the polysaccharide part of the lipopolysaccharide, and therefore these may be more closely related.

Describe the appearance, habitat, etc. of the organism, and why it is important enough to have its genome sequenced. Describe how and where it was isolated. Include a picture or two (with sources) if you can find them.

Genome structure

Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence? Does it have any plasmids? Are they important to the organism's lifestyle?

Cell structure and metabolism

Describe any interesting features and/or cell structures; how it gains energy; what important molecules it produces.

Ecology

Describe any interactions with other organisms (included eukaryotes), contributions to the environment, effect on environment, etc.

Pathology

Known to cause diarrhea and Shigellosis (bacillary dysentery) through oral-fecal transmission. Less than 10% of foodborne illnesses are attributed to Shigella bacteria in the United States.2

Application to Biotechnology

Does this organism produce any useful compounds or enzymes? What are they and how are they used?

Current Research
