The genome structure has been decoded for two of the three sub-species of Yersinis pestis, the KIM strain and the CO92 strain. The chromosome of the KIM strain contains 4,600,755 base pairs and the chromosome of the CO92 strain has 4,653,728 base pairs. Yersinia pestis is also the host to the plasimds pCD1, pPCP1, and pMt1 which along with a pathogenicity island called HPI encode the proteins that cause the infamous pathogenicity of the bacteria. These virulence factors are essential for the invasion of the bacteria into the host, and the injection of its proteins into the cell. | The genome structure has been decoded for two of the three sub-species of Yersinis pestis, the KIM strain and the CO92 strain.

Description and significance
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
How does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
Application to Biotechnology
Does this organism produce any useful compounds or enzymes? What are they and how are they used?
