Description and significance
Campylobacter jejuni is a gram negative bacteria that is curved and rod-shaped. It is most commonly found in animal feces, especially in wombad, kangaroo and bird feces. Campylobacter jejuni is a microaerophilic organism, this means that it requires an environment that contains reduced concentration of oxygen (~3-5% of oxygen and ~2-10% of carbon dioxide). Because of this requirement, it is very sensitive to stress in the environment. For example, too much oxygen, acidic condition, heating, and drying. Campylobacter jejuni is the number one cause of foodborn illness in the United States. However, it is least deadly. 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?
