Description and significance
Helicobacter is a genus of proteobacteria that is found in a very acidic environment, a pH of 2.0 or less in the lining of the stomach and the duodenum. H.pylori is a Gram-negative organism that has a “helical shaped” body with about 6 to 8 flagella at one end. Under stressful environment conditions, the helical shape of the bacteria will change into a coccoid form. Helicobacter pylori were initially named Campylobacter pylordis, but after DNA sequencing, it was found that it didn’t belong to that genus. In 1989, H.pylori was separated into its own genus Helicobacter.
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?
