Campylobacter

Description and significance

Campylobacter is microaerophilic meaning it needs oxygen to survive, but the level of oxygen must be lower than the atmospheric levels. Too much oxygen and the bacterium could be killed. It is spiral in shape, a flagellate, and is very fragile. Campylobacter can be killed in high levels of oxygen or drying. Most campylobacter is found within the intestinal tract of animals such as dogs, cats, poultry, swine, cattle, monkeys, rodents, wild birds, and even within humans. In humans the bacteria can live and survive without causing illness although often it does. The bacteria cycles through the environment by traveling through the intestinal tracts of animals and exiting the body through feces. The feces is then incorporated into the soil which maintains the low level of oxygen. The animals eat plants and sometimes soil containing the bacteria and the cycle continues. Campylobacter can be found in untreated water that is contaminated with fecal matter and therefore contributes to the cycle of the bacteria. [1] and [2]

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?


Cell structure and metabolism

Interesting features of cell structure; how it gains energy; what important molecules it produces.


Ecology

Habitat; symbiosis; contributions to the environment.

Pathology

How does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.

Current Research and or Application to Biotechnology

Enter summaries of the most recent research and/or application to biotechnology here--at least three required
