The classification of this organism has been subject to debate. Isolated over 100 years ago, it was originally termed Mycobacterium enteritidis chronicae pseudotuberculosae bovis johne [13]. Current classifications depend on genetic composition and phenotypic characteristics. With a genome almost identical to that of Mycobacterium avium (M. avium) and its subspecies, the International Association for Paratuberculosis has recognized the subspecies term (Map) as fitting. On the other hand, some researchers and organizations still use the name M. paratuberculosis, not only for simplicity, but as a result of its significant phenotypic variances from M. avium [3, 8].
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?
Current Research
MAP and Crohn's Disease
Methods of Detection
