Description and Significance
Describe the appearance, habitat, etc. of the organism, and why you think it is important.
Akkermansia muciniphila is an anaerobic, Gram-negative, non-motile, non-spore-forming, oval-shaped bacterium.[] It is present in the human intestinal tract in high quantities, ranging from 39% to 84% of the total bacterial population. A.muciniphila is associated with the protective mucus lining of the intestines. Its presence in the mucus layer of the intestinal tract is particularly important because A.muciniphila is able to degrade host mucin into short chain fatty acids, or other products, to regulate the biological functions of the host.[] The high content of Akkermansia muciniphila is thought to play a major role in the health of the intestinal mucos, as well as regulate host immune responses and lipid metabolism. [] Many studies have noticed that a decrease of Akkermansia muciniphila in the mucus is tied with higher rates of obesity, increased inflammation, and an increase in Type 2 diabetes symptoms. []
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?
The complete genome of Akkermansia muciniphila has one circular chromosome of 2,664,102 bp with a G+C content of 55.8%.Akkermansia muciniphila has a total of 2,176 protein coding sequences and an overall coding capacity of 88.8%.[]
Cell Structure, Metabolism and Life Cycle
Interesting features of cell structure; how it gains energy; what important molecules it produces.
Ecology and Pathogenesis
Habitat; symbiosis; biogeochemical significance; contributions to environment.
If relevant, how does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
