Description and Significance

"Bifidobacterium animalis" is a branched, rod-shaped (diplobicillus) gram-positive bacteria. This bacteria is generally found in the large intestines of mammals such as: cats, cows, and humans. Discovered by Henry Tissier in 1900 "Bifidobacterium animalis" was isolated from a breast-fed infant¹.

Although it was discovered in 1900, research on this bacterium did not ensue until the interest in probiotics in 1950. Probiotics are microorganisms that are ingested either in combination or as a single organism in an effort to normalize intestinal microbiota and potentially improve intestinal barrier function². It has long been speculation that probiotics are useful in alleviating or curing the symptoms associated with Irritable Bowel Disease (IBD) like ulcerative collitis.

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, Metabolism and Life Cycle

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


Ecology

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.
