Shigiella is a non spore forming gram negative bacteria that aids in the facilitation of intracellular pathogens. It is able to survive the proteases and acids of the intestinal tract and infections to hosts can be caused from a very low dose. As little as 10 to 100 bacteria are needed to cause infection.

Classification

Higher order taxa

Bacteria; Proteobacteria; Gammaproteobacteria; Enterobacteriales; Enterobacteriaceae

Species

Shigella boydii; S. dysenteriae; S. flexneri; S. sonnei

Description and significance

Shigiella is a non spore forming gram negative bacteria that aids in the facilitation of intracellular pathogens. It is able to survive the proteases and acids of the intestinal tract and infections to hosts can be caused from a very low dose. As little as 10 to 100 bacteria are needed to cause infection.

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

Enter summarries of the most rescent research here--at least three required
