Description and Significance

Describe the appearance, habitat, etc. of the organism, and why you think it is important.

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

Identification during a transmission electron micrograph showed multiple bacterial vacuoles expanding in the cell cytoplasm. The bacterium typically had vacuolar membrane but in advanced infections they didn't have the vacuolar membrane and directly interacted with the host cell cytoplasm. Most bacterium presented a pill-like structure expanding around the bacteria cell as well as a fibrous inclusion body. Their life cycle consist of binary fission. Region 1 of the genome contains 12 protein coding genes which also consist of metabolic proteins. The bacterium also has multiple semi-conserved biosynthetic secondary metabolite clusters.

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.
