Description and Significance

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

stages of P.vivax development

Appearance

P. vivax are parasites found inhabiting the liver and blood at various stages of development and shape. Starting as rings within red blood cells, then trophozoites as they develop within the red blood cells. Next, they form round gametocytes filling the red blood cells and schizonts which are elongated and wormlike, further filling out the red blood cells. Red blood cells infected by P. vivax cause swelling of the cell, increasing the size by approximately 1.5 times the size.

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 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.
