Anthrax oedema factor. Molecular model of oedema factor (EF) from the anthrax bacterium Bacillus antracis complexed with a calmodulin protein molecule. EF is one of three protein components that form the anthrax toxin. It is an enzyme that interferes with water homeostasis, leading to the accumulation of fluid in the tissues. Anthrax most commonly affects cattle, sheep and goats, but can also infect humans.

Cholera toxin, molecular model. Cholera toxin (choleragen) is a protein complex secreted by the bacterium Vibrio cholerae, that causes the disease cholera. It is made up of a wedge-shaped A subunit (right part of illustration) and five B subunits (left part of illustration) that form a ring which binds to the intestinal lining. In its most severe forms, cholera is one of the most rapidly fatal illnesses known.
Endosomes - 3d rendered image of Endosomes are membrane-bound organelles. They are parts of endocytic membrane transport pathway.  Endomembrane system in cells. Bilayer Lipid Membrane. Abstract medical illustration. Microscopic view. Microbiologic research concept.
Prions are misfolded proteins with the ability to transmit their misfolded shape onto normal variants of the same protein. They characterize several fatal and transmissible neurodegenerative diseases in humans and many other animals.
