Avibactam is a diazobicyclooctane inhibitor of gram-negative and gram-positive bacteria.  Avibactam (red) inhibits the bacterial enzyme beta-lactamase (blue) of Clostridioides difficile.
Rendered coronavirus/2019-nCoV single-stranded RNA, built from experimentally determined Ebola virus crystal structure. Color symbols - bluewhite=carbon, pink=oxygen, lightblue=nitrogen, white=hydrogen, lavender=phosphorus
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.
