3D printout: molecular structure of cholera

A killer of human gut cells that tricks a human protein into helping it: Cholera. Every parasite that aims to invade or usurp another living cell needs to get an unwilling partner to do its dirty work somehow.

The three fit together almost perfectly, as you can see.
