Most of us can, and most of us do defend against all kinds of attacks every day.

Bacteria, parasites, viruses, fungus, and a whole host of microorganisms are often called “opportunistic” meaning that they are common, but when a person’s defences are weak, or if they are exposed to a new attack their body is not prepared for, the attacker might win.

This amoeba is a big risk because our brains are very “soft targets”.

A brain infection can kill us.

Our immune response (fever, swelling) can also kill us.
