What happens if antibiotics don't work for infection?

What is the resistance to infection?

Resistance is defined as the ability to limit pathogen burden while tolerance is defined as the ability to limit the health impact caused by a given pathogen burden. The sum of these two mechanisms defines a host's defensive capacity.

Can antibiotics make infections worse?
