What is characteristic of the relationship between a microorganism and the host during infection?

Both infection and colonization lack an immune response

Infection may not show clinical symptoms of the disease (correct)

The host's immune response is never responsible for disease manifestations

Penetrating the host organism

Resisting the effects of antibiotics
