I want to know the answer to the following question:
What are all multcellular organisms colonized to some degree by?
All the background I'm provided with is that "The difference between an infection and a colonization is often only a matter of circumstance. Non-pathogenic organisms can become pathogenic given specific conditions, and even the most virulent organism requires certain circumstances to cause a compromising infection.". Is that enough to answer the question?
Answer: no
