Organisms that can cause disease are called what?

Explanation:
Disease-causing organisms and agents are called pathogens. Pathogens include bacteria, viruses, fungi, protozoa, and other agents that can trigger illness in a host. The key idea is that pathogen is the broad term for anything that can cause disease, so it covers all these different types. The other options are specific groups that can cause disease, not the general category; they’re examples of pathogens rather than the umbrella term.
