What term refers to a disease-causing agent?

Explanation:
A disease-causing agent is called a pathogen. Pathogens include bacteria, viruses, fungi, and parasites—any organism or particle that can cause illness in a host. An endospore is a dormant, tough form some bacteria form to survive harsh conditions, not the disease-causing agent itself. A retrovirus is a specific type of virus, a subset of pathogens, while the lytic cycle describes how some viruses replicate and destroy cells, not the agent by itself. So the general term that covers all disease-causing agents is pathogen.
