Infectious agents are parasites that reproduce within the cells of other organisms, taking over their biochemical processes. These agents, which include viruses, bacteria, viroids, prions, and archaea, utilize the host's proteins, RNA, and DNA to create copies of themselves, often leading to cell death. They can infect in various ways, categorized by their structure and replication methods, including lytic and lysogenic cycles. This overview explores the complexities of how these agents propagate and the implications for host organisms.
