Parasitic agents are organisms that live on or in a host, deriving nutrients at the host’s expense. They include protozoa, helminths (worms), and ectoparasites like lice and ticks.

Parasitic arthropods like ticks, mites, lice, and bed bugs exhibit parasitic behavior, feeding on the blood of hosts, causing discomfort, transmitting diseases, and sometimes leading to severe health issues.
