Parasite-host interactions
Parasite-host interactions occur when a parasite lives on or inside a host organism, benefiting at the host's expense. Parasites feed on the host's nutrients, tissues, or fluids, often causing health problems or weakening the host's immune system. These relationships can range from mild, like lice on hair, to severe, such as tapeworm infections in the intestines. The parasite's goal is to survive and reproduce, while the host often faces consequences like illness or reduced vitality. Understanding these interactions helps in preventing and treating parasitic diseases, ultimately protecting health and wellbeing.
