What is it called when a parasite kills its host?
In evolutionary ecology, a parasitoid is an organism that lives in close association with its host at the host's expense, eventually resulting in the death of the host.
Does a parasite eventually kills its host?
Parasites generally do not kill the host but may harm the host indirectly by spreading pathogens. This may affect the host's behaviour, metabolism or its reproductive activity.
How do parasites damage their host?
Toxins: Apart from disease and death, parasites can produce poisonous substances in the form of secretions, excretions or other products such as proteolytic enzymes and pigments. These can harm or sensitize the host, for example, Schistosome cercariae, Entamoeba histolytica and Malaria parasites [5].
