A host in which no development of the parasite occurs, although its presence may be required as an essential link in the completion of the parasite's life cycle.

A non-human host, animal host that serves as the source of infection to humans. It canharbor a pathogen indefinitely with no ill effect.

Either a definitive, intermediate, or accidental host that allows the parasite to complete its life cycle in part or the whole.

A host organism other than true definitive host, which receives the parasite but the parasite finds itself in a dead end.

Transmits parasites from host to host.

A vector that is essential in life cycle of parasite.

A vector that is unessential in life cycle of parasite. It just help the parasite travel to a definitive host.

When the vector prefers human blood when it is available.

When the vector prefers animal blood when it is available.
