An intermediate host is an animal that is needed for a parasite to develop through one or more stages of life before being transferred to a definitive host in which the parasite will develop into sexual maturity. A reservoir host is a host that may be an intermediate or definitive host but provides a place where a parasite may "hang out" while enviromental conditions are less than optimal.
Cow: Intermediate host to the larval stages of beef tapeworm (Taenia saginata)
Infective stage is the life cycle stage where parasite able to initiate an infection in a definitive or intermediate host. Diagnostic stage is the life cycle stage leaving the definitive host, it is the stage that links the parasitic way of life with either the free-living phase of the life cycle or the phase of development that occurs in an intermediate host.

Intermediate host - snail definitive host - cattle/sheep
The eggs of a tapeworm hatch in the intestine of the intermediate host, such as cattle or pigs. Once ingested by the intermediate host, the tapeworm larvae develop and migrate to different tissues where they form cysts.
Cats and dogs
Tapeworms are considered indirect parasites because they often require an intermediate host to complete their life cycle. Typically, the adult tapeworm resides in the intestines of a definitive host, such as a mammal, while its larval stages develop in intermediate hosts, like fish or livestock. Transmission occurs when the definitive host consumes the infected intermediate host.
An intermediate host is an organism in which a parasite undergoes part of its life cycle before moving to a definitive host to complete its development and reproduction. Intermediate hosts are essential for the continued survival and transmission of many parasites, providing an environment where specific developmental stages can take place.
Mosquitoes belonging to the Genus Anopheles.Reptile Aves and Mammals are primary host of plasmodium
The deer tick (Ixodes scapularis) is an intermediate host for Borrelia burgdorferi, the bacterium that causes Lyme disease. The bacterium is transmitted to humans through the bite of an infected deer tick.
