What is paratenic or transport host?

What is a Paratenic host?

A species that acts as a secondary or subsequent intermediate host for a parasite with a complex life cycle that usually involves two or more species.

What is a transport host?

A transport host is a carrier in which the organism remains alive, but does not develop. An agent of an infectious disease is necessary but not always sufficient to cause a disease or disorder.

What is the purpose of Paratenic?

Paratenic hosts, especially of nematodes, play a major role in spreading many parasite species. The phenomenon of “paratenic parasitism” is illustrated by examples of development of Syngamus trachea and Proteocephalus longicollis.

What is the difference between Paratenic host and reservoir host?

The difference between a paratenic and reservoir host is that the reservoir host is a primary host, whereas paratenic host serves as “dumps” for non-mature stages of a parasite which they can accumulate in high numbers.

What is the difference between host and reservoir?

Definition and terminology

By these definitions, a reservoir is a host that does not experience the symptoms of disease when infected by the pathogen, whereas non-reservoirs show symptoms of the disease.

  • accidental host. a host that shelters an organism which does not usually parasitize that host.
  • incidental host (a.k.a. dead-end host) a host that shelters an organism but is unable to transmit the organism to a different host.
  • primary host (a.k.a. definitive/final host) …
  • reservoir host.

Even though dogs and cats are the definitive host, larvae may also persist or even cause severe disease in a variety of paratenic host species.

What is the meaning of reservoir host?
