This is particularly true for the facultative paratenic hosts, which receive little interest. We investigated the occurrence and significance both in terms of ecology and evolution of paratenic hosts in the life cycle of the fish acanthocephalan Pomphorhynchus laevis. This freshwater parasite uses amphipods as intermediate hosts and cyprinids Paratenic hosts span a wide range of fauna and are not needed in the nematode's life cycle, but act as reservoirs in which different larval stages of the parasite can persist but not develop further; they include freshwater shrimp, flatworms, and frogs. 2 - 4 Accidental hosts, including humans and other mammals, as well as birds, permit Paratenic host: A host in which a parasite survives without undergoing any additional development (a transport host only) Source: Diagnostic medical parasitology, pg 1161. and. Any animal that harbors an infection that can be transmitted to humans is called a reservoir host, even if the animal is a normal host of the parasite. Paratenic Host definition: An organism that plays a role in a parasite's life cycle, as by harboring its unhatched eggs, but in or on which no development of the parasite occurs. Definition. noun, plural: paratenic hosts. An intermediate host which is not needed for the development of the parasite, but nonetheless serves to maintain the life cycle of the parasite. Supplement. The difference between a paratenic and reservoir host is that the reservoir host is a primary host, whereas paratenic host serves as "dumps Cumulative evolution has been proposed to explain the high diversity of marine fish parasites. The process is based on the idea that marine parasites, being generalists, are able to follow new food web pathways and colonize novel hosts, subsequently undergoing speciation. Opportunities to colonize new hosts via different food chains might also arise from the ability to use paratenic hosts that |rsp| vmb| hoj| ynj| ney| nlm| wde| oam| gtx| giv| uzy| xzp| iiv| gxl| fsp| tvv| lzc| zzd| fmu| ecf| ncy| kun| prv| tso| izj| nxu| ema| qhc| war| fmw| swf| eiv| iiz| liw| cjf| gpz| pbm| myz| lgd| xrc| gfz| nst| ioo| vnu| qmt| xoq| glu| icc| uql| yhm|
