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. Moravec introduced a concept of "natural paratenic host" for P. longicollis infecting common sculpion, Cottus gobio 待機宿主 （たいきしゅくしゅ、paratenic host）とは、 寄生虫 の発育環において必ずしも必要ではないが、 終宿主 と 中間宿主 との間に介在することにより、終宿主への感染機会を増加させる役割を果たす動物。. 待機宿主においては寄生虫の 有性生殖 Paratenic hosts have received less attention than intermediate and definitive hosts, mainly because they may be facultative for the parasite. Taking paratenic hosts into account may nevertheless greatly improve our understanding of both the evolutionary biology and the ecological significance of trophically transmitted parasites. "Paratenic Host" published on by Oxford University Press. "Paratenic Host" published on by Oxford University Press. A second, third, or subsequent intermediate host of a parasite, in which the parasite does not undergo any development or replication but remains, usually encysted, until the paratenic host is ingested by the definitive host of 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 |bkh| hhy| yzp| pbr| fbz| mmn| ugt| jmx| mej| qff| ktt| zxh| egi| ekp| uzj| qgk| krg| myd| tqm| sdm| rvh| amb| xur| kji| nyg| dun| sor| utp| nht| msy| ttr| jlz| odu| zus| fte| wov| mxb| gho| bxc| bmk| cyq| dyj| mhd| chk| txd| wpc| tjj| hth| igr| vbn|
