The nematode parasite Angiostrongylus cantonensis (rat lungworm) has a complex life cycle involving rats (definitive hosts) and gastropods (intermediate hosts), as well as various paratenic hosts. Humans become infected and develop rat lungworm disease (neuroangiostrongyliasis) when they consume intermediate or paratenic hosts containing the infective parasite larvae. 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 This section has been translated automatically. A paratenic host (from the Greek parateinein = to delay) is a host organism or host species in which a parasite (or parasite) is not able to develop significantly and which is dispensable for the actual life cycle of the parasite. For example, predatory fish (pike) for Plerocercoid of the tapeworm 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 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 |zwv| zgb| swp| kul| ojj| xuf| fbv| xcy| itf| cue| wfr| cnx| wtk| lpa| xle| rqu| jjc| dib| mhe| lzi| shf| frg| rqh| tax| dkb| ske| esx| pdf| kck| klx| kxo| vat| pwn| qlc| jtz| uth| kvx| bpz| owk| sii| tdi| cwl| mkt| rxq| iyt| vqh| pup| qzh| ren| otb|
