Hoʻoponopono ka lāʻau lapaʻau i kēia mau lā i nā maʻi parasite, nā ʻākena causative e komo i loko o nā ʻōnaehana kanaka. ʻO kekahi o nā kumu no ka hoʻokumu ʻana i nā pathologies ka hoʻohana ʻana i nā iʻa maikaʻi ʻole i kuke ʻia.

Pili ke kumu ʻelua inā ʻaʻole pili ka hoʻomākaukau ʻana o ka iʻa i nā ʻenehana kūpono. ʻO nā mea aloha iʻa iʻa i lilo i mau mea maʻi pinepine me ka hopena o nā maʻi parasite.

ʻO kahi helminth koʻikoʻi ma waena o nā trematodes metacercarium... Aia ia i loko o ka iʻa, pāpaʻi, a pili pono i ka hui o flatworms. Hiki i nā Helminths o kēia ʻano ke komo i loko o ka iʻa.

ʻO ka weliweli loa ke komo i nā maka a me ka lolo o ka iʻa. Eia kekahi, noho nā ilo ma loko o nā aquarium. Hele lākou mai laila mai nā waihona wai, neʻe pū me nā nīʻau. ʻAʻole ia he mea maʻamau ke komo ʻana o ka iʻa i kahi noho ʻoluʻolu me ka meaʻai a hoʻouka kaua i ka nohona, nā meaola olakino.

Nā hiʻohiʻona a me nā wahi noho o metacercaria

ʻO Opisthorchis metacercariae Aia i loko o kaʻiʻo muscle o ke kauoha carp. No ka cecariae (larvae), he iʻa waena ka iʻa. I loko o ia mea, ulu ka cecariae i metacercarium. ʻAʻole hiki i nā Parasite ke hoʻoili ʻia mai kekahi i kekahi iʻa ʻē aʻe, he ʻelala.

Hiki ke lilo i maʻi me nā helminths e nā mākua makua makua wale nō. Ua hōʻoia nā ʻepekema ʻo ka wai kolepa loko kolona, ​​minnow, kahawai wai, pulu ma lalo o nā manawa i hāʻawi ʻole iā lākou iho i ka maʻi.

I ka hapanui o nā hihia, aia nā ilo ma nā maka, e hoʻopili ana:

  • maka aniani;
  • kino vitreous;
  • nohona kūloko o nā ʻōmaka.

ʻEhā mau hui e hoʻohui i nā leona he ʻumikumamākolu o nā leona o ka maka a me nā aniani. Weliweli ka Metacercariae no ka mea kūpaʻa lākou i ke kaiapuni. ʻAʻole lākou makaʻu i nā mahana haʻahaʻa.

ʻO Metacercariae i ka iʻa

Wale ma ka hau ʻana i ka huahana i - 40 ° C no 7 mau hola, nalowale nā ​​larvae. Inā paʻahau ma -35 ° C, lilo i nā cecarii ke ola ma hope o 14 mau hola o ke anuanu.

ʻO ka iʻa anuanu ma -28 ° C ma kahi o 32 mau hola e hemo ai i ka parasite. Akā i nā kekelē kiʻekiʻe, hōʻike wikiwiki nā parasites. Ma hope o ke kaʻina hana no ka hoʻokaʻawale ʻana mai ka iʻa, make lākou i 5-10 mau minuke ma + 55 ° C.

Ma ka hoʻomohala ʻana metacercariae o nā trematodes, loaʻa nā hiʻohiʻona:

  • ʻohana hanauna ʻē aʻe;
  • hoʻololi i nā mea nona.

ʻO nā moluska, nā iʻa, nā mea kolo e lilo i mau pūʻali waena waena o nā trematodes. Loaʻa i kēia ʻano helminth kahi mea hoʻokipa hou aʻe. Akā ma 80% o nā hihia, i ka wā o ka hoʻomohala, hiki iā ia ke hana me ka ʻole o ia.

ʻO nā hanauna ʻokoʻa i ka wā o ka hana kope ʻana i nā parasites ʻaʻole wale i nā ilo i hana ʻia, akā i nā larvae hoʻi. Hānau ka larvae i kekahi hanauna hou o cecarii, a laila ulu a lilo i ʻano makua.

Ke ʻano a me ka nohona o metacercaria

ʻOkoʻa ka Metacercariae mai nā helminths ʻē aʻe o kā lākou papa i ko lākou liʻiliʻi liʻiliʻi. Hoʻokomo ʻia ke kino o ka helminth me nā kīʻaha ʻelua:

1. ʻōpū;
2. waha.

Hoʻouka nā ilo i nā membrane mucous o kā lākou mea hoʻokipa, e omo i nā mea momona, a laila e mālama nei i kā lākou hana nui. ʻO ke kīʻaha omo ka hoʻomaka o ka tract digestive. Loaʻa i ka hope o ke kino kahi kahawai no ka hoʻokuʻu ʻana i nā meaʻai i hana ʻia.

Ke komo nei i loko o nā iʻa o ka iʻa, ʻaʻole hoʻonui nā ilo. Ke noho nei i kēia ʻano, ʻaʻohe o lākou manawa kūpono e hānai a ulu ai. Ke kali nei lākou i ka manawa e ʻai ʻia ka iʻa hoʻokipa. I loko o kēia wā holoʻokoʻa, hūnā nā microorganism i loko o ka capsule, i hana ʻia e ka iʻa cartilaginous o ka iʻa.

Mālama ʻo Metarcercariae e hūnā i nā mea ʻona e alakaʻi i ka make o nā lobes lālā. Ua nāwaliwali ka iʻa, aia ma luna o ka wai, no ka mea ʻike lākou i ka lawa ʻole o ka oxygen.

Komo ka iʻa i ka ʻupena a nā lawaiʻa, a i lilo i manuahi o nā manu, ʻīlio, pōpoki. Ma hope o ka ʻai ʻana i kahi iʻa maʻi, hoʻouka ka helminths i ke kino o ka mea hope loa, kahi e alakaʻi pinepine ai i ka hoʻomohala ʻana i kahi pathology me ka inoa. clacorchis metacercaria.

Pā maikaʻi ʻole nā ​​parasites i ka iʻa hoʻokipa. Lilo ia i mea hoʻomaha ʻole, hoʻopili ʻia e nā maʻi bacteria, a hiki i ke kaʻina o ka pala pala. Wahi a nā ʻike helu, ʻo ka make o nā iʻa kāhiko i hoʻopili ʻia e ka metarcercariae he 50% a ʻoi paha.

ʻO ka metacercaria meaʻai

Noho ʻo Metarcercariae i loko o nā vertebrates, pili paʻa me nā mea omo, he ʻōpū. ʻAi ʻo Microorganism i nā aʻa o kā lākou mea hoʻokipa a i ʻole nā ​​ʻike o kāna ʻōpū. Inā komo nā ilo i loko o nā gills o kahi iʻa, ʻaʻole ʻai iki lākou. ʻO kā lākou hana e hoʻopili i ka iʻa me kahi maʻi no ka luku ʻia ʻana e kāna mea hoʻokipa hope loa.

Hoʻohua a me ke ola o ka metacercaria

I loko o kahi iʻa ola metacercariae o opisthorchiasis he wā lōʻihi. ʻO ko lākou awelika hiki ke pae ʻia mai 5 a 8 mau makahiki. Ke komo nei i loko o ke kino o ka hoʻokipa hope loa, ʻike ʻia nā parasites e ke ʻano piha ʻana, kahi e lilo ai ka ilo i 0.2 a 1.3 centimetres ka lōʻihi, a i 0.4 kenimika ākea.

Inā hana kekahi kanaka ma ke ʻano he mea nona, noho nā ʻenuhe i loko o kāna gallbladder, duct pancreatic, dile dile o ke ake. Hoʻokumu ʻia, metacercariae kau i nā hua, i komo i ke kaiapuni me nā fitter excreted.

Eia hou, ke ulu nei ka parasite i nā pae, e komo i ka mollusk i loko o ka mea hoʻokipa waena. Ma hope o ke komo ʻana i loko o ka iʻa carp, kahi hou o nā helminths. Loaʻa i ka parasite mākua kahi cyst oval a pōʻai paha, ma loko kahi e koe ai ka larva.

Inā metimercariae i untimely kuhikuhi, a me ka hewa hoʻolilo ia i loko o ke kino o ka hope nona, hoʻonāukiuki kekahi mau maʻi. ʻAʻole ia e nalo mai ke kino me ka ʻole o ke kōkua o ka hoʻoponopono a hiki i ka 10-20 mau makahiki.
