1. Manaʻo nui:

(1) Manaʻo: Avian influenza (avian influenza) he maʻi lele lele loa i ka moa i hoʻokumu ʻia e kekahi mau maʻi maʻi serotype pathogenic o nā maʻi maʻi maʻi ʻano A.

Nā hōʻailona maʻi: pilikia ka hanu ʻana, hoʻemi ʻia ka hua manu, ka hemorrhage serosal i loko o nā kino a puni ke kino, a me ka nui o ka make.

(2) Nā hiʻohiʻona etiological

Wahi a nā antigenicity ʻokoʻa: ua māhele ʻia i 3 serotypes: A, B, a me C. Hiki i ke ʻano A ke hoʻopili i nā ʻano holoholona like ʻole, a no ka maʻi maʻi manu ke ʻano A.

Ua māhele ʻia ʻo HA i nā ʻano 1-16, a ua māhele ʻia ʻo NA i nā ʻano 1-10.ʻAʻohe pale keʻa ma waena o HA a me NA.

No ka hoʻokaʻawale ʻana ma waena o ka maʻi manu a me ka maʻi Newcastle moa, hiki i ka maʻi maʻi avian influenza ke hoʻohui i loko o ke koko ʻulaʻula o nā lio a me nā hipa, akā ʻaʻole hiki i ka moa Newcastle maʻi.

(3) Laha ʻana o nā maʻi maʻi

Hiki i nā ma'i ma'i 'avian influenza ke ulu i loko o nā embryos moa, no laila hiki ke ho'oka'awale 'ia nā ma'i ma'i e ka inoculation allantoic o nā embryos moa 9-11 mau lā.

(4) Kūʻē

Pilikia nā maʻi maʻi influenza i ka wela

56℃~30 minuke

kiʻekiʻe wela 60 ℃ ~ 10 minuke Nalo o ka hana

65 ~ 70 ℃, mau minuke

-10 ℃ ~ ola no kekahi mau mahina a ʻoi aku ma mua o hoʻokahi makahiki

-70 ℃ ~ mālama i ka infectivity no ka manawa lōʻihi

Haʻahaʻa wela (glycerin pale）4 ℃ ~ 30 a 50 mau lā (i nā feces)

20 ℃ ~ 7 lā (i ka feces), 18 lā (i ka hulu)

Hiki ke ola ka ʻiʻo moa a me ka iwi iwi no 10 mahina.

Inactivation: formaldehyde, halogen, peracetic acid, iodine, etc.

2. Nā hiʻohiʻona epidemiological

(1) Nā holoholona hiki ke pilikia

ʻO Turkey, ka moa, ka ʻiʻo, ka geese a me nā ʻano moa ʻē aʻe i maʻi pinepine ʻia ma ke kaiapuni kūlohelohe (H9N2)

(2) Puna o ka ma'i

Hiki i nā manu maʻi a me nā moa hoʻōla ke hoʻohaumia i nā mea hana, hānai, wai inu, a me nā mea ʻē aʻe ma o ka excrement, secretions, etc.

(3) Mahele o ka hanana

Hoʻouna ʻia ka subtype H5N1 ma o ka hoʻopili ʻana.Hoʻomaka ka maʻi i kekahi manawa ma ka hale moa, a laila laha i nā manu pili i nā lā 1-3, a hoʻopilikia i ka ʻohana holoʻokoʻa i nā lā 5-7.ʻO ka nui o ka make ʻana o nā moa non-immune i nā lā 5-7 he kiʻekiʻe e like me 90% ~ 100%
