1. Manaʻo nui:
(1) Manaʻo: Avian influenza (avian influenza) he maʻi lele lele loa i loko o ka moa i hoʻokumu ʻia e kekahi mau maʻi maʻi serotype pathogenic o nā maʻi maʻi influenza ʻano A.
Nā hōʻailona maʻi: pilikia ka hanu ʻana, hoʻemi ʻia ka hua manu, ka hemorrhage serosal i loko o ke kino holoʻokoʻa, 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 avian a me ka moa Newcastle maʻi, 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 o nā moa non-immune i nā lā 5-7 he kiʻekiʻe e like me 90% ~ 100%
