1. Uhlolojikelele:

(1) Umqondo: I-Avian influenza (umkhuhlane wezinyoni) yisifo esithathelwanayo esithathelwanayo kakhulu ezinkukhuni esibangelwa izinhlobo ezithile ze-serotype ze-pathogenic zohlobo lwamagciwane omkhuhlane.

Izimpawu zomtholampilo: ukuphefumula kanzima, ukuncipha kokukhiqizwa kwamaqanda, ukopha kwe-serosal ezithweni zomzimba wonke, kanye nezinga eliphezulu kakhulu lokufa.

(2) Izici ze-Etiological

Ngokusho kwe-antigenicity ehlukene: ihlukaniswe ngama-serotypes angu-3: A, B, no-C. Uhlobo A lungangena ezinhlobonhlobo zezilwane, futhi umkhuhlane wezinyoni ungowohlobo A.

I-HA ihlukaniswe ngezinhlobo ezingu-1-16, futhi i-NA ihlukaniswe ngezinhlobo ezingu-1-10.Akukho ukuvikeleka phakathi kwe-HA ne-NA.

Ukuhlukanisa phakathi komkhuhlane wezinyoni kanye nesifo senkukhu iNewcastle, igciwane le-avian influenza lingakwazi ukunqwabelana kumangqamuzana egazi abomvu ehhashi nezimvu, kodwa isifo senkukhu iNewcastle asikwazi.

(3) Ukwanda kwamagciwane

Amagciwane omkhuhlane wezinyoni angakhula emibungu yezinkukhu, ngakho-ke amagciwane angahlukaniswa futhi adlule ngokufaka i-allantoic inoculation yemibungu yenkukhu enezinsuku eziyi-9-11.

(4) Ukumelana

Amagciwane omkhuhlane azwela ukushisa

56℃~30 imizuzu

izinga lokushisa eliphezulu 60℃~10 imizuzu Ukulahlekelwa umsebenzi

65 ~ 70 ℃, imizuzu embalwa

-10℃~phila izinyanga ezimbalwa kuya ngaphezu konyaka

-70 ℃ ~ igcina ukutheleleka isikhathi eside

Izinga lokushisa eliphansi (ukuvikelwa kwe-glycerin）4℃~30 izinsuku ezingu-50 (endle)

Izinsuku ezingama-20℃~7 (endle), izinsuku eziyi-18 (ezimpapheni)

Inyama yenkukhu eqandisiwe nomnkantsha ingaphila izinyanga eziyishumi.

Ukungasebenzi: i-formaldehyde, i-halogen, i-peracetic acid, i-iodine, njll.

2. Izici ze-Epidemiological

(1) Izilwane ezithintekayo

Ama-turkeys, izinkukhu, amadada, amahansi nezinye izinhlobo zezinkukhu ezivame ukutheleleka endaweni yemvelo (H9N2)

(2) Umthombo wokutheleleka

Izinyoni ezigulayo nezinkukhu ezitholiwe zingangcolisa amathuluzi, ukudla, amanzi okuphuza, njll. ngendle, uketshezi, njll.

(3) Iphethini yezehlakalo

I-H5N1 subtype idluliselwa ngokuthintana.Lesi sifo siqala ngesikhathi esisodwa endlini yezinkukhu, bese sisakazeka ezinyoni eziseduze ezinsukwini ezingu-1-3, futhi sithinta umhlambi wonke ngezinsuku ezingu-5-7.Izinga lokufa kwezinkukhu ezingezona amasosha omzimba ezinsukwini ezi-5-7 liphezulu lifinyelela ku-90%~100%
