1. Isishwankathelo:

(1) Ingqikelelo: Umkhuhlane we-Avian (umkhuhlane weentaka) sisifo esosulelayo kakhulu kwiinkukhu esibangelwa ziintlobo ezithile ze-serotype ze-pathogenic zohlobo lwe-virus zomkhuhlane.

Iimpawu zeklinikhi: ubunzima bokuphefumla, ukuncipha kwemveliso yeqanda, ukopha kwe-serosal kumalungu kuwo wonke umzimba, kunye nezinga eliphezulu lokufa.

(2) Iimpawu ze-Etiological

Ngokwe-antigenicity eyahlukileyo: ihlulwe kwii-serotypes ezi-3: A, B, kunye no-C. Uhlobo A lunokosulela iintlobo zezilwanyana, kwaye umkhuhlane weentaka ungowohlobo lwe-A.

I-HA ihlulwe kwiintlobo ze-1-16, kwaye i-NA ihlulwe kwiintlobo ze-1-10.Akukho khuselo olunqamlezayo phakathi kwe-HA kunye ne-NA.

Ukwahlula phakathi kwe-avian influenza kunye nesifo senkukhu iNewcastle, intsholongwane yomkhuhlane we-avian inokukhula kwiiseli ezibomvu zegazi lamahashe kunye neegusha, kodwa isifo senkukhu iNewcastle asinakho.

(3) Ukwanda kweentsholongwane

Iintsholongwane ze-Avian influenza zinokukhula kwiimbumba zenkukhu, ngoko ke iintsholongwane ziyakwazi ukuhlukaniswa kwaye zigqithwe yi-allantoic inoculation ye-9-11-day-day old embryos.

(4) Ukuchasa

Iintsholongwane zoMkhuhlane ziyabuva ubushushu

56℃~30 imizuzu

ubushushu obuphezulu 60℃ ~ 10 imizuzu Ukulahlekelwa ngumsebenzi

65 ~ 70℃, imizuzu emininzi

-10℃ ~ phila iinyanga ezininzi ukuya ngaphezulu konyaka

-70 ℃ ~ igcina ukosuleleka ixesha elide

Ubushushu obuphantsi (ukhuseleko lwe-glycerin）4℃~30 ukuya kwiintsuku ezingama-50 (kwilindle)

Iintsuku ezingama-20℃~7 (kwilindle), iintsuku ezili-18 (kwiintsiba)

Inyama yenkukhu ekhenkcezisiweyo kunye nomongo wethambo zingaphila iinyanga ezili-10.

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

2. Iimpawu ze-Epidemiological

(1) Izilwanyana ezisengozini

IiTurkey, iinkukhu, amadada, amarhanisi kunye nezinye iintlobo zeenkukhu ezidla ngokusuleleka kwindawo yendalo (H9N2)

(2) Umthombo wosulelo

Iintaka ezigulayo kunye neenkukhu ezifunyenweyo zinokungcolisa izixhobo, ukutya, amanzi okusela, njl njl.

(3) Umzekelo weziganeko

I-H5N1 subtype isasazwa ngoqhagamshelwano.Esi sifo siqala ngexesha elinye kwindlu yenkukhu, emva koko sisasazeka kwiintaka ezikufutshane ngeentsuku ezi-1-3, kwaye sichaphazela umhlambi wonke kwiintsuku ezingama-5-7.Izinga lokubhubha kweenkukhu ezingakhuselekanga kwiintsuku ezi-5-7 liphezulu ukuya kuma-90% ~ 100%
