1. Incamake:

.

Ibimenyetso bya Clinical: ingorane zo guhumeka, kugabanuka k'umusaruro w'amagi, kuva amaraso ya serosal mu ngingo z'umubiri wose, ndetse n'impfu nyinshi cyane.

(2) Ibiranga Etiologiya

Ukurikije antigenicite itandukanye: igabanijwemo serotypes 3: A, B, na C. Ubwoko A bushobora kwanduza inyamaswa zitandukanye, kandi ibicurane by’inyoni ni ubwoko bwa A.

HA igabanijwe mubwoko 1-16, NA igabanyijemo ubwoko 1-10. Nta kurinda kwambuka hagati ya HA na NA.

Gutandukanya ibicurane by'ibiguruka n'inkoko Indwara ya Newcastle, virusi y'ibicurane by'ibiguruka irashobora gukwirakwira mu maraso atukura y'amafarasi n'intama, ariko indwara y'inkoko Newcastle ntishobora.

(3) Ikwirakwizwa rya virusi

Virusi y'ibicurane by'ibiguruka irashobora gukura mu nsoro z'inkoko, bityo virusi zirashobora kwigunga no kwanduzwa na allantoic gutera intanga z'inkoko zimaze iminsi 9-11.

(4) Kurwanya

Virusi y'ibicurane yumva ubushyuhe

56 ℃ ~ iminota 30

ubushyuhe bwo hejuru 60 ℃ ~ iminota 10 Gutakaza ibikorwa

65 ~ 70 ℃, iminota myinshi

-10 ℃ ~ kubaho amezi menshi kugeza kurenza umwaka

-70 ℃ ~ ikomeza kwandura igihe kirekire

Ubushyuhe buke (kurinda glycerine）4 ℃ ~ 30 kugeza 50 (mumase)

20 ℃ ~ iminsi 7 (mumase), iminsi 18 (mumababa)

Inyama z'inkoko zikonje hamwe n'amagufwa arashobora kubaho amezi 10.

Kudakora: formaldehyde, halogene, aside peracetike, iyode, nibindi.

2. Ibiranga Epidemiologiya

(1) Ibikoko byoroshye

Turukiya, inkoko, inkongoro, ingagi n’andi moko y’inkoko akunze kwandura ibidukikije (H9N2)

(2) Inkomoko yanduye

Inyoni zirwaye hamwe n’inkoko zagaruwe zirashobora kwanduza ibikoresho, kugaburira, amazi yo kunywa, nibindi binyuze mumyanda, gusohora, nibindi.

(3) Icyitegererezo

Ubwoko bwa H5N1 bwoherezwa binyuze mumikoranire. Indwara itangirira ahantu hamwe munzu yinkoko, hanyuma ikwirakwira ku nyoni zegeranye muminsi 1-3, kandi yanduza umukumbi wose muminsi 5-7. Umubare w'impfu z'inkoko zidafite ubudahangarwa mu minsi 5-7 ziri hejuru ya 90% ~ 100%
