IMatenda a Chuma

Makhalidwe a etiological:

1. Makhalidwe ndi magulu

Vissista ya matenda osokoneza bongo amakhala m'banja la RNA yolumikizidwa kawiri komanso mtundu wolumikizidwa kwambiri wa RNA. Ili ndi serotypes awiri, ndiye Serotype i (vuto lochokera ku nkhuku) ndi serotype ii (stracype-strain). . Pakati pawo, kuzikakuza kwa serotype ndimasokonekera kumasiyana kwambiri.

2. Virus Rulinjeration

Vutoli limatha kukula ndikupanganso mazira a nkhuku. Idzapha nkhuku masiku 3-5 atayamba kulowa mu chorioallantioc membrane. Zidzapangitsa Edema konsekonse kwa mazira a nkhuku, kusokonezeka ndi zowoneka ngati magazi m'mutu ndi zala zakumiyendo, komanso necrosis ya chiwindi.

3. Kukaniza

Kachilomboka kamakhala wogwirizana kwambiri, wokhazikika, wosagwirizana ndi kuzizira komanso kuwononga, ndipo sagwirizana ndi trypsin, chloroform, ndi etheroform. Zimalekerera mwamphamvu kuti moto ukhalepo ndi ma 56 ° C kwa maola 5 ndi 60 ° C kwa mphindi 30; Vutoli limatha kukhala ndi nkhuku zoipitsidwa masiku 100. Vutoli limachita chidwi ndi kuphera tizilombo toyambitsa matenda monga Peracekin acid, sodium hypochlorite, kupaka ufa ndi ufa wokonzekera ufa ndi chizindikiritso chokhazikika pamatenda, ndipo kachilombo kakutha nthawi yochepa.

4. Hemogglution

Kachilomboka siyitha kubereka magazi ofiira a nkhuku ndi nyama zina zambiri.
