Litšobotsi tsa Etiological:

1. Litšobotsi le lihlopha

Kokoana-hloko e tšoaetsanoang ea lefu la cystic ke ea lelapa la kokoana-hloko ea RNA e nang le likarolo tse peli le mofuta oa likokoana-hloko tsa RNA tse nang le likarolo tse peli. E na le li-serotypes tse peli, e leng serotype I (sehlahisoa se tsoang ho khoho) le serotype II (sehlahisoa se tsoang ho turkey). . Har'a bona, virulence ea mefuta ea serotype I e fapana haholo.

2. Ho ata ha vaerase

Kokoana-hloko e ka hola le ho ikatisa maheeng a likhoho. E tla bolaea mahe a mahe a likhoho matsatsi a 3-5 ka mor'a hore e kenngoe ka har'a lera la chorioallantoic. E tla baka edema hohle maheng a likhoho, tšubuhlellano le ho tsoa mali a kang matheba hloohong le menoaneng, le necrosis e mottled ea sebete.

3. Khanyetso

Kokoana-hloko ena e manganga haholo, ha e khone ho khanya, e hanana le serame khafetsa le ho qhibiliha, 'me e hanana le trypsin, chloroform, le ether. E na le mamello e matla ea mocheso 'me e ka phela ho 56°C lihora tse 5 le 60°C metsotso e 30; kokoana-hloko e ka phela matlong a likhoho a nang le tšoaetso ka matsatsi a 100. Kokoana-hloko e na le kutloelo-bohloko ho likokoana-hloko tse kang peracetic acid, sodium hypochlorite, phofo e soeufalitsoeng le litokisetso tsa iodine tse nang le metsoako e tloaelehileng ea ho thibela likokoana-hloko, 'me kokoana-hloko e ka tima ka nako e khutšoanyane.

4. Hemagglutination

Kokoana-hloko ena ha e khone ho bokella lisele tse khubelu tsa mali tsa likhoho le liphoofolo tse ling tse ngata.
