Iisifo se-cyst

Izici ze-Etiological:

1. Izimfanelo kanye nezigaba

I-virus yesifo esithathelwanayo ye-cystic ingeyomndeni we-RNA we-RNA ehlukaniswe kabili engxenyeni ephindwe kabili ebunjiwe kanye nohlobo lwe-RNA we-RNA ehlukaniswe kabili. Inama-serotypes amabili, okungukuthi i-serotype ngi (inform-ethathwe yinkukhu) kanye ne-serotype II (Turkey-asuswe nzima). . Phakathi kwazo, i-virulence ye-serotype ngihlukahlukene kuyehluka kakhulu.

2. I-Virus Proliferation

Igciwane lingakhula futhi liphinde likhiqize imibungu yenkukhu. Kuzobulala imibungu yenkukhu engu-3-5 ezinsukwini ezingama-3-5 ngemuva kokuba ifakwe ulwelwesi lwe-choriolantantoic. Kuzobangela i-Edema yonke imibungu yenkukhu, ukugcwala kanye nokuphuma okufana nokopha ekhanda nasezinzwaneni, kanye ne-necrosis yezibindi.

3. Ukumelana

Leli gciwane limelana kakhulu, lingamelana nokukhanya, limelana nokuphindaphindwa nokuphindwa, futhi lingamelana ne-trypsin, chloroform, ne-ether. Inokubekezelela okuqinile ekushiseni futhi ingaphila ku-56 ° C amahora angama-5 kanye nama-60 ° C imizuzu engama-30; Igciwane lingasinda ezindlini zenkukhu ezingcolile zezinsuku eziyi-100. Leli gciwane liyazwela amagciwane afana ne-acid acid, i-sodium hypochlorite, i-bleaching powder kanye amalungiselelo e-iodine anokugxila kwegciwane elijwayelekile, futhi igciwane lingafakwa ngesikhathi esifushane.

4. Hemaglutination

Leli gciwane alikwazi ukuqaqa amangqamuzana abomvu egazi izinkukhu nezinye izilwane eziningi eziningi.
