Iisifo se-cyst esithathelwanayo

Izici ze-Etiological:

1. Izimfanelo nezigaba

Igciwane elithathelwanayo le-cystic lingelomndeni wegciwane le-RNA elinemigqa ephindwe kabili kanye nohlobo lwegciwane le-RNA elinemigqa ephindwe kabili.Inezinhlobo ezimbili ze-serotypes, okuyi-serotype I (uhlobo olutholakala kwinkukhu) kanye ne-serotype II (uhlobo olususelwa ku-turkey)..Phakathi kwazo, i-virulence yezinhlobo ze-serotype I ziyahlukahluka kakhulu.

2. Ukusabalala kwegciwane

Igciwane lingakhula futhi liphindaphindeke emibungu yenkukhu.Izobulala imibungu yenkukhu ezinsukwini ezi-3-5 ngemuva kokujova kulwelwesi lwe-chorioallantoic.Izodala ukuqubuka kuyo yonke imibungu yenkukhu, ukuminyana nokopha okufana namachashaza ekhanda nasezinzwaneni, kanye ne-necrosis enamabala esibindini.

3. Ukumelana

Leli gciwane liyamelana kakhulu, alikwazi ukumelana nokukhanya, limelana nokubanda okuphindaphindiwe nokuncibilika, futhi liyamelana ne-trypsin, i-chloroform, ne-ether.Iyakwazi ukubekezelela ukushisa futhi ingaphila ku-56°C amahora ama-5 kanye no-60°C imizuzu engu-30;igciwane lingaphila ezindlini zezinkukhu ezinegciwane izinsuku eziyikhulu.Leli gciwane liyazwela emagciwaneni anjenge-peracetic acid, i-sodium hypochlorite, i-bleaching powder kanye namalungiselelo e-iodine anomthamo ovamile wokubulala amagciwane, futhi igciwane lingenziwa lingasebenzi ngesikhathi esifushane.

4. I-Hemagglutination

Igciwane alikwazi ukuhlanganisa amangqamuzana abomvu egazi ezinkukhu nezinye izilwane eziningi.
