Iisifo se-cyst esosulelayo

Iimpawu ze-Etiological:

1. Iimpawu kunye nokuhlelwa

Intsholongwane yesifo se-cystic esosulelayo yeyosapho lwentsholongwane ye-RNA enamacala amabini aphindwe kabini kunye ne-RNA virus ephindwe kabini. Ine-serotypes ezimbini, ezizezi, i-serotype I (i-chicken-derived strain) kunye ne-serotype II (i-turkey-derived strain). . Phakathi kwabo, i-virulence ye-serotype I strains iyahluka kakhulu.

2. Ukwanda kwentsholongwane

Intsholongwane inokukhula kwaye iphindaphindeke kwiimbumba zenkukhu. Iza kubulala iimbumba zenkukhu emva kweentsuku ezi-3-5 emva kokuba zifakwe kwi-membrane ye-chorioallantoic. Kuya kubangela ukudumba kuzo zonke iimbumba zenkukhu, ukuxinana kunye nokopha okufana namachaphaza entloko nasezinzwaneni, kunye ne-necrosis enamabala esibindini.

3. Ukuchasa

Intsholongwane iyaxhathisa kakhulu, ayinyangeki ekukhanyeni, ayixhathisi ngokuphindaphindiweyo ukukhenkceka kunye nokunyibilika, kwaye iyaxhathisa kwi-trypsin, i-chloroform, kunye ne-ether. Inokunyamezela ngamandla ubushushu kwaye inokuphila kwi-56 ° C kwiiyure ze-5 kunye ne-60 ° C imizuzu engama-30; intsholongwane ingaphila kwizindlu zeenkukhu ezisulelekileyo kangangeentsuku ezili-100. Intsholongwane ivakalelwa kwii-disinfectants ezifana ne-peracetic acid, i-sodium hypochlorite, i-bleaching powder kunye namalungiselelo e-iodine kunye noxinzelelo oluqhelekileyo lwe-disinfection, kwaye intsholongwane inokuthi ingasebenzi ngexesha elifutshane.

4. Hemagglutination

Le ntsholongwane ayinako ukudibanisa iiseli ezibomvu zegazi leenkuku nezinye izilwanyana ezininzi.
