Inkukhu yebronchitis eyosulelayo

1. Iimpawu ze-Etiological

1. Iimpawu kunye nokuhlelwa

Intsholongwane yebronchitis eyosulelayo yeyosapho i-Coronaviridae kwaye uhlobo lwe-coronavirus yeyentsholongwane ye-bronchitis eyosulelayo yenkukhu.

2. Serotype

Ekubeni i-S1 gene ilungele ukuguqulwa ngokuguqulwa, ukufakwa, ukucinywa, kunye nokudibanisa i-gene ukuvelisa i-serotypes entsha yentsholongwane, i-virus ye-bronchitis echaphazelekayo iguquguquka ngokukhawuleza kwaye ine-serotypes ezininzi. Kukho iiserotypes ezahlukeneyo ezingama-27, iintsholongwane eziqhelekileyo ziquka iMisa, iConn, iGrey, njl.

3. Ukwanda

Intsholongwane ikhula kwi-allantois ye-10-11 yeentsuku zenkukhu, kwaye ukuphuhliswa komzimba we-embryo kuvaliwe, intloko igobile phantsi kwesisu, iintsiba zifutshane, zinzima, zomile, i-amniotic fluid incinci, kwaye uphuhliso lomzimba we-embryo luvaliwe, lwenza "i-embryo encinci".

4. Ukuchasa

Intsholongwane ayinakuxhathisa ngamandla kwihlabathi langaphandle kwaye iyakufa xa ishushu kwi-56 ° C / imizuzu eyi-15. Nangona kunjalo, inokuphila ixesha elide kumaqondo aphantsi. Umzekelo, inokuphila iminyaka esi-7 kwi--20°C kunye ne-17 iminyaka kwi--30°C. Izibulali-ntsholongwane ezisetyenziswa ngokuqhelekileyo zinovelwano kule ntsholongwane.
