Influenza A/B Antigen

Fuluwenza, wotchedwa chimfine, ndi wa Orthomyxoviridae ndipo ndi segmented negative-strand RNA virus.Malinga ndi kusiyana kwa antigenicity wa nucleocapsid mapuloteni (NP) ndi masanjidwewo mapuloteni (M), fuluwenza mavairasi anawagawa mitundu itatu: AB, ndi C. Fuluwenza mavairasi anapeza m'zaka zaposachedwapa.wzodwala zitha kugawidwa ngati D.Pakati pawo, mtundu A ndi mtundu B ndi tizilombo toyambitsa matenda a chimfine, omwe ali ndi makhalidwe a kufalikira kwakukulu ndi matenda amphamvu.Mawonetseredwe azachipatala makamaka ndi zizindikiro za poizoni monga kutentha thupi, kutopa, kupweteka mutu, chifuwa, ndi kupweteka kwa minofu, pamene zizindikiro za kupuma zimakhala zochepa.Zingayambitse matenda aakulu kwa ana, okalamba ndi anthu omwe ali ndi chitetezo chochepa cha chitetezo cha mthupi, chomwe chimaika moyo pachiswe.Kachilombo ka Influenza A kamakhala ndi masinthidwe ambiri komanso kufalikira kwamphamvu, ndipo miliri ingapo yapadziko lonse lapansi imakhudzana ndi izi.Malingana ndi kusiyana kwake kwa antigenic, imagawidwa mu 16 hemagglutinin (HA) subtypes ndi 9 neuroamines (NA) subtypes.Kusintha kwa kachirombo ka fuluwenza B ndikotsika kuposa kwa chimfine A, komabe kumatha kuyambitsa miliri yaying'ono komanso miliri.
