Nzira yekumisa Omicron ikozvino? Imwe Chete Yasara!

Omicron iri kupararira semoto wesango kwete muUnited States neEurope chete. Nyanzvi dzinonyevera pamusoro pekuvhara kwakakwana kwezvivako zvakakosha, uye dambudziko risina kumboitika chikamu nekuda kwekupararira kusingadzoreki kweOmicron variant, inozivikanwawo seB.1.1.529.

Chokwadi chichangobva kubuda:

Tsvagiridzo ichangopera muna Zvita 31 uye yakaburitswa nature.com inotaura zvinotevera:

Iyo Omicron (B.1.1.529) musiyano weyakaoma acute respiratory syndrome coronavirus 2 (SARS-CoV-2) yakatanga kuzivikanwa muna Mbudzi 2021 kuSouth Africa neBotswana pamwe nemuenzaniso wemufambi kubva kuSouth Africa kuHong. Kong.

Kubva ipapo, B.1.1.529 yaonekwa pasi rose.

Musiyano uyu unoratidzika kunge une utachiona zvakaenzana pane B.1.617.2 (Delta), wakatokonzera zviitiko zve super spreader, uye wakakunda Delta mukati memavhiki akawanda munyika nenzvimbo dzemadhorobha.

B.1.1.529 inobata nhamba isati yamboonekwa yekuchinja mune yayo spike gene uye mishumo yekutanga zvakapa humbowo hwekupukunyuka kwakanyanya kwekudzivirira uye kuderedza kushanda kwejekiseni.

Pano, takaongorora basa resera kubva mukunaya uye rinosungirwa kuita sera kubva mukunaya, mRNA yakabaiwa kaviri, mRNA yakasimudzirwa, convalescent yakabayiwa kaviri, uye convalescent yakawedzera vanhu kurudzi rwemusango, B.1.351 uye B.1.1.529 SARS-CoV-2 yakazvitsaura.

Neutralinging action of sera from convalescent and double vaccine participated was not seen to very low against B.1.1.529 ukuwo neutralizing basa resera kubva kune vanhu vainge vasangana nespike katatu kana kana mana zvakachengetwa, zvisineyi zvakadzikiswa zvakanyanya.

Kusunga kuB.1.1.529 receptor-binding domain (RBD) uye N-terminal domain (NTD) yakaderedzwa mu convalescent kwete vanhu vakabayiwa asi yakanyanya kuchengetwa muvanhu vakabayiwa.

Chinyorwa ichi chakaongororwa nevezera uye chakagamuchirwa kuti chibudiswe muZvisikwa uye chakapihwa nenzira iyi pano semhinduro kudambudziko rehutano hweveruzhinji. Ichi chinyorwa chinogamuchirwa chichaenderera mberi kuburikidza nemaitiro ekugadzirisa kopi uye fomati kusvika pakuburitswa kweshanduro yakapedzwa yerekodhi pa nature.com.

Ndokumbira utarise kuti panogona kunge paine zvikanganiso zviripo muvhezheni iyi, zvinogona kukanganisa zvirimo, uye zvese zvinoramba zviri pamutemo zvinoshanda.

Maererano nechinyorwa chichangobva kubudiswa chakatanga kubudiswa paCNN International Dr. Peter English, nyanzvi yekudzivirira zvirwere zvinotapukira muUK, akadaro mukutaura.

Mushonga wechitatu wejekiseni unovandudza zvakanyanya maitiro ekurwisa utachiona hweOmicron.

Maererano neCNN, Dr. Julian Tang weYunivhesiti yeLeicester, uyo akanga asinawo kubatanidzwa mukudzidza, akatiwo mhinduro dzeT-cell dzakakosha pakudzivirirwa kwenguva refu pazvirwere zvakakomba. 

"Chinonyanya kukosha ndechekuti kuwedzera hutachiona huripo (kungava mushonga wekudzivirira kana kuwanikwa) kunobatsira kudzivirira kubva kuhutachiona / kutapukirwa kune imwe nhanho - pamwe nekusimudzira mhinduro dziripo dzeT-cell - zvese zvichabatsira kutidzivirira kubva kuOmicron. Saka kuwana aya madosi ekuwedzera kwakakosha - kunyanya kana uri mune rimwe remapoka ari munjodzi, "Tang akadaro
