CHKBiotech idapanga bwino zida zodziwira mitundu yatsopano yama coronavirus

New Coronavirus Variant Strain 501Y-V2 yaku South Africa
Pa Disembala 18th, 2020, South Africa idapeza 501Y-V2 mutant ya coronavirus yatsopano. Tsopano chosintha ku South Africa chafalikira kumayiko opitilira 20. Kafukufuku wasonyeza kuti pamwamba pa New Corona-virus Mutants itha kunyamula zosintha zina za New Coronavirus za K417N / T, E484K ndi N501Y zomwe zingachepetse mphamvu yoteteza katemera wopangidwa ndi plasma. Komabe, poyerekeza ndi genome yofotokozera Wuh01 (ndondomeko yotsatizana MN908947), 501Y.V2 ya South African mutant genome sequence ili ndi ma 23 nucleotide mitundu. Ili ndi kusintha komweko kwa N501Y monga Britain mutant B.1.1.7 sub-type, komabe kuli kusintha kwamasamba m'malo awiri ofunikira a E484K ndi K417N a S protein omwe angakhudze kuthekera kwa kachilombo koyambitsa matendawa.

New Coronavirus ndi RNA Virus yokhayokha, yomwe ma genome amasintha pafupipafupi. Kuzindikira kwamtundu umodzi kumatha kubweretsa kusapezeka kwa zitsanzo zomwe zili ndi kuchuluka kwamavuto ochepa komanso mitundu yama virus yosinthidwa. Mulingo wofufuzidwanso mwawokha pazomwe zikuwunikira, ukhoza kufikira 10%, zomwe zitha kuwonjezera kuchuluka kwa ntchito ndikuchulukitsa nthawi yodziwitsidwa. Kuzindikira kwamitundu ingapo ndikuwunikirana zotsatira za chandamale chilichonse kumatha kukulitsa kuchuluka kwakudziwitsidwa ndikuthandizira kuzindikira koyambirira.

Coronavirus Mutant B.1.1.7 yatsopano yaku Britain
Pa Disembala 26th, 2020, pepala loyamba la sayansi la B.1.1.7 Strain lidasindikizidwa pa intaneti. Institute of Hygiene University of London UK and Tropical Diseases, idatsimikiza kuti B.1.1.7 Strain imatha kufalikira kuposa mitundu ina, yomwe inali yoposa 56% (95% CI 50-74%). Chifukwa vuto latsopanoli lili ndi mphamvu zowonekera, kwakhala kovuta kuwongolera COVID-19. Tsiku lotsatira, University of Birmingham ku United Kingdom idalemba nkhani yokhudza MedRxiv. Kafukufukuyu adawona kuti kuchuluka kwa ma virus amtundu wa ORF1ab ndi N mwa odwala omwe ali ndi vuto la B.1.1.7 mutant (S-gene kusiya) adakulirakulira; chodabwitsa ichi chinali kuyang'aniridwa mwa anthu. Nkhaniyi ikufotokoza kuti odwala omwe ali ndi kachilombo ka B.1.1.7 ku Britain ali ndi chiwopsezo chachikulu kwambiri cha ma virus, chifukwa chake kusintha kumeneku kumathanso kukhala kwachisawawa.

Chidziwitso cha Mitundu Yatsopano ya Coronavirus
Chuangkun Biotech Inc.yakhazikitsa bwino zida zodziwika za B.1.1.7 ndi 501Y-V2 mitundu yatsopano ya coronavirus.

Ubwino wa malonda awa: Kuzindikira kwakukulu, kuzindikira kwakanthawi kofananira kwa zolinga 4, zokutira malo osintha kwambiri a B.1.1.7 kupsinjika kosinthika ndi 501Y.V2 mavuto aku South Africa. Chida ichi chimatha kudziwa nthawi yomweyo N501Y, HV69-70del, E484K masinthidwe ndi mtundu watsopano wa coronavirus S; Kuyesa mwachangu: zimangotenga ola limodzi mphindi 30 kuchokera pamayeso osonkhanitsira kuti zitheke.
