Qhov sib txawv tseem ceeb ntawm L thiab S tus mob coronavirus yog L tus kab mob ua rau pom 'CT' haplotype muaj codon ntawm Leucine ntawm T28, 144 thaum S coronavirus nthuav tawm 'TC' haplotype muaj codon ntawm Serine ntawm C28, 144.
Severe Acute Respiratory Syndrome Coronavirus 2 or SARS-CoV-2 is the causative agent of coronavirus disease – COVID 19. Tus kab mob no twb hu ua 2019 novel coronavirus. Tus kab mob no muaj feem cuam tshuam nrog tus kabmob coronavirus uas muaj feem cuam tshuam rau tus kabmob SARS xyoo 2003. Yog li, tus kabmob tshiab no muaj npe raws li kev sib raug zoo nrog SARS-CoV-1. COVID 19 yog kab mob ua pa uas kis tau los ntawm cov tee dej thiab kev sib cuag ntawm lub cev. Cov tsos mob feem ntau ntawm COVID 19 yog kub taub hau, hnoos qhuav, nkees thiab ua tsis taus pa.
Cov kws tshawb fawb hauv Suav teb tau pom ob hom kab mob SARS-CoV-2 uas tau ncig ntawm tib neeg. Lawv yog hom "L" thiab "S". Ob hom kab no zoo ib yam li ib leeg. L kab yog qhov loj (kwv yees li 70%) thaum S yog tus me (kwv yees li 30%). Ob leeg L thiab S kab muaj kev sib txuas ua tiav ntawm ob SNPs nyob ntawm qhov chaw 8, 782 thiab 28, 144.
L Coronavirus yog dab tsi?
L coronavirus is one of the two strains of SARS-CoV-2. Nws tau pom tias muaj ntau nyob rau theem pib ntawm COVID 19 tshwm sim hauv Wuhan. L tus kab mob kis tau los ntawm tus kab mob S tus laus. Cov kab mob no hnyav dua thiab muaj lub luag haujlwm rau 70% ntawm COVID 19 kis thoob ntiaj teb.
Figure 01: SARS-CoV-2
L kab qhia ua tiav kev sib txuas ntawm ob SNPs ntawm qhov chaw 8, 782 (orf1ab: T8517C, synonymous) thiab 28, 144 (ORF8: C251T, S84L). Nws nthuav tawm 'CT' haplotype txij li T28, 144 nyob hauv codon ntawm Leucine. Tsis tas li ntawd, L kab mob tau sau ntau dua ntawm cov kev hloov pauv tau ntau dua li S kab.
S Coronavirus yog dab tsi?
S coronavirus is the second lineage of SARS-CoV-2. Nws yog tus laus version. Nws ntseeg tau tias L hom yog muab los ntawm S hom. Tus mob coronavirus suav txog kwv yees li 30% tus neeg mob COVID. S hom kab mob tsis tu ncua kis rau cov neeg mob tshiab vim tias nws tsis tshua hnyav, thiab tib neeg nqa nws ntev dua ua ntej noj tshuaj. Yog li ntawd, nws ua rau muaj kev pheej hmoo ntawm kev sib kis. Zoo ib yam li L kab, S kab qhia pom kev sib txuas ua tiav hauv ob SNPs. Ntxiv mus, nws nthuav tawm "TC" haplotype muaj codon ntawm Serine hauv C28, 144.
Dab tsi yog qhov Zoo sib xws ntawm L thiab S Coronavirus?
- SARS-CoV-2 tau hloov mus ua ob hom kab loj hu ua "L" thiab "S" hom.
- Kev sib piv tag nrho-genome ntxiv kom paub meej tias kev sib cais ntawm L thiab S kab
- Cov kab mob no qhia tias tus kab mob hloov pauv.
- Ob leeg L thiab S tus mob coronaviruses qhia txog kev sib txuas ua tiav hauv SNPs ntawm qhov chaw 8, 782 (orf1ab: T8517C, lus hais) thiab 28, 144 (ORF8: C251T, S84L).
- Ob kab kab yuav muaj tus nqi sib txawv hauv kev sib kis lossis rov ua dua.
Qhov txawv ntawm L thiab S Coronavirus yog dab tsi?
L thiab S coronaviruses yog ob hom SARS-CoV-2. L coronavirus yog hom kab mob uas muaj ntau dua, uas yog ib qho ntawm ob hom kab mob SARS-CoV-2. S Coronavirus yog ib hom kab mob SARS-CoV-2 tsawg dua. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm L thiab S coronavirus. L tus mob coronavirus yog lub luag haujlwm rau kwv yees li 70% tus neeg mob thaum S coronavirus yog lub luag haujlwm txog li 30% tus neeg mob.
Ntxiv mus, lwm qhov sib txawv ntawm L thiab S tus mob coronavirus yog L kab mob nthuav tawm 'CT' haplotype thaum S kab nthuav tawm 'TC' haplotype.
Cov hauv qab no infographic tabulates ntau qhov sib txawv ntawm L thiab S coronavirus.
Summary – L vs S Coronavirus
L and S is two strains of SARS-CoV-2. Lawv zoo ib yam li ib leeg. Tab sis, "L" tus mob coronavirus muaj ntau dua thiab muaj lub luag haujlwm rau ntau dua 70% ntawm cov neeg mob thaum "S" coronavirus yog lub luag haujlwm rau kwv yees li 30% ntawm cov neeg mob. Tsis tas li ntawd, L lineage nthuav tawm 'CT' haplotype thaum S lineage nthuav tawm 'TC' haplotype. S lineage yog evolutionary ntau ntsig txog tus tsiaj coronaviruses. L kab mob, ntawm qhov tod tes, tau sau ntau ntau ntawm cov kev hloov pauv tau ntau dua li S kab. Yog li, qhov no qhia txog qhov sib txawv ntawm L thiab S coronavirus.
