100CM Mini Igitsina Cyabakuze

Umutwaro urenze urugero

Delta ntabwo yandura gusa kurenza SARS-CoV-2 zabanjirije iyi, irashobora kandi gutera indwara zikomeye. Eric Topol, avuga ati: “Abantu banduye Delta variant barikubye inshuro 1.000 umubare w’udukoko twa virusi (abahanga bita“ umutwaro wa virusi ”) mu mazuru yabo ugereranije n’abanduye ubundi bwoko,“ ibyo bikaba ari ubwiyongere bukabije. ” washinze akaba n'umuyobozi w'ikigo gishinzwe ubushakashatsi bw’ubuhinduzi bwa Scripps, utagize uruhare muri ubu bushakashatsi.

Impamvu imwe yabyo nuko Delta ihinduka yigana vuba mumazuru. Ubushakashatsi, butarasuzumwa n’urungano bwerekanye ko variant ya Delta yatwaye impuzandengo yiminsi ine kugirango igere kurwego rushobora kugaragara nyuma yo guhura numurwayi, ugereranije niminsi itandatu ya virusi yambere ya Wuhan. Igipupe cyigitsina gabo

Ndetse na nyuma yo gukingirwa, ubwandu bwa Delta bwatanze virusi inshuro 10 kurenza virusi zitari Delta. Mubyukuri ubushakashatsi bwinshi buherutse, ntanumwe murungano rwasuzumwe kugeza ubu, byerekana ko abantu bakingiwe bitwaje umutwaro wa virusi nkuwatakingiwe. Ati: "Turimo kubona indwara kandi tubona umubare munini w'abantu banduye indwara imwe, biteye impungenge. Bisobanura ko virusi yandura cyane kandi ko ishobora kwirinda… ubudahangarwa buterwa n'inkingo, ”ibi bikaba byavuzwe na Ravindra Gupta, inzobere mu binyabuzima muri kaminuza ya Cambridge, wayoboye ubushakashatsi butarasuzumwa.

Delta kandi ni nziza mu gusenya ingirabuzimafatizo kubera ihinduka ry’imiterere ya 681 ya poroteyine ya spike, ikaba yihuta cyane mu zindi mpinduka ku isi kandi ikekwa ko ihindura umukino ubwihindurize. Ihinduka rya P681R ryorohereza Delta hamwe na Kappa ijyanye nayo gutera selile yakira ihuza selile zanduye muburyo bwitwa syncytium, nuburyo bwo kwihutisha kwandura. Syncytia nayo ikorwa nizindi virusi nka VIH. Kei Sato, inzobere mu bijyanye na virusi muri kaminuza ya Tokiyo, mu Buyapani yabisobanuye agira ati: "Twasanze mu bushakashatsi bw’umuco w’akagari ko variant ya Delta yerekana synctia nini ugereranije na SARS-CoV-2".

Ubwoko bwa Delta nabwo bwahinduye ihinduka ryinshi muri poroteyine ya spike isa nkaho itezimbere ubushobozi bwa virusi yo guhuza reseptor ya ACE2 no kwirinda igisubizo cya imimune.
