Kitajska profesorica Li Lanjuan in njeni kolegi z univerze v provinci Zhejiang so prou\u010devali vzorce virusa, ki so jih odvzeli 11 bolnikom s covidom-19 v bolni\u0161nici v mestu Hangzhou. Odkrili so 33 razli\u010dnih mutacij, od tega 19 novih.<\/p>\n

“Sars-cov-2 je naredil tak\u0161ne mutacije, ki lahko bistveno spremenijo njegovo patogenost,” so zapisali v znanstvenem \u010dlanku, objavljenem v nedeljo na spletni strani medRxiv.org. \u0160tudije sicer znanstveniki, ki niso sodelovali pri njej, \u0161e niso pregledali.<\/p>\n

Najbolj smrtonosne mutacije, ki so jih na\u0161li pri bolnikih v Hangzhouu, so na\u0161li tudi pri ve\u010dini bolnikov po Evropi. Manj smrtonosni sevi pa so prevladovali v delih ZDA, kot je zvezna dr\u017eava Washington, so ugotovili kitajski znanstveniki po poro\u010danju \u010dasnika South China Morning Post.<\/p>\n

Poleg tega so preu\u010dili tudi, kolik\u0161no koli\u010dino virusa dolo\u010den sev proizvede. To so storili tako, da so celico oku\u017eili z virusom. Ugotovili so, da najbolj smrtonosni sevi ustvarijo tudi do 270-krat toliko virusa kot najmilej\u0161i. Ugotovili so, da “ve\u010dja koli\u010dina virusa vodi v ve\u010dji dele\u017e odmrlih celic”.<\/p>\n

Rezultati njihove \u0161tudije ka\u017eejo, da je raznolikost sevov novega koronavirusa “\u0161e vedno mo\u010dno podcenjena”, so poudarili.<\/p>\n

Ob tem so opozorili, da je treba to pove\u010devanje \u0161tevila mutacij upo\u0161tevati tudi pri razvoju cepiva oziroma zdravila.<\/p>\n

Po navedbah Kitajskega nacionalnega centra za bioinformatiko so sicer znanstveniki po svetu preu\u010dili \u017ee ve\u010d kot 10.000 sevov, ki so vsebovali ve\u010d kot 4300 mutacij novega koronavirusa, poro\u010da South China Morning Post.<\/p>\n","protected":false},"excerpt":{"rendered":"
