Ka taea e ki te rewharewha manu mutate ka meinga he urutā i roto i te tangata?

Kua whakahaere pūtaiao ngā taiwhanga i roto i i whakakitea e kia riro te kaha ki te horapa i te tangata tetahi ki tetahi i raro i te mana o e toru irakētanga ohie o te rewharewha avian.

Otiia e kore e wehi ki te titiro mo te take, me te tiaki koiora: kihai i nga kairangahau huri te huaketo iho (kua kite katoa matou kiriata nui e pā ana ki fakatamaki ki te karo i tenei hapa). I te anga ke, ka āwhina i enei rangahau whakaponohia pūtaiao ki te noho i mua o te huaketo ki te aukati i tona horapa pea.

rewharewha manu pehea mōrearea

Kairangahau riaka hiahia i huaina rewharewha avian A (H7N9). E ai ki WHO, i 2013, pāngia tenei huaketo neke atu i te 900 te iwi. Otiia, i pā te nuinga o ngā take nui ki te iwi e mahi i roto i te heihei mai kore e taea te huaketo ano ki sustainably roto tangata.

I roto i te kino rawa take, kia mutate te huaketo ki te puka e taea te i roto i te tangata, a pea timata ki te horapa rite wildfire. Ko te kupu, pūtaiao i California mahi ki te momo o irakētanga i roto i te genome o H7N9, kia kite i te aha e taea e te āwhina i te huaketo ki te horapa i roto i te tangata.

irakētanga ohie

Scientists mahi ki te pūmua i runga i te mata o te huaketo i huaina hemagglutinin H7. āhei te reira i te huaketo ki te here ki te manaaki i ngā pūtau, ka whakapoke ratou.

kitea ratou e he ahei o irakētanga iti i roto i te toru waikawa amino kitea i runga i te mata o te huaketo e taea ai te reira ki te pai here ki receptors pūtau kitea i runga i ngā pūtau tangata, he mea whakarite ki ngā pūtau avian tenei pūmua.

I roto i te taiwhanga, kua whakaputaina kaipūtaiao te H7 haemagglutinin mutant takitoru me i kitea e pai taea riro ratou i te tunga i runga i te pūtau i roto i te tauira pukorokoro kiko tangata.

E i reira kia he urutā?

ture haumaru ta'ofi te tomokanga o enei irakētanga i roto i enei wheori H7N9, na tohu nga kaituhi o te ako i roto i e kore i hanga e ratou i te huaketo, ka whakamahia anake ona te kongakonga Koló. Irakētanga ki tūturu H7N9 tohu ngā ki nui haere ngā mahi viral e kua rāhuitia tēnei wā (no te mau tumu kitea).

Na ano, ahakoa ki te wehi o enei kitenga? Te āhua, e kore e ano. Fiona Kalli, he mātanga i roto i Immunology romahā i Imperial College London, e ai ta e te tūponotanga o te faaiteraa tukutahi o irakētanga e toru katoa "āhua iti."

"E tauturu i tenei ako tatou ki ake āta whakahaere i te tūponotanga e pā ana ki te rewharewha avian, a ki te faarahi i to tatou mohio o te mea e taui i roto i te huaketo rewharewha avian taea e pea mōrearea," - ka mea ia.
