Ka ho ntaramane nonyana ho mutate le ho etsa hore e le seoa har'a batho?

Bo-rasaense ba a khanna liteko laboratori eo o ile a bontša hore tlas'a tšusumetso ea liphetoho liphatseng tsa lefutso tse tharo e bonolo ya ntaramane avian a ka fumana matla a ho jala ho tloha motho a le mong ho e 'ngoe.

Empa u se ke ua tšaba ho batla sutu le tshireletso tsa likokoana-hloko: bafuputsi ba ne ba sa fetole le kokoana-hloko ka boeona e (re nile ka tsohle bone lifiliming lekane ka likoluoa tsa ho qoba phoso ena). Ho ena le hoo, ana ho etsa lipatlisiso hlollang e tla thusa bo-rasaense ho lula ka pele ho kokoana-hloko ea ho thibela o nametse libakeng tse lona hlahelang.

Kamoo kotsi ntaramane nonyana

Bafuputsi ba le thahasello khatello bitsoa avian ntaramane A (H7N9). Ho ea ka WHO, ka 2013, kokoana-hloko ena e ama batho ba fetang 900. Leha ho le joalo, boholo ba Maemong a ne amanang le batho ba neng ba sebetsa ka likhoho kaha kokoana-hloko ka boeona e ke sa khone ho sustainably har'a batho.

Tabeng mpe ka ho fetisisa, e leng kokoana-hloko e ka mutate ka foromo e ka jala har'a batho, 'me ka' nang ba qala ho nama joaloka mollo o tsoileng taolong. Kahoo, bo-rasaense ba ho tloha California sebetsa le mefuta e fapaneng ya liphetoho liphatseng tsa lefutso tse liphatsa tsa lefutso ea H7N9, ho bona seo a ka thusa kokoana-hloko ea ho jala har'a batho.

liphetoho liphatseng tsa lefutso e bonolo

Bo-rasaense ba sebetsang ka protheine ka holim 'a kokoana-hloko e bitsoang hemagglutinin H7. E lumella kokoana-hloko ea hore motho a tlame ho amohela lisele tse le ho tšoaetsa ba.

Ba ile ba fumana hore protheine ena ke khona ho liphetoho liphatseng tsa lefutso tse nyenyane ka acid e meraro amino fumana holim 'a kokoana-hloko ea e lumellang ho tlamella molemo ho receptors seleng e fumanoa ka lisele tse ea motho, joalokaha bapisoa le lisele tse avian.

Ka laboratoring, bo-rasaense ba hlahisitse ya hararo sehole haemagglutinin H7 'me ba fumana hore ba ka atleha ho ba le foothold ka lisele tsa tsona li ka batho disampole trachea dinama tse nyenyane tse.

Na ho tla le seoa?

le melao ea tsamaiso Safety hanela ho kena ha liphetoho liphatseng tsa lefutso tsena ka likokoana-hloko tsena H7N9, kahoo le bangodi ea thuto supa hore ha baa bōptjoa kokoana-hloko, 'me feela o ile a sebelisa nang kotsi sekhechana lona. Liphetoho liphatseng tsa lefutso le ea sebele H7N9 emela liteko le eketseha mesebetsi bongata ba kokwanahloko e tse jwale thibetsoe (ka mabaka a totobetseng).

Leha ho le joalo, hore na ho tšaba se fumaneng tsee? Ho bonahala, se yet. Fiona Kalli, setsebi ea matla a ho hema ka Imperial College London, o bolela hore menyetla ea ponahalo tsoa hong ea liphetoho liphatseng tsa lefutso tse tharo kaofela "batlang e le tlaase."

"Phuputso ena e tla re thusa hore re ka hloko ho feta laola likotsi tse amanang le ntaramane avian, 'me ho eketsa tsebo ea rōna ka seo e fetola ka kokoana-hloko ea avian ntaramane e ka ba kotsi," - O ile a re.
