Nwere ike nnụnụ flu ka mutate na ime ka a ọrịa n'etiti ụmụ mmadụ?

Ọkà mmụta sayensị nwere mụụrụ laabu nwere na nke gosiri na n'okpuru nduzi nke atọ dị mfe mmụba nke avian influenza wee nweta ike na-agbasa site n'otu onye gaa n'ọzọ.

Ma atụla egwu anya n'ihi na a uwe na ndu nchedo: na-eme nnyocha agbanweghị virus onwe ya (anyị na-na na niile hụrụ ezu movies banyere ọdachi zere, njehie a). Kama nke ahụ, ndị a na-echeghị research ga-enyere ndị ọkà mmụta sayensị na-anọ n'ihu nke virus iji gbochie ya nwere na-agbasa.

Olee otú ize ndụ nnụnụ flu

Researchers mmasị nje a na-akpọ avian influenza A (H7N9). Dị ka WHO, na 2013, a virus emetụta karịa 900 ndị mmadụ. O sina dị, ihe ka n'ọnụ ọgụgụ nke ikpe na-metụtara ndị mmadụ na-arụ ọrụ na okuko kemgbe virus adịghị ike sustainably n'etiti ụmụ mmadụ.

Ke kasị njọ ahụ, nje nwere ike mutate n'ime a n'ụdị pụrụ ịgbasa n'etiti ụmụ mmadụ, na ike nwere ike na-amalite na-agbasa dị ka ajọ ọkụ ọgbụgba. N'ihi ya, ndị ọkà mmụta sayensị si California na-arụ ọrụ na a dịgasị iche iche nke mmụba na genome of H7N9, ịhụ ihe nwere ike inyere ndị virus na-agbasa n'etiti ụmụ mmadụ.

mfe mmụba

Ọkà mmụta sayensị na-arụ ọrụ na a protein na elu nke virus akpọ hemagglutinin H7. Ọ na-enye ohere virus eke agbụ iji nọrọ n'ụlọ ya mkpụrụ ndụ na ife efe ha.

Ha chọpụtara na a protein bụ ike nke na obere mmụba na atọ amino asịd hụrụ n'elu nke virus na-enye ohere ya mma jikọtara na cell anabata hụrụ na mmadụ niime ụlọnga, ka tụnyere avian mkpụrụ ndụ.

Na laabu, ọkà mmụta sayensị na-emepụta atọ mmụba haemagglutinin H7 ma chọpụta na ha nwere ike ịga nke ọma na-enweta a foothold na mkpụrụ ndụ na mmadụ oghere eji ekunye ume anụ ahụ n'omume.

Ga-enwe a ọrịa?

Safety ụkpụrụ gbochie ntinye nke ndị a na mmụba a na nje H7N9, otú ahụ ndị malitere nnyocha na-ekwu na ha kere virus, na-na-eji na-benign ibe akwụkwọ ya. Mmụba na ata H7N9 na-anọchi anya nwere na ụba malitere ịrịa ọrụ na-ugbu a machibidoro (maka doro anya ihe).

Ma, ma na-atụ egwu nke ndị a chọpụtara? O yiri, erubeghị. Fiona Kalli, a ọkachamara na akụkụ okuku ume na Immunology na Imperial College London, na-ekwu na Ohere nke a n'otu oge ngosipụta nke niile atọ mmụba "dịtụ ala."

"Nke a na-amụ ga-enyere anyị aka nlezianya chịkwaa ize ndụ metụtara na avian influenza, na ime ka anyị ihe ọmụma nke ihe na-agbanwe na avian influenza virus nwere ike ịbụ nwere ize ndụ," - o kwuru.
