\nUn virus al \u201egripei canine\u201d se adapteaz\u0103 \u00een direc\u0163ia de a putea infecta oamenii, au avertizat oamenii de \u015ftiin\u0163\u0103.<\/p>\n
Virusul este descendent al unui tip de grip\u0103 aviar\u0103 numit H3N2, care a infectat pentru prima dat\u0103 c\u00e2inii aproximativ \u00een 2006 \u015fi care a evoluat acum pentru a deveni o form\u0103 de grip\u0103 aviar\u0103 adaptat\u0103 la mamifere.<\/p>\n
Datele sugereaz\u0103 c\u0103 gripa aviar\u0103 nu poate sus\u0163ine transmiterea de la o persoan\u0103 la alta. Cu toate acestea, exper\u0163ii au fost \u00eentotdeauna \u00eengrijora\u0163i de faptul c\u0103 acest lucru s-ar putea schimba dac\u0103 virusul ar putea s\u0103 se stabileasc\u0103 \u00eentr-o specie de mamifere, care ar putea, la r\u00e2ndul s\u0103u, s\u0103 devin\u0103 transmisibil \u00eentre mamifere, inclusiv \u00eentre oameni.<\/p>\n
Speciali\u015ftii \u00een grip\u0103 aviar\u0103 de la Universitatea Agricol\u0103 din China au efectuat un studiu pe mai mult de 4.000 de c\u00e2ini, descoperind c\u0103 virusul este mai capabil s\u0103 recunoasc\u0103 receptorii celulelor umane \u015fi s\u0103 se reproduc\u0103 \u00een celulele umane, potrivit Independent.<\/p>\n
Oamenii de \u015ftiin\u0163\u0103 scriu \u00een lucrarea lor, publicat\u0103 \u00een jurnalul eLife: \u201eConform rezultatelor noastre, c\u00e2inii pot servi drept intermediari pentru adaptarea virusurilor gripei aviare la om\u201d.<\/p>\n
Cu toate acestea, \u015fase c\u00e2ini au fost infecta\u0163i \u00een mod inten\u0163ionat cu tulpinile cunoscute de grip\u0103 canin\u0103 H3N2 \u015fi fiecare dintre ei a avut doar o stare de r\u0103u u\u015foar\u0103, simptomele cele mai grave incluz\u00e2nd febr\u0103, str\u0103nut \u015fi tuse.<\/p>\n
Exper\u0163ii britanici au declarat c\u0103 cercetarea este util\u0103 pentru a eviden\u0163ia rolul pe care c\u00e2inii de companie l-ar putea juca drept posibil \u201epacient zero\u201d pentru o viitoare epidemie de grip\u0103 canin\u0103.<\/p>\n
Profesorul James Wood, \u015feful departamentului de medicin\u0103 veterinar\u0103 de la Universitatea din Cambridge, a declarat c\u0103 este \u201edestul de clar\u201d c\u0103 tulpina H3 a gripei aviare a devenit un virus specific c\u00e2inilor.<\/p>\n
El a ad\u0103ugat: “Se pare c\u0103 schimb\u0103rile din virusul canin \u00eel fac mai bine adaptat pentru a se transmite \u00een r\u00e2ndul mamiferelor, a\u015fa cum ne-am putea a\u015ftepta dup\u0103 o perioad\u0103 at\u00e2t de lung\u0103 la c\u00e2ini”.
