ScienceAlert<\/a> arat\u0103 c\u0103 r\u0103spunsul ar putea fi legat de combina\u021bia dintre mirosurile produse de piele \u0219i microbiomul cutanat, adic\u0103 totalitatea microorganismelor care tr\u0103iesc pe pielea noastr\u0103.<\/p>\nCum au testat cercet\u0103torii preferin\u021bele \u021b\u00e2n\u021barilor<\/p>\n
O echip\u0103 de oameni de \u0219tiin\u021b\u0103 de la Universitatea Interna\u021bional\u0103 din Florida a recrutat 119 voluntari din Miami. Participan\u021bii \u0219i-au introdus bra\u021bele \u00eentr-un dispozitiv special numit olfactometru, un tub folosit pentru a analiza reac\u021bia insectelor la diferite mirosuri.<\/p>\n
Pentru a observa c\u0103tre ce persoane se \u00eendreapt\u0103 mai des, cercet\u0103torii au testat trei specii de \u021b\u00e2n\u021bari: Aedes aegypti (\u021b\u00e2n\u021barul febrei galbene), Aedes albopictus (\u021b\u00e2n\u021barul tigru asiatic) \u0219i Culex quinquefasciatus (\u021b\u00e2n\u021barul comun tropical). Dintre acestea, \u00een Rom\u00e2nia a ajuns p\u00e2n\u0103 \u00een prezent doar Aedes albopictus, cunoscut drept \u021b\u00e2n\u021barul tigru asiatic.<\/p>\n
Rezultatele au ar\u0103tat c\u0103 o persoan\u0103 poate fi mai atractiv\u0103 pentru o anumit\u0103 specie de \u021b\u00e2n\u021bari, dar nu neap\u0103rat \u0219i pentru toate celelalte.<\/p>\n
Mirosul pielii, un factor important<\/p>\n
Mirosul natural al pielii este produs de secre\u021bii care sunt transformate de bacteriile de pe corp \u00een compu\u0219i organici volatili, substan\u021be pe care \u021b\u00e2n\u021barii le pot detecta.<\/p>\n
Cercet\u0103torii au identificat sute de tipuri de bacterii pe pielea participan\u021bilor \u0219i au observat c\u0103 anumite bacterii ap\u0103reau mai frecvent la persoanele care atr\u0103geau mai mul\u021bi \u021b\u00e2n\u021bari.<\/p>\n
Printre bacteriile asociate cu o atrac\u021bie mai mare pentru \u021b\u00e2n\u021bari s-au num\u0103rat Corynebacterium kefirresidentii, Cutibacterium granulosum \u0219i Staphylococcus epidermidis, bacterii care se g\u0103sesc \u00een mod natural pe pielea uman\u0103. Aceste microorganisme ar putea transmite \u021b\u00e2n\u021barilor un semnal chimic care indic\u0103 prezen\u021ba unei gazde potrivite.<\/p>\n
Cercet\u0103torii exploreaz\u0103 modificarea microbiomului pielii<\/p>\n
Cercet\u0103torii spun c\u0103 \u00een\u021belegerea modului \u00een care \u021b\u00e2n\u021barii aleg oamenii ar putea ajuta la dezvoltarea unor metode mai eficiente de protec\u021bie \u00eempotriva mu\u0219c\u0103turilor.<\/p>\n
Pe viitor, oamenii de \u0219tiin\u021b\u0103 sper\u0103 s\u0103 poat\u0103 crea repelente mai precise sau chiar metode prin care microbiomul pielii s\u0103 fie modificat astfel \u00eenc\u00e2t oamenii s\u0103 devin\u0103 mai pu\u021bin atractivi pentru \u021b\u00e2n\u021bari.<\/p>\n
Descoperirea este important\u0103 \u0219i pentru s\u0103n\u0103tatea public\u0103, deoarece \u021b\u00e2n\u021barii sunt considera\u021bi printre cei mai periculo\u0219i transmi\u021b\u0103tori de boli, fiind responsabili de r\u0103sp\u00e2ndirea unor infec\u021bii precum malaria, dengue, virusul West Nile \u0219i altele.<\/p>\n","protected":false},"excerpt":{"rendered":"\u021a\u00e2n\u021barii sunt atra\u0219i de mai multe semnale emise de oameni, inclusiv dioxidul de carbon eliminat prin respira\u021bie, c\u0103ldura…\n","protected":false},"author":2,"featured_media":251046,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":"","_share_on_mastodon":"0"},"categories":[10],"tags":[69507,32,33,31,69508,36,37,27,34,35,69509,25,41,40,38,39,215,26,25559,28,29,30],"class_list":["post-251045","post","type-post","status-publish","format-standard","has-post-thumbnail","category-romania","tag-boli-transmise-de-tantari","tag-breaking-news","tag-breakingnews","tag-cele-mai-populare-subiecte","tag-cercetare-stiintifica","tag-featured-news","tag-featurednews","tag-headlines","tag-latest-news","tag-latestnews","tag-microbiomul-pielii","tag-news","tag-ro","tag-romana","tag-romania","tag-romanian","tag-sanatate","tag-stiri","tag-tantari","tag-titluri","tag-top-stories","tag-topstories"],"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@ro\/117038859125567086","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ro\/wp-json\/wp\/v2\/posts\/251045","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/ro\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/ro\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ro\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ro\/wp-json\/wp\/v2\/comments?post=251045"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ro\/wp-json\/wp\/v2\/posts\/251045\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ro\/wp-json\/wp\/v2\/media\/251046"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ro\/wp-json\/wp\/v2\/media?parent=251045"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ro\/wp-json\/wp\/v2\/categories?post=251045"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ro\/wp-json\/wp\/v2\/tags?post=251045"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
