Teadlased avastasid Brasiilia Atlandi vihmametsas Rio de Janeiro l\u00e4hedal uue seeneliigi, mis suudab nakatada ja tappa \u00e4mblikke. Uus liik sai nimeks Purpureocillium atlanticum ning see kanti Londoni Royal Botanic Gardens, Kew koostatud 2025. aasta k\u00fcmne olulisema uue taime- ja seeneliigi nimekirja.<\/p>\n
Seen avastati 2022. aastal metsast, kus selle viljakeha kasvas v\u00e4lja juba surnud \u00e4mbliku kehast. Teadlaste s\u00f5nul tungivad seene eosed \u00e4mbliku kitiinist l\u00e4bi, levivad tema hemol\u00fcmfis ning suruvad alla peremeesorganismi immuuns\u00fcsteemi, p\u00f5hjustades \u00e4mbliku surma. P\u00e4rast seda kasutab seen \u00e4mbliku keha eoste levitamiseks.<\/p>\n
Uuringu juhtautor, Brasiilia m\u00fckoloog Jo\u00e3o Ara\u00fajo selgitab, et seni peeti sarnaseid seeni Jaapanis, Tais ja USAs \u00fcheks liigiks (Purpureocillium atypicola), kuid detailne geneetiline anal\u00fc\u00fcs n\u00e4itas, et tegelikult on tegu mitme eraldi liigiga. Olulist rolli m\u00e4ngisid uued kaasaskantavad geenij\u00e4rjestusseadmed, mis v\u00f5imaldavad anal\u00fc\u00fcsi l\u00e4bi viia otse looduses.<\/p>\n
\u201eZombiseente\u201c m\u00f5iste on laiemalt tuntuks saanud popkultuuri kaudu, eesk\u00e4tt The Last of Us m\u00e4ngu ja teleseriaali m\u00f5jul. Teadlased r\u00f5hutavad siiski, et Purpureocillium atlanticum ei kujuta ohtu inimestele ja see on rangelt spetsialiseerunud kindlale \u00e4mblikuliigile.<\/p>\n
Ekspertide hinnangul v\u00f5ib seente mitmekesisuse parem tundmine tulevikus aidata kaasa uute ravimite ja antibiootikumide v\u00e4ljat\u00f6\u00f6tamisele. Praegu on teadusele teada vaid ligikaudu k\u00fcmnendik hinnanguliselt olemasolevatest seeneliikidest.<\/p>\n
