Biolo\u017eka Dawn Bazelyov\u00e1 ve spolupr\u00e1ci se zoo v Torontu provedla rozs\u00e1hl\u00fd v\u00fdzkum vlastnost\u00ed los\u00edch slin.

Houby jsou mikroskopick\u00e9 organismy, kter\u00e9 mohou produkovat toxiny, kter\u00e9 mohou zp\u016fsobit onemocn\u011bn\u00ed los\u016f, pokud jsou konzumov\u00e1ny ve velk\u00e9m mno\u017estv\u00ed.
