Un grup de cercet\u0103tori de la Academia Rom\u00e2n\u0103 a izolat o bacterie adaptat\u0103 la frig, numit\u0103 Psychrobacter SC65A.3, din ghea\u021b\u0103 veche de aproximativ 5.000 de ani.<\/p>\n

\u00cen testele de laborator, aceast\u0103 bacterie s-a dovedit rezistent\u0103 la 10 din 28 de antibiotice moderne folosite \u00een mod curent pentru infec\u021bii grave ale pl\u0103m\u00e2nilor, pielii, s\u00e2ngelui, tractului urinar \u0219i sistemului reproduc\u0103tor, scrie\u00a0Eco News<\/a>.<\/p>\n

Pentru a ajunge la bacterie, cercet\u0103torii au extras un carotaj de ghea\u021b\u0103 de 25 de metri din Sala Mare a pe\u0219terii Sc\u0103ri\u0219oara, o adev\u0103rat\u0103 \u201earhiv\u0103\u201d \u00eenghe\u021bat\u0103 ce acoper\u0103 aproximativ 13.000 de ani.\u00a0<\/p>\n

Din stratul vechi de 5.000 de ani, au izolat SC65A.3, i-au secven\u021biat genomul \u0219i au identificat genele care \u00eei permit s\u0103 reziste la frig extrem, lipsa nutrien\u021bilor \u0219i chiar la unele antibiotice moderne.<\/p>\n

C\u00e2nd au expus bacteria<\/a>\u00a0la antibiotice utilizate \u00een spitale, aceasta a rezistat la 10 medicamente din opt clase diferite, inclusiv rifampicin\u0103, vancomicin\u0103, ciprofloxacin\u0103, trimetoprim, clindamicin\u0103 \u0219i metronidazol.<\/p>\n

Bacteria este primul exemplu din grupul s\u0103u cu un nivel at\u00e2t de mare de rezisten\u021b\u0103, ceea ce sugereaz\u0103 c\u0103 microorganismele adaptate la frig pot p\u0103stra astfel de gene pe termen lung.<\/p>\n

Genomul s\u0103u con\u021bine peste 100 de gene asociate rezisten\u021bei la antibiotice \u0219i aproximativ 600 cu rol \u00eenc\u0103 necunoscut, unele put\u00e2nd produce substan\u021be care afecteaz\u0103 al\u021bi microbi. \u00cen laborator, SC65A.3 a reu\u0219it s\u0103 inhibe bacterii periculoase precum Staphylococcus aureus, Escherichia coli \u0219i Klebsiella pneumoniae.<\/p>\n

Cristina Purcarea, coautoarea cercet\u0103rii, descrie descoperirea ca fiind \u201ecu dou\u0103 t\u0103i\u0219uri\u201d: bacteria este rezistent\u0103 la mai multe antibiotice, dar are \u0219i poten\u021bial util pentru dezvoltarea unor noi tratamente.<\/p>\n

Descoperirea arat\u0103 c\u0103 rezisten\u021ba la antibiotice a evoluat natural \u00een mediu cu mult \u00eenainte ca oamenii s\u0103 foloseasc\u0103 medicamente \u0219i c\u0103 ghea\u021ba antic\u0103 poate p\u0103stra aceste gene timp de mii de ani.\u00a0<\/p>\n
