\u00cen 2022, un lot de embrioni de g\u0103in\u0103 \u0219i ra\u021b\u0103 care au murit \u00eenainte de eclozare a ajuns la un laborator veterinar din China pentru analize.<\/p>\n

\u00cen \u021besutul cerebral al acestora, cercet\u0103torii au identificat Acinetobacter baumannii, un agent patogen clasificat de Organiza\u021bia Mondial\u0103 a S\u0103n\u0103t\u0103\u021bii drept \u201ePrioritatea 1\u201d, arat\u0103 Science Alert<\/a>.<\/p>\n

Bacteria este cunoscut\u0103 pentru focarele din sec\u021biile de terapie intensiv\u0103, deoarece este rezistent\u0103 chiar \u0219i la antibioticele folosite ca ultim\u0103 solu\u021bie.<\/p>\n

\u00cen ultimii ani, aceasta a \u00eenceput s\u0103 fie recunoscut\u0103 \u0219i ca agent patogen zoonotic, capabil s\u0103 circule \u00eentre animale \u0219i oameni.<\/p>\n

Ce au descoperit cercet\u0103torii despre animalele de ferm\u0103<\/h2>\n

De mult timp se crede c\u0103 animalele de ferm\u0103 ar putea contribui la r\u0103sp\u00e2ndirea rezisten\u021bei la antibiotice \u00een cazul superbacteriilor.<\/p>\n

Totu\u0219i, \u00een mod surprinz\u0103tor, tulpinile izolate din p\u0103s\u0103rile analizate nu prezentau o rezisten\u021b\u0103 semnificativ\u0103 la antibiotice.<\/p>\n

Compar\u00e2nd aceste date genetice cu cele provenite de la oameni \u0219i animale de companie, precum pisici \u0219i c\u00e2ini, cercet\u0103torii au descoperit c\u0103 principala surs\u0103 de \u00eengrijorare era mult mai aproape de oameni.<\/p>\n

Ei au analizat date genetice provenite din 509 probe de A. baumannii recoltate de la animale din 17 \u021b\u0103ri \u0219i 33 de specii, de la berze albe din Polonia p\u00e2n\u0103 la pisici, c\u00e2ini \u0219i cai trata\u021bi \u00een clinici veterinare din Europa.<\/p>\n

Aceste date au fost comparate cu mii de probe clinice umane din acelea\u0219i regiuni, precum \u0219i cu noile probe provenite de la p\u0103s\u0103ri.<\/p>\n

Rezultatele nu sunt lini\u0219titoare pentru proprietarii de animale de companie<\/h2>\n

Folosind un sistem care clasific\u0103 tulpinile \u00een a\u0219a-numite \u201eclone interna\u021bionale\u201d \u2013 acelea\u0219i linii genetice responsabile pentru focare \u00een spitale din \u00eentreaga lume \u2013 echipa a constatat c\u0103 mai multe dintre aceste clone, inclusiv una numit\u0103 ST25, ap\u0103reau frecvent la animalele de companie.<\/p>\n

Doar tulpina ST25 a fost identificat\u0103 la nou\u0103 specii de animale, \u00een special la pisici, c\u00e2ini \u0219i cai.<\/p>\n

Bacteriile izolate de la aceste animale erau aproape identice din punct de vedere genetic cu tulpinile care infectau pacien\u021bi din spitalele aflate \u00een apropiere, av\u00e2nd o similaritate genomic\u0103 de peste 99%, iar \u00een unele cazuri de peste 99,5%.<\/p>\n

\u00cen schimb, tulpinile identificate la animalele de ferm\u0103, p\u0103s\u0103ri \u0219i animale s\u0103lbatice erau mult mai diferite, cu o similaritate de aproximativ 97-98% fa\u021b\u0103 de cele \u00eent\u00e2lnite la oameni.<\/p>\n

Pisicile \u0219i c\u00e2inii purtau inclusiv gene de rezisten\u021b\u0103 la carbapeneme, antibiotice utilizate atunci c\u00e2nd alte tratamente nu mai func\u021bioneaz\u0103 \u0219i interzise \u00een cre\u0219terea animalelor de ferm\u0103. Aceste gene nu au fost identificate \u00een niciuna dintre probele provenite de la animale de ferm\u0103, p\u0103s\u0103ri sau animale s\u0103lbatice.<\/p>\n

Totu\u0219i, cercet\u0103torii subliniaz\u0103 c\u0103 rezultatele nu \u00eenseamn\u0103 c\u0103 un c\u00e2ine sau o pisic\u0103 transmite automat aceast\u0103 bacterie st\u0103p\u00e2nului.<\/p>\n

P\u00e2n\u0103 \u00een prezent, nu exist\u0103 dovezi directe c\u0103 bacteria a trecut de la un anumit animal de companie la o anumit\u0103 persoan\u0103. Studiul indic\u0103 doar, pe baza asem\u0103n\u0103rilor genetice, c\u0103 aceast\u0103 transmitere este posibil\u0103 \u0219i ar putea avea loc de mai mult timp.<\/p>\n","protected":false},"excerpt":{"rendered":"
