Norteko Ferrokarrilla/2014-03-08/Plastisferan Vibrioak

Geroz eta hondakin plastiko gehiago daude ozeanoan. Iraunkorrak dira, gainera, eta denboraren poderioz bizidunak itsasten zaizkie. Hain zuzen ere, plastikoaren hidrofobikotasunak aukera ematen die bizitzeko normalean itsaso sakonean biziko ez liratekeen mikrobioei. Baina bizi dira, eta komunitate osoak osatzen dituzte. Adituek komunitateetako mikroboen multzoari plastisfera deitzen diote. Orain, plastisfera albiste bihurtu da, aztertutako Atlantikoko lagin batzuetan Vibrio geberoko bakterioak topatu dituztelako, gizakiengan kolera gaixotasuna ergiten dutenak.
