Multiple resistance to heavy metals and antibiotics in bacteria isolated from the Riachuelo

Riachuelo is a heavy contaminated course of water, partially surrounding Buenos Aires city. The presence of bacteria resistant to antibiotics and heavy metals was studied. Among the isolated Gram positive colonies, 65, 59 and 48% were resistant to 60 micrograms/ml of Pb++, Zn++ and Cd++, respectivel...
