%X the transference of the genetic markers and the presence of dna plasmidial in 240 cultures of escherichia coli was investigated. the strains were originated from waste treatment plant (inffluent and effluents) located in ilha do governador, rio de janeiro. by conjugation analysis, e. coli k 12 allowed the isolation of the transconjugants resistent to antibiotics su, sm, tc, cm, ap; heavy metals (cu, hg, and zn) and colicinogenic factors (ia, ib and v) mainly in coliforms isolated cm and ap from the terminals of the treatment plant. the percentual distribution of the plasmids was prevalent in the cultures of e. coli originated from material collected in the effluents and reached a rate higher than 65%.
