Polymerase chain reaction-restriction fragment length polymorphism analysis shows divergence among mer determinants from gram-negative soil bacteria indistinguishable by DNA-DNA hybridization.

Abstract excerpt

Mercury resistant (Hgr) bacteria were isolated from four terrestrial sites: three containing high levels of mercury (sites T2, SE, and SO) and one uncontaminated site (SB). The frequencies of Hgr bacteria in the total cultivable populations were 0.05% (SB), 0.69% (SO), 4.8% (SE), and 25% (T2). Between 35 and 100% of the isolates from the four sites contained DNA sequences homologous to a DNA probe from the...
