title: Colloidal clay inhibits conjugal transfer of R-plasmid R1drd-19 in Escherichia coli.
abstract: Colloidal clay (montmorillonite) strongly inhibited the conjugal transfer of R-plasmid R1drd-19 in Escherichia coli. This finding is discussed in the context of the feasibility of plasmid transfer in environmental waters.
